About Kinetic Energy
Energy cannot be created or destroyed, but it can change forms. Kinetic energy is the energy of motion. Any object that is moving has kinetic energy.
The Equation
KE = ½mv²
Note that velocity is squared. This means a car traveling at 60 mph has 4 times the kinetic energy of a car traveling at 30 mph, not double. This is why high-speed collisions are so much more destructive.
FAQ
What is kinetic energy?
Kinetic energy is the energy that an object possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
What is the formula for kinetic energy?
The formula is KE = ½mv², where m is mass and v is velocity.
Why is velocity squared in the formula?
Velocity is squared because kinetic energy is related to momentum (mv) integrated with respect to velocity. Practically, it means doubling your speed quadruples your energy.
