Mechanical Energy
1) This force is when two objects rub against each other
2) What energy is always produced because of this force?
1) friction
2) thermal energy
What is the formula for work?
Work = Force x Distance

Radiant Energy
Write out the definition of Energy.
The ability to do work.
When a force applied to an object moves the object in the Same/Opposite/Perpendicular direction as the force, then work is done.
SAME
When a firecracker explodes, the chemical energy is transformed into what 3 types of energy?
1) light 2) thermal/heat 3) sound
What is the relationship between potential & kinetic energy?
The more potential energy, the more possible kinetic energy
Energy of an object due to the kinetic energy of it's atoms.
Thermal Energy
Experienced in a loop or a circle on a roller coaster
Centripetal force
Is WORK done if there is NO movement?
No!
Kinetic energy is changed to thermal energy while a car is driving, because of what?
Friction
True or False: The faster something is, the more potential energy it has.
False - The faster something is, the more KINETIC energy is has.
Energy transferred through a medium by a longitudinal wave.
Sound Energy
While riding a roller coaster, this force allows the coaster to keep moving until an opposing force stops it.
Inertia
You exert 20N of force on a soccer ball which travels 60m. Calculate how much work is done.
1200 Joules
