Did You Know?A Book About Balls and RampsBy: The Cedar Wood Kindergarten Team

Did you know that balls have many characteristics that are affected by gravity, inertia, momentum and friction?

Balls can be rough, smooth, hard or squishy.

The material a ball is made of affects the way it moves.

Did you know that balls have many characteristics that are affected by gravity, inertia, momentum and friction?

Gravity is an invisible force that pulls balls down ramps or down to the ground when dropped.

Inertia keeps a ball still or it keeps a ball moving at the same speed.

Momentum is the speed the ball moves depending on its properties.

Friction is the force that slows a ball down when it rolls down a ramp or rolls on the ground.
