Force and Motion Review

Choose the BEST answer that describes how the mass of an object affects its motion.

• The greater the mass of an object, the slower the motion of the object.

• The greater the mass of an object, the faster the motion of the object.

• The greater the mass of an object, the greater the force to move the object.

• The greater the mass of an object, the greater the distance the object will travel.

The diagram models the forces acting on a box.

Which of the following best describes the motion of the box?

Which of the following best describes the relationship between force and motion?

• Force is not needed to change the motion of an object

• A force can change the speed or direction of an object's motion

• Motion can occur without any force

• Force and motion are unrelated

What unit is used to measure force?

• Kilograms

• Meters per second

• Newtons

• Joules

What does Newton's first law of motion state?

• For every action, there is an equal and opposite reaction.

• Force equals mass times acceleration.

• An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

• The acceleration of an object depends on the mass of the object and the amount of force applied.

If you push a toy car with a greater force, what will happen to its motion?

• It will move slower

• It will move faster

• It will stop moving

• It will move in the opposite direction

What happens to the motion of an object when an unbalanced force acts on it?

• It continues moving at the same speed.

• It changes direction.

• It stops immediately.

• It changes speed or direction.
