Newton's Second Law in Daily Life

Have you ever played a toy car? most certainly had never all played toy cars. Did you know that in playing the toy car we apply Newton's second law? Well, in this article I will discuss Newton's second law that happens when we play toy cars.

When we play toy cars surely we tied a rope to pull the toy car. Once, when I was in elementary school I have ever played toy car. But I do not know that in playing the toy car is no law newton in it. Now did I know that there are laws in play toy cars newton. Newton's second law theory there is that if we apply a force (F) on a body of mass (m) is silent, then the object will move / change position from its initial position. That suggests that the force acting on the object causing the acceleration. Well, in playing toy car we also exerts a force on the rope that we tied the last toy car by pulling. When we pulled the toy car is certainly going to move. The speed of the toy car moves depends on the force and the mass of the toy car. If written in the formula becomes:

a=∑F/m   or  ƩF = m . a


I also conducted an experiment to prove the formula above. Experiments is to use a toy car as well, just a rope to pull me replace it with rubber. The trick is as follows:

For those who do not use a block of wood

1. Prepare the materials (car toys, rubber bands and wooden beams)
2. Tie a rubber band on a toy car.
3. Pull the toy car.
4. Observe, what happens to the rubber band.

For those who use a block of wood

1. Prepare the materials (car toys, rubber bands and wooden beams)
2. Tie a rubber band on a toy car.
3. Add loads of wood beams on the toy car.
4. Pull the toy car.
5. Observe, what happens to the rubber band.

From the above two experiments we came to the conclusion that the mass affect style and speed. It is seen in the first experiment, which used a rubber band did not have the length. While in the second experiment, which used a rubber band having the length. That's because in the second experiment we added wood beams add mass as a load for a toy car.

Problem:
A toy car of mass 1 kg is pulled with a force of 2 N to move. If the friction between the tire and the floor is negligible, what is the acceleration experienced by the car?
Completion:

Known : F = 2N

              m = 1 kg

Ask : a = …. ?

Answer : a=F/m

                =(2 N)/(1 kg)

                = 2 m/s^2
