physics test, w p e
work power energy
Question | Answer |
---|---|
work formula | w= f-d; m-a-d |
velocity formula | v= x/t |
accerleration formula | a= v/t |
power formula | P= w/t ; f-d/t ; m-a-d/t |
momentum formula | p= m-v |
potential energy formula | pe= m-g-h |
kinetic energy formula | ke= 1/2 (m)(v)^2 |
mechanical energy | potential and kinetic energy |
energy formula | e= mc^2 |
inertia | resistance of an object to move (pushing on wall) |
force is____ of change | agent |
if potential energy is 0% kinetice = | 100% |
if an object doesnt move are you doing any work? | noooo!!! |
four forces | strong, weak, electromagnetic, gravity |
go from displacement to power | x. v=x/t a=v/t f=ma w=mad P=w/t |
