Newton's First Law states that an object will remain stationary or in a uniform motion in a straight line unless acted upon by a force.
An example of Newton's First Law is this apple. The apple right here won't move unless it is acted upon by a force like my hand.
Newton's Second Law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
An example of Newton's Second Law of Motion is an apple compared to a building. Say I were to push an apple across the street. We can say this is not much acceleration since its mass is small. But if I were able to push a building somehow with the net force of my hand (if I had powers), the acceleration is greater as it would take a bigger net force to counteract the mass to be able to push it along the street.
Newton's Third Law states that for every action (force) in nature there is an equal and opposite reaction.
For example, a bat hitting baseball would result in the baseball making the bat go to the left (action force) and the bat would make the baseball go to the right (reaction force)
