Questions & Step-by-Step Solutions
If the mass of an object is 10 kg and it is located at a point where the gravitational potential is -30 J/kg, what is the gravitational potential energy of the object?
Step 1: Identify the mass of the object. In this case, the mass (m) is 10 kg.
Step 2: Identify the gravitational potential (V) at the location of the object. Here, the gravitational potential is -30 J/kg.
Step 3: Use the formula for gravitational potential energy (U), which is U = m * V.
Step 4: Substitute the values into the formula: U = 10 kg * (-30 J/kg).
Step 5: Calculate the result: U = -300 J.
Gravitational Potential Energy – Gravitational potential energy (U) is calculated using the formula U = m * V, where m is the mass of the object and V is the gravitational potential.
Gravitational Potential – Gravitational potential (V) is the potential energy per unit mass at a point in a gravitational field, expressed in joules per kilogram (J/kg).
