Questions & Step-by-Step Solutions
If the mass of an object is 5 kg and it is at a height of 10 m above the ground, what is its gravitational potential energy?
Step 1: Identify the mass of the object. In this case, the mass (m) is 5 kg.
Step 2: Identify the height above the ground. Here, the height (h) is 10 m.
Step 3: Identify the acceleration due to gravity (g). The standard value for g is approximately 10 m/s².
Step 4: Use the formula for gravitational potential energy, which is U = mgh.
Step 5: Substitute the values into the formula: U = 5 kg * 10 m/s² * 10 m.
Step 6: Calculate the result: U = 5 * 10 * 10 = 500 J.
Gravitational Potential Energy – The energy an object possesses due to its position in a gravitational field, calculated using the formula U = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
