Newton's Three Laws of Motion

   Hey guys, I'm back with another post! This week, we'll be discussing Newton's Three Laws of Motion. And I think it's safe to say that we've been discussing Newton quite a bit lately. Yup, he's done a lot of stuff, and now we're doomed to talk about it every week -__-. Yeah, it can be tedious...but that's okay, I guess (not really)!

Newton's First Law Of Motion
 An object at rest stays at rest, and an object in motion stays in motion at a constant speed and in the same direction until it is acted upon by an external force. For example, if a ball is sitting on the sidewalk, it will remain that way until it is moved. Now, say someone wanders up and kicks the ball. The ball will roll at the same speed and in the same direction until an external force halts its movement(s); like it runs into a wall, or someone else kicks it in a different direction and changes its velocity.

Newton's Second Law of Motion
  When a force acts on a mass, it produces acceleration. The more mass an object has, the more force that needs to be applied to accelerate it. For example, it will take you a lot less force to move a soccer ball by kicking it than it would to kick a brick wall. You use the formula F(force)= m(mass) * a(acceleration).









(Newton's Second Law= Mo'e force, Mo'e acceleration)



Newton's Third Law of Motion
  For every action there is an equal and opposite reaction. Think of Newton's Cradle; when you let one ball fall it will hit the one next to it. Then the force will cause the ball all the way on the end of the row to swing. The ball at the other end will then swing back and hit the one next to it. The two balls at the end will continue to swing back and forth for a while.

 

Hope you guys enjoyed!

 

I'll be back soon!
