Questions & Step-by-Step Solutions
Which of the following is the correct expression for gravitational potential energy (U) of an object of mass m at a height h? (2020)
Step 1: Understand that gravitational potential energy (U) is the energy an object has due to its position in a gravitational field.
Step 2: Identify the variables involved: 'm' is the mass of the object, 'g' is the acceleration due to gravity, and 'h' is the height above a reference point.
Step 3: Recognize that gravitational potential energy increases with height, meaning the higher the object is, the more potential energy it has.
Step 4: The formula for gravitational potential energy is derived from the relationship between these variables, which is U = mgh.
