What is the relationship between kinetic energy and speed of an object? Explain what it means.

  • This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.

hope it helps

KE = 1/2 • m • v2

where m = mass of object

v = speed of object

This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed.
