MATH STUFF for Work and Energy
Term | Definition |
---|---|
K | unit for temperature (Kelvin) |
Q = m(Tf - Ti)C | equation for change in thermal energy [thermal energy = mass(final temperature - initial temperature) x specific heat] |
w = fd | equation for work (work = force x distance) |
J | unit for work (Joule) |
e = Wout/Win x 100 | equation for efficiency (efficiency = work out divided by work in x 100) |
KE = 0.5mv^2 | equation for Kinetic Energy (Kinetic Energy = 0.5 x mass x velocity squared) |
GPE = mgh | equation for gravitation potential energy (gravitational potential energy = mass x gravity x height) |
p = E/t | equation for power (power = energy divided by time) |
W | unit for power (Watt) |
