Q: How does the gravitational potential energy of an object change when it is lifted to a height 'h' above the ground?
Solution: The gravitational potential energy increases as the object is lifted to a height 'h' above the ground.
Steps: 5
Step 1: Understand what gravitational potential energy is. It is the energy an object has because of its position in a gravitational field.
Step 2: Know that the formula for gravitational potential energy (PE) is PE = m * g * h, where 'm' is mass, 'g' is the acceleration due to gravity, and 'h' is the height above the ground.
Step 3: When you lift an object to a height 'h', you are increasing the value of 'h' in the formula.
Step 4: As 'h' increases, the gravitational potential energy (PE) also increases because you are multiplying a constant (mass and gravity) by a larger height.
Step 5: Therefore, lifting the object higher means it has more gravitational potential energy.
