Force and Motion

Define force:

• A push or pull that causes an object to move, stop, or change direction or speed

• when you change position

• How fast or slow an object is moving

• Where something is

Define motion:

• A push or pull that causes an object to move, stop, or change direction or speed.

• How fast or slow an object is moving.

• when you change position

• where something is

Define position:

• A push or pull that causes an object to move, stop, or change direction or speed.

• How fast or slow an object is moving.

• when you change position

• where something is

Define speed:

• where something is

• when you change position

• How fast or slow an object is moving.

• A push or pull that causes an object to move, stop, or change direction or speed.

Define friction:

• slows or stops motion when two objects rub together

• How fast or slow an object is moving.

• when you change position

• where something is

This is an example of a position.

• True

• False

The more mass an object has, the less force you will need to move it.

• True

• False

A ball will roll farther on wood floors than on carpet because the wood floors have less friction.

• True

• False

The less force I put behind throwing a baseball, the farther it will travel.

• True

• False

What is kinetic energy?

• the energy an object has when it is in motion

• the stored energy an object has because of its position or state

• something that slows an object down

• a push or a pull
