An engineer is designing the foundation of large building and wants to be sure that movement in the ground will do as little damage to the building as possible. Which building material would be best to use in the foundation?
Steel-reinforced concrete is a better material for foundation where movement in the ground is envisaged.
The kind of material used for the foundation of a building greatly impacts the ability of that building to cope with movements in the ground such as during earthquakes.
For instance, when the foundation is made of brick or concrete which has a low ductility, these materials are incapable of absorbing a lot of energy. However, steel-reinforced concrete is a better material for foundation where movement in the ground is envisaged.

Think about an object to which you have applied a force to change its velocity. Now think about an object that has a smaller or larger mass than that object. Answer the following prompt:
Describe a situation in which the force required to change the velocity of an object changes based on the mass of the object.
Describe a simple experiment you could perform that would generate data to provide evidence that the change in an object’s motion depends on either the forces on the object or the mass of the object.
Answer:
Explanation:
F=ma
1. Describe a situation in which the force required to change the velocity of an object changes based on the mass of the object.
Place both a volleyball and a bowling ball on the lower surface of an inclined plane (e.g., on an asphalt road going uphill). Roll each one up the hill and measure the difference in effort (force) each requires to start moving.
2. Describe a simple experiment you could perform that would generate data to provide evidence that the change in an object’s motion depends on either the forces on the object or the mass of the object.
Use a coiled spring to propel two objects above (volleyball and bowling ball) and observe both the distance and the velocity after leavging the spring.
Apply Newton’s second law to calculate the frictional force needed to hold a 15 g pen in your fingers and keep it from falling
Answer:
0.1962N.
Explanation:
Weight is a force, so we use newtons second law which states F=ma. So the weight of a watermelon on earth is 2kg x 9.81m/s², which is 19.62N (newtons). On the moon it weighs 2 x 1.63 which is 3.26N.
The weight of the pen is 0.02 x 9.81, which is 0.1962N. If the pen is not to fall the frictional force needs to be equal to this force,
so the answer is 0.1962N.

Suppose that scientists observe violent gas eruptions on a planet with an acceleration due to gravity of 3.6 m/s2.
The jets throw sand and dust about 75 m
above the surface.
What is the speed i
of the material just as it leaves the surface?
Scientists estimate that the jets originate as high‑pressure gas speeds through vents just below ground at about 150 km/h.
How much energy per kilogram of material does the jet lose to nonconservative forces as the high‑speed matter forces its way to the surface and into the air?
Answer: The velocity with which the sand throw is 24.2 m/s.
Explanation:
Explanation:
acceleration due to gravity, a = 3.9 m/s2
height, h = 75 m
final velocity, v = 0
Let the initial velocity at the time of throw is u.
Use third equation of motion
The velocity with which the sand throw is 24.2 m/s.
Why does it hurt more when you fall on concrete than on grass?
Answer:
Smaller forces are easier on your legs and you prefer to land on soft grass. Momentum/impulse explanation: Whether you land on concrete or soft grass, your change in momentum will be identical. A hard surface that brings you to a stop in 0.01 s requires a much larger force of 15,000 N.

Explanation:
The forces act on skateboard when we push it are , external force of 500N and friction force because of the surface.
What is the Newton's First law of motion?The stationary object will remain stationary or the subject in the motion will keep its motion until or unless the external force is not applied .
What will happen when we apply 500 N external force to the skateboard?We know the only force which is going to oppose the applied 500N force is the friction force due to surface.First as we will apply the external force the skateboard and the box will start gaining the velocity and the accelerationAfter some time because of the friction force the skateboard and the box will start losing its velocity because of the friction force and the combined mass they are having and at the end it will stop moving forward. it is also depends on their mass also.If we put different types of objects on the skateboard then the time period of lost of velocity will be different .If we put object having more mass then the combined system (skateboard + object ) will start losing its velocity quickly . and visa versa for the object having less mass.So, by the Newton's first law of motion we can understand this concept.

Which statement best describes the main idea of the poem
Two roads diverged in a yellow wood, And sorry I could not travel both And be one traveler, long I stood And looked down one as far as I could To where it bent in the undergrowth; Then took the other, as just as fair, And having perhaps the better claim, Because it was grassy and wanted wear; Though as for that the passing there Had worn them really about the same, And both that morning equally lay In leaves no step had trodden black. Oh, I kept the first for another day! Yet knowing how way leads on to way, I doubted if I should ever come back. I shall be telling this with a sigh Somewhere ages and ages hence: Two roads diverged in a wood, and I— I took the one less traveled by, And that has made all the difference.

what is the weight of a 1.8 kg computer
Answer:
17.64 Newtons
Explanation:
In order to find the weight of an object we take the mass in kilograms and multiply it by the gravitational constant (9.8), which is 1.8 * 9.8 = 17.74 Newtons.
Weight is force on the body of given mass 1.8 Kg. Weight is 17.64 N.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Weight of body is force due to gravity,
F = mg
F = 1.8*9.8
F = 17.64 N
Weight of the body is given as 17.64 N.
Weight is force on the body of given mass 1.8 Kg. Weight is 17.64 N.

When a 12 newton horizontal force is applied to a box on a horizontal
table top, the box remains at rest. The force of static friction acting on
the box is .....
The force of static friction acting on the box is greater than the applied horizontal force.
Force is known to be the reason for motion according to Newton's first law of motion. An object will move when it has been acted upon by an external force.
In this case, a box lying on a table has been acted upon by an external force of 12 newton but the box remains at rest. This simply means that the applied force is less than the force of static friction acting on the box.

Kennedy is planning an investigation into the transformation between Kinetic and potential energy using objects she found around her house
The object that is best used to study the transformation between kinetic and potential energy is the clock because it has a pendulum.
A pendulum can be used to study the conversion of kinetic energy to potential energy. As the pendulum swings from side to side energy is converted from potential energy to kinetic energy and back to potential energy.
The potential energy is minimum and the kinetic energy is maximum at the middle of the pendulum. At both ends of the pendulum, the potential energy of the system is maximum.

Explanation:
what can be respresented by a force arrow weight or mass
Answer:
Force arrows are used to represent both the magnitude and direction of forces. The length of the arrow corresponds to the magnitude of the force, with longer arrows indicating forces with larger magnitudes. The direction of the arrow corresponds to the actual direction that the force is being exerted. Force arrows are used by scientists and engineers to predict the motion of an object based on the forces that are applied to it.
Let's go back to Amil and his box for a moment. To represent the force that he is exerting on the box, we can draw the box and then show the force using a force arrow, like this:
Explanation:
How would our force arrow change if he pushed the box with twice as much force? Because the magnitude of the force is doubled, the length of the force arrow should also be doubled.
Now, what if he didn't push directly to the right, but instead his arms made a 30-degree angle with the ground? In that case, the direction of the force arrow needs to change to show the direction in which the force is applied.
