Gr.10 T4 Physics Flashcards
1
Q
What is gravitational potential energy?
A
The energy that an object has due to its position in a gravitational field relative to a reference point.
2
Q
What is the formula for gravitational potential energy? (On data sheet)
A
E = mgh
P
3
Q
What is kinetic energy?
A
The energy an object has as a result of its motion.
4
Q
What 2 things is kinetic energy directly proportional to?
A
2 mass and (speed)
5
Q
What is mechanical energy?
A
the total amount of potential energy plus kinetic energy in a system
6
Q
What is the Law of Conservation of Energy
A
Energy cannot be created or destroyed. It can only be transformed from one form into another.
7
Q
What is the Principle of Conservation of Mechanical Energy?
A
In the absence of dissipative forces the total mechanical energy in a system is conserved.
