Review Forces and Motion

The Space Shuttle launch is an example of this law.

​

Newton's 3rd Law says every action has an opposite and equal reaction

Match

Match the action and reaction forces:

• thrust pushing down

• rocket lifting up

• Ball gets thrown down;

action

reaction

Ball bounces back up

• action

• reaction

• Ball bounces back up

Labelling

Label the action and reaction forces on the bat.

Drag labels to their correct position on the image

Action

Reaction

Ball flys away

Bat hits ball

​Explain how this law means heavy things are hard to move to your table partner.

Newton's 2nd Law says Force = mass x acceleration

Multiple Choice

The books are harder to move than a stack of feathers because:

• They have more mass so require more force.

• They have less mass so require less force.

• They have no mass.

• They have more mass so require less force.

Newton's 1st Law says an object in motion will stay in motion and an object at rest will stay at rest until acted on by another force.

How are the planets orbiting an example of Newton's First Law? Explain it to your table partner.
