Standard Science Primary 6 Energy

A ball is dropped from a height. Which of the following correctly describes the energy conversion as the ball falls towards the ground?

A Kinetic Energy → Potential Energy
B Potential Energy → Kinetic Energy + Heat Energy
C Chemical Energy → Potential Energy
D Kinetic Energy → Sound Energy only

Worked Solution

Step 1: At the height, the ball has Gravitational Potential Energy. Step 2: As it falls, it loses height and gains speed (Kinetic Energy). Step 3: Some energy is converted to heat and sound due to air resistance. Step 4: The primary conversion is Potential to Kinetic + Heat/Sound.

Correct answer: Potential Energy → Kinetic Energy + Heat Energy
