It's mass (weight) and velocity (speed)
To calculate the mechanical energy of an object you must add its ______ and _____
Kinetic energy and potential energy
Mrs. LaMena pulls as hard as she can on a stuck door but it won't budge! Did she do any WORK?
No, because nothing changed/moved.
The light energy I see from my phone screen is powered by this energy that is stored in the battery
Chemical energy
This is the energy of motion

light energy to thermal energy
A 500 g ball and a 50 g ball are pushed off of the same shelf. Which will strike the ground with a higher kinetic energy?
The 500 g ball because it has more mass
True or False: Energy can be created and destroyed
I drop a ball and it bounces. This is because when it hits the floor it squishes slightly, giving it this kind of energy
Elastic potential energy
This is the primary source of energy we receive from the sun
If I ring a bell I am converting ______ energy to _______ energy
Kinetic energy to sound energy
