Forms of Energy
Energy stored because of an object's position or shape.
What is potential energy?
What energy moves from one object to another without changing type.
What is energy transfer?
A measure of the average kinetic energy of particles in a substance.
What is temperature?
Heat transfer that occurs through direct contact between particles.
What is conduction?
A material property that describes how easily heat moves through a substance.
What is thermal conductivity?
The energy of motion, such as a moving car or flowing water.
What is kinetic energy?
When energy changes from one form into another form.
What is energy transformation?
Which has more thermal energy: a large warm object or a small warm object at the same temperature.
What is the larger object?
Heat transfer caused by the movement of fluids like air or water.
What is convection?
Why metal pans cook food faster than wooden or plastic pans.
What is higher thermal conductivity?
Energy stored in bonds of food, fuel or batteries.
What is chemical energy?
Motion from a rolling bowling ball causes pins to scatter across the lane.
What is kinetic energy being transferred?
Why two containers at the same temperature can have different total thermal energy.
What is a difference in mass or number of particles?
Heat transfer that can occur through empty space.
What is radiation?
Why cities are often warmer than grassy areas nearby.
What is greater absorption of thermal energy.
The total energy of all the moving particles in a substance.
What is thermal energy?
what occurs when electrical energy in a heater becomes thermal energy.
What is energy transformation?
What happens to thermal energy when more of the same substance is added at the same temperature.
What is an increase in thermal energy?
How energy from the sun reaches Earth.
What is radiation?
What engineers must consider when designing a device, such as cost or size limits.
What are constraints?
Energy produced when particles vibrate and create waves we can hear.
What is sound energy?
The reason machines never use all their input energy for useful work.
What is energy being transformed into less useful forms like heat or sound?
Why temperatures alone does not tell you how much thermal energy an object has.
What is because thermal energy also depends on mass?
The process responsible for warm air rising and cool air sinking in a room.
What is convection?
What engineers use to decide if a design successfully solves a problem.
What are criteria
