Rule 1: An object at rest will remain at rest until acted upon by an external force
you just threw that apple at me!
The apple remained at rest until the girl threw it at the other girl. Once the apple hit the girls face, the apple stopped.
A basketball has more mass than a tennis ball. So if the athlete were to roll the basketball and tennis ball at the same time with the same force, the tennis ball would go faster because and farther because it has less mass then the basketball.
Force= mass * acceleration
DONT BREAK THE BENCH!!!!!
The dog and the bench are applying the same amount of force and they are also applying the oppisite re-action. So the bench is pulling and the dog is pulling.
Rule 3: For every action, there is an equal and opposite re-action
