A 3 kg object is dropped from a height of 15 m. What is the potential energy at the top?

A 3 kg object is dropped from a height of 15 m. What is the potential energy at the top?

Step 1: Identify the mass of the object. In this case, the mass is 3 kg.
Step 2: Identify the height from which the object is dropped. Here, the height is 15 m.
Step 3: Identify the acceleration due to gravity (g). The value of g is approximately 9.8 m/s².
Step 4: Use the formula for potential energy, which is: Potential energy = mass × g × height.
Step 5: Substitute the values into the formula: Potential energy = 3 kg × 9.8 m/s² × 15 m.
Step 6: Calculate the potential energy: 3 × 9.8 × 15 = 441 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 = mass × gravity × height.
Gravitational Acceleration – The acceleration due to gravity (g) is approximately 9.8 m/s² near the Earth's surface.
