Key Questions:

1. What energy changes are involved when an object is projected upwards?
   • When an object is projected upwards gravitational potential Energy will increase, thermal Energy will increase due to friction, which will cause the kinetic Energy to decrease.
2. What is the equation for elastic potential energy?
   • The equation for elastic potential Energy is elastic potential Energy = 0.5 x spring constant x extension^2
3. What equation links g.p.e., height, mass and gravitational field strength?
   • Gravitational potential Energy = height x mass x gravitational field strength
4. What equation is used to calculate kinetic energy of a moving object?
   • The kinetic Energy of a moving object can be calculated using the equation: kinetic Energy = 0.5 x mass x speed^2
5. What is the equation for gravitational potential energy gained by an object raised above ground level?
   • The equation for gravitation potential Energy gained by an object above ground level is G.P.E = mass x gravitational field strength x height
6. In all system changes, what happens to energy?
   • In all system changes Energy is dissipated, so that it is stored in less useful ways. This Energy is often described as being 'wasted'.
