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: When 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 much.

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.
