Calculate kinetic and potential energy
Energy Type
KE = ½ × m × v²
Energy in Physics
Energy is the capacity to do work. There are many types of energy: kinetic energy (energy due to motion), potential energy (stored energy), thermal energy, etc. The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
Types of Energy
Kinetic Energy (KE)
Kinetic energy is the energy an object possesses due to its motion. It depends on the object's mass and velocity.
KE = ½ × m × v²
Where: m = Mass (kg), v = Velocity (m/s)
Potential Energy (PE)
Gravitational potential energy is energy stored in an object due to its position in a gravitational field. It depends on the object's mass and height.
PE = m × g × h
Where: m = Mass (kg), g = 9.81 m/s², h = Height (m)
Practical Examples
Example: Moving ball
A 0.5 kg ball moving at 10 m/s has kinetic energy = ½ × 0.5 × 10² = 25 J.
Example: Elevated object
A 10 kg object at a height of 5 meters has potential energy = 10 × 9.81 × 5 = 490.5 J.
