Front

Define work in physics.

Back

Work is defined as the product of force and displacement in the direction of the force.

Front

What is the formula for calculating heat transfer?

Back

Q = mcΔT, where Q is heat transfer, m is mass, c is specific heat capacity, and ΔT is the change in temperature.

Front

What is the difference between heat and temperature?

Back

Heat is the total energy of molecular motion in a substance, while temperature is a measure of the average energy of molecular motion.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, and X-rays.

Front

What is the principle of conservation of energy?

Back
