3. Kinetic Energy _______
When we do work on an object, energy is transferred into the system
When the object gains energy, it begins to move
If you do work on a car by pushing it, it gains kinetic energy and begins to move

5. Work-Energy Theorem
The total work done on an object equals the change in the object’s kinetic energy, provided there is no change in any other form of energy (for example, gravitational potential energy).
We can summarize …………..

6. Check Your Understanding
What total work, in megajoules (106), is required to cause a cargo plane of mass x 105 kg to increase its speed in level flight from 105 m/s to 185 m/s?

8. Gravitational Potential Energy
_________
The potential energy at a height “h” above that point is equal to the work which was required to lift the object to that height.

10. Things to keep in mind
ΔEg = the change in potential energy from one height to another
ΔEg is the change in gravitational potential energy, in joules; m is the mass, in kilograms; g is the …………..

11. Energy is Conserved Work is done…………..
Once no more Work is applied, the object stops moving up and Ek = 0. The energy from Ek is completely converted to Eg at its peak
