Q
Q: A 2 kg object is dropped from a height of 10 m. What is its potential energy at the top?
Solution:
Potential Energy = mass × g × height = 2 kg × 9.8 m/s² × 10 m = 196 J.
Steps: 6
Show Steps
Step 1: Identify the mass of the object. In this case, the mass is 2 kg.
Step 2: Identify the height from which the object is dropped. Here, the height is 10 m.
Step 3: Know the value of gravitational acceleration (g). It is approximately 9.8 m/s².
Step 4: Use the formula for potential energy: Potential Energy = mass × g × height.
Step 5: Substitute the values into the formula: Potential Energy = 2 kg × 9.8 m/s² × 10 m.
Step 6: Calculate the result: 2 × 9.8 × 10 = 196 J.
