Kinetic Energy & Temperature

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of motion.

Front

What happens when you touch something cold?

Back

Heat from your hand moves into the cold substance.

Front

What occurs when two objects have different temperatures?

Back

Heat will flow from the warmer object to the cooler one until they both have an equal temperature.

Front

From where to where does heat transfer occur?

Back

Heat transfer occurs only from warm objects to colder objects.

Front

What is the relationship between Temperature and Kinetic Energy?

Back

Temperature decreases when Kinetic Energy decreases.

Front

What is Temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is the formula for Kinetic Energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What happens to Kinetic Energy if the speed of an object doubles?

Back

If the speed doubles, the Kinetic Energy increases by a factor of four.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state reached when two objects in contact have the same temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.
