Questions & Step-by-Step Solutions
A 5 kg object is lifted to a height of 10 m. What is the gravitational potential energy gained?
Step 1: Identify the mass of the object. In this case, the mass (m) is 5 kg.
Step 2: Identify the height to which the object is lifted. Here, the height (h) is 10 m.
Step 3: Identify the acceleration due to gravity (g). On Earth, g is approximately 10 m/s².
Step 4: Use the formula for gravitational potential energy (PE), which is PE = m * g * h.
Step 5: Substitute the values into the formula: PE = 5 kg * 10 m/s² * 10 m.
Step 6: Calculate the result: 5 * 10 * 10 = 500 J.
Step 7: Conclude that the gravitational potential energy gained is 500 Joules.
Gravitational Potential Energy – The energy an object possesses due to its position in a gravitational field, calculated using the formula PE = m * g * h, where m is mass, g is the acceleration due to gravity, and h is height.
