Energy Flashcard

Front

What is conduction in terms of thermal transfer?

Back

Conduction is the process of thermal transfer that requires direct contact between substances, allowing heat to flow from the hotter object to the cooler one.

What type of energy do falling rocks possess?

Back

Falling rocks possess gravitational energy, which is the potential energy held by an object because of its height above the ground.

Front

What types of energy are present in a cheeseburger?

Back

A cheeseburger contains potential chemical energy, which is the energy stored in the chemical bonds of the food.

Front

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, but it can be transformed from one form to another.

Front

What is electrical energy?

Back

Electrical energy is the form of energy associated with moving electrons, which can be harnessed to do work.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on an object's position or state, while kinetic energy is the energy of an object in motion.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, which is related to its temperature.

Front

What is the formula for gravitational potential energy?

Back

The formula for gravitational potential energy is PE = mgh, where PE is potential energy, m is mass, g is the acceleration due to gravity, and h is height.

Front

What are the three main types of heat transfer?

Back

The three main types of heat transfer are conduction, convection, and radiation.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.
