Newton's Laws of Motion
By: Cole Hubertus and Danny Driscoll
Newton's 1st Law
This means that an object will not stop moving, until a different force is applied to it.
For example, a car will experience this law if it suddenly collides with a brick wall while at a constant velocity.
Newton's Second Law
This could also work in the opposite such as Mass = Force/Acceleration and Acceleration = Force/Mass.
The original equation proves that more force applied to an object would make it move faster and less force on the same object will result in a slower speed.
Word Problem: A car with a mass 200 kg is moving with an acceleration of 5 m/sec2.
You would multiple 200 by 5 and get an answer of 1000 Newtons.
Below is a video of a strong Russian man pushing a car. See if you can figure out the force he's appealing to the car:
Newton's Third Law
For every force there is an equal and opposite force, for every action there is an action and an equal and opposite reaction.
This means that there is a reaction for every action that takes place on earth. If something is pushed down, something else must be pulled up.
If you jump off of a diving board for instance. As you push down, an opposite force of the board pushing up will occur. Causing you to jump into the pool.
Vocab Words to Know:
Acceleration: A change in velocity over a given amount of time.
Mass: The amount of matter in an object.
Inertia: An object’s tendency to resists a change in motion.
