Forces and Simple Machines Quiz

What is force?

• The ability to do work or cause change

• A type of simple machine

• A measure of how fast something is moving

• The amount of space an object takes up

Which of the following is NOT a type of simple machine?

If you push a toy car gently, it moves slowly. If you push it with more force, it moves faster. This demonstrates that force affects:

• The color of the toy car

• The size of the toy car

• The speed of the toy car

• The weight of the toy car

A seesaw is an example of which type of simple machine?

• Lever

• Wheel and Axle

• Pulley

• Screw

What does a pulley system do?

• It decreases the amount of force needed to lift an object

• It changes the direction of the applied force

• Both A and B

• Neither A nor B

Which simple machine is made up of a wheel with a rope or chain wrapped around it?

• Lever

• Pulley

• Inclined Plane

• Wheel and Axle

How does an inclined plane make work easier?

• By increasing the distance over which a force is applied

• By changing the direction of the applied force

• By decreasing the distance over which a force is applied

• By requiring more force to move an object

What happens to the force required to lift an object when you use a simple machine?

• It increases

• It decreases

• It stays the same

• It first decreases, then increases

Which of the following is an example of a wheel and axle?

• A staircase

• A door knob

• A slide

• A shovel

What is the primary purpose of a screw as a simple machine?
