Newtons First Law
AN object at rest reamins at rest and an object in motion maintains its velocity unless it experiences an unbalanced force
an example of this is when you ride in a car and the car comes to a stop, you can feel your body continue to move forward. Your seat belt and the friction between your pants and the seat stop your forward motion.
Newtons Second Law
The unbalanced force acting on an object equals the objects mass times its acceleration
an example of this is when you are pushing an empty shopping cart and pushing the same cart filled with groceries
