What is the definition of energy?
Energy is the capacity to do work or produce change.
Energy is a type of matter.
Energy is a form of heat.
Energy is the speed of light.
Name two forms of energy.
Kinetic energy, Potential energy
Thermal energy
Nuclear energy
Chemical energy
What is the law of conservation of energy?
Energy cannot be created or destroyed, only transformed.
Energy can only be created from matter.
Energy can be created and destroyed.
Energy is always lost in transformations.
How does kinetic energy differ from potential energy?
Kinetic energy can be stored in a compressed spring.
Kinetic energy is always greater than potential energy.
Kinetic energy differs from potential energy in that kinetic energy is associated with motion, whereas potential energy is associated with position or configuration.
Potential energy is only found in moving objects.
Give an example of a situation where energy is transformed.
A battery storing energy without any discharge.
A light bulb converting electrical energy into light energy.
A car converting fuel into kinetic energy.
A solar panel absorbing sunlight without generating electricity.
What unit is used to measure energy?
meters
liters
joules
grams
Explain how energy can be transferred from one object to another.
Energy can be transferred through conduction, convection, radiation, and mechanical work.
Energy transfer is impossible between solid objects.
Energy can only be transferred through chemical reactions.
Energy can only be stored, not transferred.
What is renewable energy? Give two examples.
Solar energy and wind energy.
Nuclear energy and geothermal energy
Hydroelectric energy and fossil fuels
Natural gas and coal energy
How does friction affect energy in a system?
Friction increases energy by converting thermal energy into mechanical energy.
Friction reduces energy in a system by converting mechanical energy into thermal energy.
Friction only affects potential energy, not mechanical energy.
Friction has no effect on energy in a system.
Describe the relationship between work and energy.
Energy cannot be transferred through work.
Work is the same as energy.
Work is the transfer of energy; doing work increases energy in an object, while energy transfer decreases it.
Doing work decreases the energy in an object.
