Force & Motion

Which of the following is an example of HOW the motion of an object can change?

• Slow Down

• Thrusters

• Mass

• Velocity

When you push an object that is at rest how can the motion of that object change?

• Slow down

• Start moving

• Remain at rest

• Stop moving

When you apply a strong force to an object in the same direction of its motion what will happen to the motion of the object?

• Slow down

• Change direction

• Stop

• Speed Up

When you apply a strong force in the opposite direction to the motion of an already slow moving object what is the most likely change in motion?

• Speed up in the same direction of its current motion.

• Stop moving for a second and then begin to move again in the opposite direction.

• The object will change directions and continue moving.

• The object will not be affected by a strong force, only a weak force will make a difference.

What is a push or a pull that can change the motion of an object called?

• Force

• Friction

• Velocity

• Speed

A force is required to change the _______ of an object.

• velocity

• mass

• matter

• color

How an object changes velocity depends on the direction of the force exerted on that object.

• True

• False

A stronger force can cause a ______ change in velocity.

• weaker

• equal

• greater

• forces do not change the velocity of an object

When two objects collide, both objects experience the same amount f force, How each object responds after the collision depends on what?

• How much velocity each object has.

• How much friction affects each car.

• How much mass each object has.

• How much matter was lost in the collision.

When in a collision both objects receive an equal force strength but the forces are exerted in ______ directions.

• forward

• backward

• opposite

• same
