Mechanical EnergyMechanical energy the sum of the kinetic and potential energies

Em = Ep + Ek

Law of Conservation of EnergyEnergy cannot be created or destroyed, only transferred.Ep transferred into Ek when an object moves

Energy transformed from one type to another, BUT the TOTAL AMOUNT OF ENERGY never changes. Amount of mechanical Energy is constant!

To make our life simple, we will assume that no energy is lost to heat/friction/air resistance etc (even though in real life it is )

Example 6.7

A 1.5kg block is dropped off a cliff, 30.0m above the surface of the lake. What is the velocity just before it hit the water?Remember that work is change in Energy!

Lets watch a highly questionable activity and link it to Energy!DONT ATTEMPT THIS AT HOME!

An average force of 100.0N is needed to pull a bow string back 0.500m. The bow is aimed straight up in the air and released.

What is the work done to pull the bow string back?How much elastic potential energy is stored in the bow?How much kinetic energy does the arrow have just as it leaves from the bow?What will be the Ek and EP at the arrows highest position?WHAT IS THE RELATIONSHIP BETWEEN W, Ep & Ek???
