What is the formula for calculating the potential energy of an object at height h?
PE = mgh
PE = 1/2 mv²
PE = mv²
PE = mgh²
The potential energy of an object at height h is calculated using the formula PE = mgh, where m is mass, g is gravitational acceleration, and h is height.

Q: What is the formula for calculating the potential energy of an object at height h?
Solution: The potential energy of an object at height h is calculated using the formula PE = mgh, where m is mass, g is gravitational acceleration, and h is height.
Steps: 5
Step 1: Identify the mass (m) of the object. This is how much the object weighs.
Step 2: Determine the height (h) of the object above the ground. This is how high the object is.
Step 3: Know the value of gravitational acceleration (g). On Earth, this is approximately 9.8 m/s².
Step 4: Use the formula PE = mgh. This means you multiply the mass (m) by the gravitational acceleration (g) and then by the height (h).
Step 5: Calculate the result to find the potential energy (PE) of the object.
