Primary 6 Science: Energy Conversion Practice
Real Primary 6 Science questions on Energy Conversion, pulled directly from the Olibits question bank — the same questions a child would actually see, not separately written for this page.

Real Energy Conversion practice questions
You stretch a rubber band between your fingers, ready to flick it across the room. What form of energy is stored in the stretched rubber band?
Kinetic energy
Sound energy
Potential energy ✓
Light energy
A stretched rubber band stores potential energy due to its changed shape, which converts into kinetic energy when released.
A family gathers to watch a television show together, seeing pictures and hearing sound from the screen. What forms of energy does the television mainly convert electrical energy into?
Heat energy and chemical energy
Light energy and sound energy ✓
Kinetic energy and potential energy
Chemical energy and potential energy
A television produces a picture and sound, converting electrical energy mainly into light energy and sound energy.
A student holds a ball high above their head, ready to throw it. What form of energy does the ball have due to its high position?
Electrical energy
Sound energy
Kinetic energy
Potential energy ✓
An object has potential energy when held in a raised position from which it can fall or move, such as being held up high.
A football lies still on the grass. After it is kicked, it rolls quickly across the field. What can we correctly say about the football's kinetic energy?
The football has the same kinetic energy whether it is still or rolling
The football has kinetic energy only while it is rolling, because kinetic energy is the energy of movement ✓
The football has more kinetic energy while lying still
The football loses all of its energy the moment it is kicked
Kinetic energy is the energy of movement; a still football has none, but once kicked and rolling, it has kinetic energy.
