Energy Flashcard

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

You can increase the kinetic energy of an object by making it move faster.

Potential energy is the stored energy in an object due to its position or state. For example, a stretched rubber band has potential energy.

Shorter strings create a higher pitch sound.

Convection is the transfer of heat through the movement of fluids (liquids or gases). For example, warm air rising and cool air sinking.

Conduction is the transfer of heat through direct contact between materials. For example, a metal spoon getting hot when placed in a hot soup.

A spinning bicycle wheel is an example of kinetic energy.

A rubber band pulled tight without releasing it is an example of potential energy.

Increasing the mass of an object while keeping its speed constant increases its kinetic energy.

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.
