What is kinetic energy?
If you imagine a drop of water about to fall down a waterfall, at the top of the waterfall the drop of water has this kind of energy.
What is potential energy?
Simple machines are designed make work easier. They create a ___________ advantage.
What is mechanical?
The result when potential energy and kinetic energy are added (used together)
What is mechanical energy.
This type of energy is present in a glass of water on a table.
What is potential energy?
The formula for calculating work.
What is work = force x distance?
Units for amount of Energy/work.
What is Joules?
