Understanding Thermal Energy

What is thermal energy primarily associated with?

• Light and sound

• Heat and temperature

• Magnetism and electricity

• Pressure and volume

What is the unit of measurement for thermal energy?

• Watt

• Newton

• Joule

• Pascal

How is kinetic energy transformed into thermal energy?

• Through magnetic fields

• By friction

• Using light energy

• Via sound waves

In an inelastic collision, what happens to the kinetic energy?

• It is completely conserved

• It is lost to gravitational energy

• It is transformed into thermal energy

• It is converted into potential energy

What is a characteristic of a perfectly elastic collision?

• All energy is converted to light

• No kinetic energy is lost to heat

• Some energy is lost to sound

• Total momentum is not conserved
