In our video, we will be demonstrating Newton's Laws and how they apply to cars. We will test each law and explain our data.

Newton's Laws may seem like a Physics I topic, but they are very relevant to Physics II as well. In Physics II, you can expect to hear these laws pertaining to space (with gravity and planetary motion). However, in this video we will be talking about them in detail relating to cars.

Newton's First Law of Motion states that," An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same velocity unless acted on by an unbalanced force." Usually, this law is referred to as inertia.

To demonstrate this law, we will show how my car does not stop unless it is acted on by the brakes.

The reason my car decelerates over time is because there are Earthly forces acting upon it. Such as gravity, friction, and wind resistance.

Since there are two perspectives to this law, we will put my car in neutral as well, to show that it will not move unless acted on by the engine.

Inertia is also shown when you forget to wear your seatbelt. There is no unbalanced force to slow you down so you fly forward through the windshield.

Newton's Second Law of Motion states that," A body acted on by a force will accelerate so that force equals mass times acceleration."






This statement can be written as an equation as such: F=ma.






To test this, we will find the acceleration and masses of our cars and calculate the force exerted on them.






This force is known as torque in the automotive world. More torque is needed as the mass of a vehicle is increased, or when greater acceleration is desired.






Calculate the acceleration and determine the weight of my car from online sources. Then find the force and convert to Newton's. Compare the results.






Newton's Third Law of Motion states that," For every action there is an equal and opposite reaction."






This is shown when cars collide with each other or objects. We will not be demonstrating this law ourselves, but we can show you a few videos to give you some perspective.






In case of a collision into a pole, the force exerted when the car crashes into the pole would result in the pole exerting the same amount of force on the fender, and smash it. The force can be found with Newton's second law of motion, force equals mass times acceleration.
