Answer Key

#	Answer
1	A force is a push or a pull on an object.
2	You can push or pull it to make it move.
3	A push makes the swing move forward.
4	Gravity is a force that pulls objects toward Earth.
5	Friction is a force that slows moving objects down when surfaces rub together.
6	Gravity helps the ball fall to the ground.
7	The table supports the book with an upward force.
8	Friction between your shoes and the ground helps you keep from slipping.
9	The forces balance, so the object does not change its motion.
10	Magnetism is a force that can pull some objects.
11	Carpet creates more friction, so it is harder to move the box.
12	A stronger push can make the ball move faster or go farther.
13	A pull makes the drawer move toward you.
14	Magnets only attract certain materials, such as iron or steel.
15	Friction is working on the ball and slowing it down.
16	Gravity pulls the person back down to the ground.
17	You can put the object on wheels or rollers to reduce friction.
18	Their forces work together, creating a stronger push.
19	Balanced forces cancel each other and do not change motion, while unbalanced forces change an object's motion.
20	A push or a pull could make the cart start moving by creating an unbalanced force.
