• Kinetic energy (Ek) is the energy an object has due to its?motion?(or velocity)
  • The faster an object is moving, the greater its kinetic energy

• When an object is falling, it is?gaining?kinetic energy since it is gaining speed
  • This energy transferred from the gravitational potential energy it is losing
  • An object will maintain this kinetic energy unless its speed changes

• Kinetic energy can be calculated using the following equation:

Kinetic energy (KE): The energy an object has when it is moving

Derivation of Kinetic Energy Equation

• A force can make an object accelerate; work is done by the force and energy is transferred to the object
• Using this concept of work done and an equation of motion, the extra work done due to an object's speed can be derived
• The derivation for this equation is shown below:
