Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. Kind of like this cherry it wont move unless acted on by another force.
Newtons second law states mass times force equals acceleration kind of like the bigger the mass the less it will accelerate. The same thing is happening in the picture the smaller car is going faster because it does not have to carry as much mass.
Newtons third law is for every action, there is an equal and opposite reaction. Kind of like when the guy hits his arm on the chair so the chair hurts his hand back for every action there is a equal and opposite reaction
