Front

What is thermal energy?

Back

The total energy of all the particles in an object.

Front

Back

The energy an object has due to its motion.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects, while temperature is a measure of the average kinetic energy of particles.
