Action: Swimming
What is the action force?
What is the reaction force?
Action force: Swimmer pushes the water backwards
Reaction force: The water pushes the swimmer forward.
300
What is inertia?
The tendency of an object to resist a change in it's motion (to resist acceleration).

38.43 N
500
Using physics terms, explain why small children have to use lighter bowling balls than adults if they want to throw the ball at the as fast as them.
They can't apply as much force as the adults do, so they need a ball with less mass to be able to accelerate it at the same rate.
500
Using physics terms, explain how the picture above relates to Newton's 1st law of motion. (For example: explain where the balanced/unbalanced forces are coming from/going)
When the bike hit the wall, the wall applied an unbalanced force to it, which accelerated it rapidly to 0mph, but the wall did not apply any unbalanced force to the driver, so he continued at the same velocity as when he hit the wall.
