What are the formula for kinetic and potential energy?

Question

Its for my homework.

Answer 1

If an object of mass m is moving with speed v, where v is very small compared to speed of light, then

kinetic energy = 1/2 * mv^2

There are many kinds of potential energy. Which one are you talking about? I am giving formulas for two.

If a spring with force constant k is compressed or elongated by length x, then potential energy stored in the spring = 1/2*k*x^2

If an object of mass m is kept at height h above the surface of the Earth, where h is so small that acceleration due to gravity g can be assumed to be constant, then

gravitational potential energy = mgh

Here the gravitational potential energy at the surface of the Earth is taken as zero.

Answer 2

KE=1/2mv^2

PE=mgh

m=mass

g=force of gravity

h=height

v=velocity

make it a good day

Answer 3

Kinetic Energy = (1/2)mv²

and

Potential Energy = mgh

where

m = mass of the object

v = velocity of the object

g = acceleration due to gravity [ = 9.8 m/s² ]

h = height of the object from earth surface.
