Energy

Are region of space for an object experiences a force because of its mass

Force of attraction at bodies have for each other because of the mass

Ep Energy and object has by virtue of its position and that gravitational field gravitational potential energy is the energy of an object because of its position in a gravitational field relative to a reference point

Ep =mgh Gravitational potential energy equals mass times nine, eight times height above reference point Measured in Joules is the scaler quantity and the amount of energy transferred when one Newton of force acts on an object for 1 m

Energy and object has by virtue of its position state or shape it is stored energy it takes many forms such as chemical electrical and radiated

Ek The energy than object has as a result of its motion

Ek = 1/2 m(v)square Kinetic energy is equal to half mass times magnitude of the velocity squared It is measured in Joules

Energy is never created or destroyed but can really be transferred from one form to another

Em The sun of the car needed energy and gravitational potential energy of an object it remains constant because they transfers between kinetic and gravitational potential energy

Em=Ek +Ep Em =1/2 m(v)square +mgh Ek1+Ep1=Ek2+Ep2 It is measured in Joules

In the absence of air resistance and friction mechanical energy of an object moving in its gravitational field is constant Ek1+Ep1=Ek2+Ep2
