Energy Basics
The unit of measurement for energy.
What are joules?
Energy stored in bonds between atoms and molecules?
What is chemical energy?
What happens to the potential energy of a ball as it falls from a height, and what type of energy does it gain?
The potential energy decreases as it falls and kinetic energy decreases.
What type of kinetic energy is associated with the vibration of particles in a material or medium which special receptors in your ears pick up?
What is sound energy?
Give an example of an object with high potential energy.
A ball at the top of a hill.
This is what energy has the ability to do.
What is work?
What is potential energy?
What happens to the energy of a moving care when the brakes are applied to stop it?
Kinetic energy is converted to thermal energy through friction?
What type of kinetic energy is produced by the movement of charged particles, such as electrons?
What is electric energy?
What type of potential energy is stored in materials like rubber bands when they are stretched or a spring is compressed?
What is Elastic Energy?
The formula for calculating kinetic energy?
What is 1/2 x mass x velocity2 (1/2mv2)?
Energy produced by the flow of electric charges.
What is electrical energy?
In a flashlight, what type of energy transformation occurs to produce light?
Chemical energy from the batteries is transformed into electrical energy, which is then transformed into light energy.
What type of kinetic energy is carried by waves, including visible light and UV waves?
What is radiant/electromagnetic energy?
What type of potential energy is stored in the nucleus of an atom?
What is nuclear energy?
The formula for calculating potential energy due to gravity.
Energy associated with the mass, composition, and temperature of an object?
What is thermal energy?
Explain how a hydroelectric dam converts potential energy into electrical energy.
The dam stores water at a higher elevation, creating gravitational potential energy. When the water flows downhill, it turns turbines, which generate electrical energy.
What type of kinetic energy is associated with the random motion of tiny particles in matter, resulting in temperature?
What is thermal energy?
What type of potential energy is associated with the position of objects above the Earth's surface?
What is gravitational potential energy?
The two factors that affect how much work is done on an object
What is force and distance?
Energy that is produced by trillions of celestial objects in the night sky.
What is radiant/electromagnetic energy?
What type of energy transformation occurs in a microwave oven when it heats food?
Electrical energy is transformed into electromagnetic energy and then thermal energy, heating the food.
This factor has the most effect on how much kinetic energy an object has.
What is the velocity/speed of an object?
What type of potential energy is stored in the bonds between atoms and molecules?
What is chemical potential energy?
