Potential and Kinetic Energy Concepts
Potential and kinetic energy are two fundamental forms of energy that play a crucial role in understanding the motion and behavior of objects.
Potential Energy
Potential energy is the energy an object possesses due to its position or state. It is calculated using the formula:
$PE = mgh$
Where:
- $PE$ is potential energy in joules (J)
- $m$ is mass in kilograms (kg)
- $g$ is acceleration due to gravity (9.8 m/s² on Earth)
- $h$ is height above a reference point in meters (m)
Kinetic Energy
Kinetic energy is the energy an object possesses due to its motion. It is calculated using the formula:
$KE = 1/2mv²$
Where:
- $KE$ is kinetic energy in joules (J)
- $m$ is mass in kilograms (kg)
- $v$ is velocity in meters per second (m/s)
Relationship Between Potential and Kinetic Energy, Potential and kinetic energy worksheets with answer key
Potential and kinetic energy are interconvertible. As an object falls, its potential energy decreases while its kinetic energy increases. Conversely, when an object is lifted, its potential energy increases while its kinetic energy decreases. This relationship is known as the conservation of energy.
