2. Energy- is the ability to do work.
There are 2 main types of energy:
Kinetic and Potential.
● Kinetic energy-energy that it possesses due
to its motion.
● Potential energy- is energy stored in a
system of forcefully interacting physical
entities.
3. Kinetic Energy- energy that it possesses due to its motion..
Kinetic energy depends on the: mass & speed.
Mass- How heavy an object weighs.
Speed- How fast an object is.
Example: There are 2 cars, car1 weighs 1 ton and is going 30mph. Car2 weighs
1.5 ton and is going 29.1mph. If they were to hit each other which car would have
more kinetic energy? Answer: Car2, Because the mph is almost 30 and it will be more effective.

4. ● Potential Energy- is energy stored in a system of forcefully
interacting physical entities.
Potential energy depends on one thing:
If the object is still or
if there is no effect to an object.
Example: There are 2 cars, car1 weighs 1 ton and is going 30mph. Car2
weighs 1.5 ton and is going 29.1mph. If they were to hit each other which car
would have more potential energy? Answer: Car1, Because the other car will be effective to
car1. Move to review answer
