Force and Motion

Change in velocity per unit of time.

• Speed

• Acceleration

• Velocity

• Motion

The diagram represents two students pushing and pulling an object in the same direction. Which statement best describes the result of the forces?

• The object will not move because the forces are not the same.

• The object will move in the direction of the combined forces.

• The lesser force applied is not enough to move the object.

• The combined forces on the object cancels each other out.
