Potential and Kinetic
A student walking to lunch has this type of energy
Kinetic energy.
Energy caused by the flow of electrons creating electrical charges.
Electrical energy
The three types of heat transfer
Conduction, convection, and radiation
Give an example of electrical energy transforming to radiant (light) energy.
Various answers. Ex: lamp
A heavy vase on a table has this type of energy.
potential energy
The type of heat transfer that involves direct contact.
Conduction
Energy that travels through space, includes visible light, microwaves, and x-rays
Radiant (light) energy
Which object has more kinetic energy, a 2 kg ball rolling at 2 m/s or a 6 kg ball rolling at 2 m/s?
6kg ball
This type of energy is generated by movement -
Mechanical energy.
The type of heat transfer that comes from electromagnetic waves.
Radiation
True or false: gravitational potential energy depends on an object's height.
True
Which has more potential energy? A roller coaster at 50 meters above the ground or at 25 meters?
What is 50 meters above the ground?
Using a radio plugged into the wall.
Electrical energy -> sound energy
The type of heat transfer that involves currents due to the hotter fluid rising and the colder fluid sinking.
Convection
Amount of kinetic energy depends on these two things.
Mass and speed
Adding textbooks/height to a ramp increases this.
What is potential energy?
The sun is an example of these types of energy (two)
Thermal and light
A solar panel on the roof of a building used to heat and cool the building.
Electromagnetic (light) energy -> electrical energy -> heat energy
Heat always transfers from a _________ object to a _________ object.
Warmer to cooler
State the Law of Conservation of Energy.
Energy cannot be created or destroyed just transformed.
