TCAP Review Force and Motion

A student is investigating acceleration using balls with different masses. The student pushes each ball on a flat surface and records its acceleration. The table shows his observations.

Ball Mass (kg) Force (N) Acceleration (m/s^2)

1 30 100 7.35

2 40 100 5.5

3 45 100 4.9

4 50 100 4.41

Which claim can the student make using his observations?

• a. A ball with a mass of 15 kg will have an acceleration that is less than 3.3 ft/s² when pushed with a force of 100 N.

• a. A ball with a mass of 60 kg will have an acceleration that is greater than 4.49 m/s² when pushed with a force of 100 N.

• a. A ball with a mass of 35 kg will have an acceleration that is nore than 7.35 m/s² when pushed with a force of 100 N.

• A ball with a mass of 20 kg will have an acceleration that is greater than 5.5 m/s² when pushed with a force of 100 N

The graph shows the amount of force needed to accelerate a baseball and a softball at the same rate. Point P shows the data for the baseball, and Point Q shows the data for the softball. How does the graph provide evidence that the force needed to accelerate the objects is proportional to their mass?

• The x-value of Q is greater than the x-value of P.

• A curved line can be drawn between P, Q, and the point (0,0).

• A straight line can be drawn between P, Q, and the point (0,0).

• The y-value of Q is greater than the y-value of P.

A student moves 4 boxes along a friction-less surface. The student claims that the force required to move each box the same distance is proportional to the mass of each box. Which argument BEST supports the student's claim?

• The box with the highest mass requires the most force to move the same distance.

• The box with the highest acceleration requires the most force to move the same distance.

• The box with the lowest acceleration requires the most force to move the same distance.

• The box with the lowest mass requires the most force to move the same distance.

A student is investigating inertia and acceleration. Assuming the force acting on the objects is constant, which claim about inertia and acceleration is supported by the data?

• An object with a lower mass has less inertia, which causes it to speed up less quickly.

• An object with a higher mass has more inertia, which causes it to speed up less quickly

• An object with a higher mass has less inertia, which causes it to speed up more quickly.

• An object with a lower mass has more inertia, which causes it to speed up more quickly.

• The Law of Conservation of Momentum

What is the main difference between speed and velocity?

• Speed is a measure of distance, while velocity is a measure of displacement.

• Speed is a scalar quantity, while velocity is a vector quantity.

• Speed can only increase, while velocity can increase or decrease.

• There is no difference; they are the same thing.

What is the term used to describe the change in position of an object?

• Speed

• Velocity

• Displacement

• Acceleration

What is work?

• The distance an object moves.

• The force applied to an object times the distance it moves in the direction of the force.

• The speed of an object.

• The force applied against an object.
