Energy Transfers Part 1 (F)

Which energy store is a store of movement energy?

• Thermal Energy
• Chemical Energy
• Kinetic Energy
• Potential Energy

Which energy store is based on objects being stretched and squeezed?

• Thermal Energy
• Chemical Energy
• Elastic Potential Energy
• Gravitational Potential Energy

What energy store is based on the height an object is at?

• Kinetic Energy
• Thermal Energy
• Gravitational Potential Energy
• Chemical Energy

Which energy store is based on the temperature of a substance?

• Chemical Energy
• Kinetic Energy
• Thermal Energy
• Potential Energy

Which energy store is based on opposite charges interacting?

• Kinetic Energy
• Potential Energy
• Thermal Energy
• Electrostatic Energy

Which is the principle of conservation of energy?

• Energy cannot be changed to different types but can be lost and gained

• Energy cannot be created or destroyed only transferred between stores

• Energy can be wasted and be created as a useful store but cannot be destroyed

• Energy can only be destroyed when wasted, it can be created and changed into different stores

Which is the correct equation for efficiency?

• = Useful Energy In / Total Energy Out

• = Useful Energy out / Wasted Energy Out

• = Useful energy Out / Total energy in

• = Useful Energy in / Total Energy in

Which method reduces energy loss between moving objects?

• Lubrication

• Insulation

• Defrictionisation

• Galvanisation

Which method reduces energy loss by stopping heat escaping?

• Convection

• Conduction

• Radiation

• Insulation

Renewable means ...

• Something that can be used again
• Something that will not run out or can be recreated within a decent time span

• Something that is non-renewable
• Something that is finite
