MYP 1, Grade 6, Energy Quiz

Which of the following is NOT a form of energy?

• Chemical
• Gravitational
• Sound
• Absorptive

A high object has more of which type of energy compared to a low object?

• Thermal Energy
• Kinetic Energy
• Gravitational Potential Energy
• Elastic Energy

According to the law of conservation of energy:

• Energy can be created and destroyed.
• Energy can only be transferred from one form to another.
• Energy is always increasing in the universe.
• Energy can be transferred but not measured.

Energy is measured in:

• Watts, W

• Joules, J

• Calories

• Volts, V

Which type of energy does a trampoline primarily use to lift someone into the air?

• Nuclear → Kinetic
• Gravitational → Elastic
• Elastic → Kinetic → Gravitational
• Chemical → Thermal → Sound

A fast-moving object has more of which type of energy compared to a slow-moving object?

• Thermal Energy
• Gravitational Potential Energy
• Kinetic Energy
• Sound Energy

Which energy transformation occurs when friction slows down a moving car?

• Kinetic → Gravitational Potential
• Chemical → Kinetic
• Thermal → Gravitational Potential
• Kinetic → Thermal

What type of energy is produced when a battery-powered torch (flashlight) is turned on, and what is the flow of energy?

• Chemical → Electrical → Gravitational

• Chemical → Electrical → Light

• Light → Kinetic → Electrical

• Sound → Thermal → Electrical

In which situation is thermal energy transferred to kinetic energy?

• A speaker producing sound

• A car accelerating on the road

• A hot pan heating a pot of water

• Friction between car wheels and the road

Answer explanation

A car accelerating on the road converts thermal energy from the engine (the fuel lights up and creates mini exploisions) into kinetic energy, increasing its speed. This is a direct transfer of energy forms, unlike the other options which do not involve this specific conversion.
