What do simple machines help you do?

• Use more force to move an object

• Use less force to move an object

• Increase the weight of an object

• Make objects larger

What is one way simple machines work?

• They change the color of objects.

• They change the direction of the force.

• They make objects disappear.

• They create new forces.

What is another way simple machines work?

• They make objects heavier.

• They reduce the size of objects.

• They stop all movement.

What is an inclined plane?

• A flat surface

• A slanted surface

• A curved surface

• A bumpy surface

How do inclined planes make work easier?

• By decreasing the distance

• By increasing the distance

• By making objects heavier

• By making objects lighter

Why is it easier to move a heavy box up a ramp?

• Because the box becomes lighter

• Because the ramp is slippery
