Energy Topic Recap Quiz for Easter

What is the fundamental principle of energy discussed in the video?

• Energy can be created and destroyed

• Energy is only important in physics

• Energy can be stored indefinitely without any transfer

• Energy is only ever transferred between different forms and objects

Which type of energy is associated with the movement or motion of an object?

• Thermal energy

• Kinetic energy

• Gravitational potential energy

• Elastic potential energy

What does the term 'work done' refer to?

• The energy required to heat an object

• The amount of energy stored in an object's energy stools

• The transfer of energy to an object

• The total energy within a closed system

What type of energy is stored in chemical bonds?

• Magnetic energy

• Chemical energy

• Thermal energy

• Kinetic energy

How can energy be transferred between different forms?

• Mechanically, electrically, by heating, or by radiation

• Only mechanically

• Only electrically

• Only by heating

What distinguishes an open system from a closed system in terms of energy?

• A closed system frequently exchanges energy with its surroundings

• An open system can lose or gain energy as it interacts with the outside world

• A closed system allows energy to enter or leave

• An open system cannot lose or gain energy

What happens to the electrical energy from the plug socket when a kettle is turned on?

• It is transferred to the thermal energy store of the kettle's heating element

• It is destroyed

• It remains as electrical energy

• It is created

What is mechanical work done?

• The energy required to overcome the resistance in wires

• The process of charging a battery

• Using a force to move an object

• The transfer of energy by heating

What type of energy does a stretched spring store?

• Elastic potential energy

• Kinetic energy

• Gravitational potential energy

• Chemical energy

What is the result of applying brakes to stop a train according to the energy transfer described?

• The train's kinetic energy is transferred to the thermal energy stores of the surroundings

• No energy transfer occurs

• The train generates more kinetic energy

• The train's chemical energy is increased
