Chapter 5 - Work, Energy And Power Flashcards
1
Q
Formula:
Work Done
A
Work = Force x Distance
2
Q
Factors involved in Work
A
Size of force - bigger force = more work
Distance moved - further distance = more work
3
Q
Formula:
Work in gases
A
Work = pressure x change in volume
4
Q
Formula:
GPE
A
GPE = mass x gravity x height
5
Q
Formula:
Kinetic Energy
A
KE = 1/2 mass x velocity^2
6
Q
Define Principle of conservation energy
A
Energy cannot be destroyed or created. It can only be converted from one form to another
7
Q
Formula:
Power
A
Power = Work / time
OR
Power = Force x velocity
8
Q
Define Watt
A
A watt is the rate of the transfer of energy of one joule per second
