Law of Conservation of Energy Introduction

Front

What is the Law of Conservation of Energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, commonly associated with gravitational potential energy.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases proportionally with mass; as mass increases, kinetic energy increases if velocity remains constant.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is positioned, the greater its gravitational potential energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy is converted into kinetic energy.

Front

What is the formula for gravitational potential energy?

Back

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

Front

What type of energy conversion occurs when a pole vaulter jumps?

Back

The conversion of potential energy to kinetic energy occurs as the pole vaulter rises and then falls.

Front

What is the effect of speed on kinetic energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by a factor of four.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in a system, representing the total energy of motion and position.
