Kinetic and Potential Energy Flashcards
1
Q
Kinetic Energy
A
The energy of motion.
Examples: Sound, electrical, thermal, radiant (light)
2
Q
Potential Energy
A
Stored Energy
Examples: Elastic, nuclear, chemical
3
Q
Mechanical energy
A
The total amount of potential and kinetic energy in a system
4
Q
Kinetic Energy Equation
A
KE=1/2 mv2
m=mass
v=velocity
5
Q
Gravitational Potential Energy Equation
A
PE=mgh
m=mass
g= gravity (9.8 m/s on earth)
h=height
6
Q
Friction
A
The resistance to motion when two objects rub against each other, the force that changes kinetic energy into thermal energy
example: Rubbing your hands together
7
Q
Mass
A
the amount of matter an object has
8
Q
Velocity
A
How fast an object is going
