What is energy?

Back

Energy is the ability to do work or produce change. It can exist in various forms such as kinetic, potential, thermal, electrical, chemical, nuclear, and more.

Front

What is speed?

Back

Speed is the rate at which an object covers distance. It is a scalar quantity, meaning it only has magnitude and no direction.

Front

What is velocity?

Back

Velocity is the rate at which an object changes its position. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It is given by the formula KE = 1/2 mv^2, where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It can be gravitational, elastic, chemical, etc.

Front

What is force?

Back

Force is an interaction that, when unopposed, will change the motion of an object. It is a vector quantity and is measured in newtons (N).
