Standard Science Primary 6 Energy

Four balls of different masses are released from different heights. Which ball will have the GREATEST gravitational potential energy at the point of release?

A Ball R: 3kg at 4m
B Ball P: 2kg at 5m
C Ball Q: 1kg at 10m
D Ball S: 2kg at 10m

Worked Solution

Step 1: GPE depends on both mass and height (GPE = m * g * h). Step 2: Compare the products (mass * height). Step 3: P: 10, Q: 10, R: 12, S: 20. Step 4: Ball S has the highest value.

Correct answer: Ball S: 2kg at 10m
