# Laws Of Motions

# Newton's first law of motion

By Emily Mcfarling #NewtonsLaws #Kettner

Newton's first law is: **That an object in motion will stay in motion and an object at rest will stay at rest untell acted on by an unbalanced force.**

One example is: W*hen a pilot turns the plane and the passengers will want to stay the same direction so it feels like they got pulled the opposite way.*

Last example is: *When a coffee mug gets left on a car and then the driver speeds away, the cup will want to stay at rest so it will slide off the back of the car.*

# Newton's second law of motion

Newton's second law states: **The force of an object is equal to its mass times its acceleration.**

One example: *That pushing a 10lb ball as hard as you can, then pushing a 5lb ball as hard as you can. The 10lb ball would accelerate less then the 5lb ball because the 10lb ball has more mass.*

Last example: *Pushing a ball, the velocity goes from 0 to how hard you push the ball. Newton's second law also states that if it gets twice the mass it accelerates half as muc*h.

# Newton's third law of motion

Newton's third law states that: **Every action there is an equal and opposite reaction**.

One example is*: You find it hard to walk on a slippery surface because the only way you can walk forward id for your foot to push backward on the surface of the ground.*

Last example: *A rocket can be launched into space because the hot gases from it are being propelled downward from the rocket,causing the rocket to move upward with equal farce. *
