Standard Science Primary 6 Energy

A pendulum bob is released from Position X. At which point does the bob have the maximum kinetic energy?

A Halfway between X and Y
B At Position X (highest point)
C At Position Y (lowest point)
D When it stops swinging
Show Worked Solution

Worked Solution

Step 1: As the bob falls from X to Y, its gravitational potential energy is converted into kinetic energy. Step 2: At the lowest point (Y), its speed is highest, meaning kinetic energy is at its maximum. Step 3: As it rises again, kinetic energy converts back to potential energy.

Correct answer: At Position Y (lowest point)
