#### Transcript of Newton Laws of Motion

Is the first newton law being applied in this photo? The answer is YES! The car remained in motion until the trashcan blocked it from inertia. Since, the man in the car was moving at the same speed as the car, he wanted to keep going even though the car had stopped. Unfortunately, the man flew out of the car, because he had no seat belt to stop inertia. The trashcan stopping the car from inertia was the first newton law being applied in this photo.
This picture is an example of the third newton law. The third newton law is also known as the law of action and reaction. It's known for that because for every action there is a reaction. In the photo above shows how the man is applying force to the brick wall. But the question is: why doesn't the man go through the wall? The man putting force to the wall is the action force and the wall not breaking and staying still is the reaction force given by the wall to the man. It does not move because the wall is giving the same amount of of force that the man gave the wall.

This first newton law is also known as the law of Inertia. It's known as the law of inertia because inertia is when the object is either at rest or in motion at a constant speed and direction. This law of motion is when an object in motion can stay in motion at the same speed and direction until an external force is applied. Or, an object can stay at rest until an external force is applied. The meaning of inertia is what the first newton law is about.

What is inertia? Inertia is when an object is either at rest or in motion at a constant speed and direction. The car above is at rest. The photo shows the first newton law being applied. When the man applies force to the car after the car being at rest, the car will no longer be at rest. The force that the man is applying to the car is the external force that will cause the object to no longer be at rest, but in motion. The car will now be in motion until an external force stops it.
The second law of motion mostly depends on the mass of the object to see how much force will be needed to be applied in order to accelerate. So the greater the mass of the object that is being accelerated, the greater amount of force will be needed. The equation for this law is: Force= Mass times Acceleration. That is why we need to know the mass and how much we want to accelerate to know how much force to put on an object.
