what is kinetic energy formullar

Answer 1

Kinetic Energy is KE = 1/2 mV^2. where m is the mass of the object and V its velocity

Answer 2

Kinetic energy:

1/2 * m * v**2

m = mass

v = velocity

Notation: * means multiply, ** means exponent (v**2 means v squared)

Be sure to get the units right----e.g. kilograms and meters/second will give you Joules:
