Amplify Force and Motion

In order for an object to speed up, the direction of the force is:

• in any direction

• in the same direction as the object's motion

• in the opposite direction of the object's motion

In order for an object to start moving, the force must come from

• the same direction as the object's motion

• the opposite direction as the object's motion

• any direction

In order for an object to stop moving, the force must come from

• the same direction as the object's motion

• the opposite direction as the object's motion

• any direction.
