Kinetic Energy
The following equation calculates the kinetic energy of an object:
E=5XMxy~2
where
E =
the kinetic energy of the object.
M =
the mass of the object.
V =
the velocity of the object.
Example. Part 1: Calculate the kinetic energy of a 5-gram object
moving with a speed of 450 meters per second.
