Speaking of acceleration, Newton's second law is acceleration equals force divided by mass.
As you can see, these cars have the same force, but the blue car has more mass, so the grey car has a greater acceleration.
Lastly, Newton's third law is every action will have an equal and opposite reaction.
Woah! Did you see that!? That is an example to Newton's third law. The blue car hit the grey car with 250 Newtons of force. That means that the grey car hit the blue car with also 250 N of force, but in the opposite direction.
Thank you so much more teaching me about Newton's three laws of motion!
