Newton's First Law

Newton's First Law states that an object in motion stays in motion and an object at rest stays at rest unless acted on by an unbalanced force. This relates to the toy car in that in order for it to start moving a person (the outside force) must push it. The push acts as an unbalanced force. The car will keep moving unless an unbalanced force stops it, such as a person stopping it, it hitting the ground, or the friction that the car and the table create.

Newton's Second Law

Newton's Second Law is force equals mass times acceleration. The acceleration depends on the force and mass. The car shows this law in that in order for it to go fast someone has to push it with a greater force than the mass of the car. The push that the person creates acts as an unbalanced force just as in Newton's First Law.

Newton's Third Law

Newton's Third Law states that every force has an equal and opposite reaction force. For example, if the car were to hit a wall going 3 mph, it would bounce back in the opposite direction with an equal force of 3 mph. The wall acts as the unbalanced force in this case.

Forces Acting on the Car

There were many forces acting on the car, most unbalanced. For Newton's First Law, you must have an unbalanced force in order for the car to start moving and for the car to stop. An example for this would be a person stopping the car, the car falling off the table, or just the friction that the car and the table create. The forces acting in Newton's Second Law would be the push that the person creates to start the car in motion just as in Newton's First Law. The push would be an unbalanced force. Lastly, the forces acting in the last law would be when the car hits the wall in order for it to stop. The wall acts as an unbalanced force, causing the car to stop in its motion.
