Isaac Newton's Three Laws of Motion; By Maiya Saucedo
I wonder how things move and what causes them to stop and go.
Have you heard of Newton's three laws?
Let me explain!
Newton's first law is an object at rest will stay at rest, and an object in motion will stay in motion, unless acted in by an unbalanced force. As you can see, this ferris wheel keeps its same velocity because there is no unbalanced force stoping it.
I heard something about inertia, what is that?
Inertia is the property of an object to refrain from motion. Forces create these motions. Objects with more mass have more inertia.
By the way, mass is measured in grams, weight is measured in Newtons, and the net force of an object is all the forces combined.
Aren't mass and weight the same thing?
No! Never mix those up! Mass is matter in an object and weight is gravity acting on mass. Anyways, let's go.
Isn't accerlerating just speeding up?
Ugh! This car is so slow!
We are accelerating!
No, actually acceleration is change in speed and/or direction
