energy calculations Flashcards
1
Q
what is gravitational potential energy
A
energy that could potentially do work due to an objects position above ground
2
Q
what is the equation for GPE+ units
A
GPE= mgh
gpe(joules)=m(kilo) x 9.8 m/s/s x h(meters)
3
Q
what is kinetic energy
A
energy due to an objects motion
4
Q
what is the equation for KE +units
A
KE= .5mv^2
Ke(joules)=.5x m(kg) x v(m/s)^2
5
Q
what is mechanical energy
A
The amount of work an object can accomplish due to a combination of
the object’s kinetic AND potential energies.
6
Q
what is the equation for mechanical energy
A
ME=KE+PE
