Question

When we have been given mass , height and Acceleration due to gravity and are asked to find kinetic energy..... how to find ????

Answer 1

For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m2 / s2.

Answer 2

P.E = mgh
where a m = mass
g = acceleration due to gravity
h = height

P.E = K.E
This means that the potential energy of the object changes to Kinetic energy and kinetic energy will be the same as the unit of Potential energy.

K.E = mgh
