Question

3rd law
checking for understanding
describe the reaction forces in the action - reaction pair.
example
action: bat pushes ball to the right.
reaction: ball pushes bat to the left.
action: bike pushes down on the ground.
reaction
action: fish pushes water backwards.
reaction
a tennis ball hits the ground and the ground hits the ball with equal force in the opposite direction.
where will the ball go next? draw its new location.
example of newtons 3rd law
draw an example of newtons 3rd law in the space above. explain why your drawing represents the law in the space below.

Explanation:

Step1: Recall Newton's 3rd Law

For every action, there is an equal and opposite reaction.

Step2: Analyze bike - ground example

If the bike pushes down on the ground (action), the ground pushes up on the bike (reaction).

Step3: Analyze fish - water example

If the fish pushes water backward (action), the water pushes the fish forward (reaction).

Step4: Analyze tennis - ball example

When the ball hits the ground and the ground hits the ball with equal force in the opposite direction, the ball will bounce back up.

Answer:

• For bike - ground: Reaction is ground pushes up on the bike.
• For fish - water: Reaction is water pushes fish forward.
• For tennis - ball: Draw the ball bouncing back up.
