A 3 kg object is dropped from a height of 10 m. What is its potential energy at the top? (g = 9.8 m/s²)

A 3 kg object is dropped from a height of 10 m. What is its potential energy at the top? (g = 9.8 m/s²)

Step 1: Identify the mass of the object. In this case, the mass (m) is 3 kg.
Step 2: Identify the height from which the object is dropped. Here, the height (h) is 10 m.
Step 3: Identify the acceleration due to gravity. It is given as g = 9.8 m/s².
Step 4: Use the formula for potential energy (PE), which is PE = m × g × h.
Step 5: Substitute the values into the formula: PE = 3 kg × 9.8 m/s² × 10 m.
Step 6: Calculate the potential energy: 3 × 9.8 × 10 = 294 J.

Potential Energy – Potential energy is the energy stored in an object due to its position in a gravitational field, calculated using the formula PE = m × g × h.
