... Total mechanical energy would be conserved and both blocks started with the same potential energy U = mgh and no kinetic energy. With friction present the energy lost due to friction is given by the work done by friction on the blocks Wnon-conservatice = −fk L = −(µk N) L = −(µk mg cosθ) h/sinθ = −( ...

Motion & Forces
... You don't always need to see something move to know that motion has taken place. A reference point is needed to determine the position of an object. Motion occurs when an object changes its position relative to a reference point. The motion of an object depends on the reference point that is chosen. ...

Newton`s Second Law I
... Inertia is a term used to measure the ability of an object to resist a change in its state of motion. An object with a lot of inertia takes a lot of force to start or stop; an object with a small amount of inertia requires a small amount of force to start or stop. The word “inertia” comes from the L ...

Newton`s Laws of Motion
... A heavy moving object has a greater amount of motion than a light object. The amount of motion/mass of a body is defined as momentum. Momentum is taken as the product of mass & velocity of a body. The unit of momentum is therefore kilograms x metres per second kg ms-1 or kg m/s For the same given fo ...
