When a 6kg mass is lifted from ground to a height of 12 meters,the gravitational potential energy of the mass increases. Calculate how much will be the increase?
m * g * h
To calculate the increase in gravitational potential energy, you need to use the formula:
ΔPE = mgh
Where:
ΔPE represents the change in gravitational potential energy,
m is the mass of the object (6 kg),
g is the acceleration due to gravity (approximately 9.8 m/s^2),
h is the height (12 meters).
Substituting the given values into the formula:
ΔPE = (6 kg)(9.8 m/s^2)(12 m)
To find the numerical value, simply multiply:
ΔPE = 705.6 joules
Therefore, the increase in gravitational potential energy when the 6 kg mass is lifted to a height of 12 meters is 705.6 joules.
