Calculate the energy possessed by an object of mass 10 kg when it is raised to a height of 5 m from the ground. Given: g = 9.8 m s-2.
490 J
To calculate the energy possessed by the object, we need to determine its gravitational potential energy (GPE). The formula for gravitational potential energy is:
GPE = m × g × h
Where:
- m is the mass of the object (in kilograms)
- g is the acceleration due to gravity (in meters per second squared)
- h is the height above the ground (in meters)
Given:
- m = 10 kg
- g = 9.8 m/s²
- h = 5 m
Substitute these values into the formula:
GPE = 10 kg × 9.8 m/s² × 5 m
GPE = 490 J
Therefore, the energy possessed by the object when it is raised to a height of 5 meters is 490 J.
