Things that Move, by Chris Young
In this Smore presentation I'm providing my Inclined Planes and Pulleys Around You assignment and my Flipped Video.
pulley on a crane
The pulleys on this crane help make lifting something easier by subtracting the of amount of force on the arm.
pulley for my Dad's bike
The pulleys here are lifting my Dad's bike so that they are not taking up the garage floor space.
plane
the plane i'm going down isn't very steep so I can lift things up it onto the parking lot easier than using stairs
This is a pulley that works with my garage door. It makes lifting the heavy door easier because it splits up the force needed into pulling horizontally AND vertically.
Newton's First Law
An object at motion will tend to stay in motion, and an object at rest will tend to stay at rest unless acted upon by an equal and opposite force.

Newton's Second Law
Force = Mass * Acceleration. Something with more mass requires more force to get it started and stopped, like comparing a train to a car.

Newton's Third Law
For every action there is an equal and opposite reaction.
