If a 10 kg object is dropped from a height of 5 m, what is the potential energy

If a 10 kg object is dropped from a height of 5 m, what is the potential energy at that height?

If a 10 kg object is dropped from a height of 5 m, what is the potential energy at that height?

Correct Answer: 490 J

Step 1: Identify the mass of the object. In this case, the mass (m) is 10 kg.
Step 2: Identify the height from which the object is dropped. The height (h) is 5 m.
Step 3: Identify the acceleration due to gravity. The value of g is approximately 9.8 m/s².
Step 4: Use the formula for potential energy, which is PE = mgh.
Step 5: Substitute the values into the formula: PE = 10 kg × 9.8 m/s² × 5 m.
Step 6: Calculate the result: 10 × 9.8 × 5 = 490 J.
Step 7: Conclude that the potential energy at that height is 490 Joules.

Potential Energy – Potential energy is the energy stored in an object due to its position in a gravitational field, calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
