Potential Energy
A block of mass 2 kg is raised to a height of 10 m above the ground. What is the increase in its potential energy? (g = 10 m/s²)
Select the correct option:
Solution
200 J
- Definition: The gravitational potential energy of a body near the Earth's surface is given by its height relative to a reference level.
- Formula: U=mgh.
- Identify Data:
- m=2 kg.
- g=10 m/s2.
- h=10 m.
- Calculation: U=2×10×10=200 J.
- Result: The increase in potential energy is 200 Joules.
