A 5 kg object is lifted to a height of 2 m above the ground. Calculate its gravitational potential energy.
where m is the mass of the object and v is its velocity. A 5 kg object is lifted to a height of 2 m above the ground
KE = ½ × m × v^2 = ½ × 2 kg × (4 m/s)^2 = 16 J A 5 kg object is lifted to a height of 2 m above the ground
GPE = m × g × h = 5 kg × 9.8 m/s^2 × 2 m = 98 J A 5 kg object is lifted to a height of 2 m above the ground
Solution:
Potential energy is the energy an object possesses due to its position or configuration. There are two main types of potential energy: gravitational potential energy and elastic potential energy.
Work done = m × g × h = 100 kg × 9.8 m/s^2 × 5 m = 4900 J
