They say Superman is faster than a speeding bullet, but is his kinetic energy greater than the bullet's? Find a moving object's energy of motion with this calculation.
- Step 1: Multiply the two products together to determine the kinetic energy of the object. This will be the answer to the kinetic energy formula.
- Step 2: Label the resulting answer as a measurement of Joules, or J, such as 36 Joules. Now, compare objects' kinetic energies and debunk the old superhero catchphrases.
- FACT: Sound is a form of kinetic energy that moves in longitudinal waves through other materials at a velocity of 340 meters per second.
- Step 3: Multiply the mass by one half, or divide by two.
- TIP: For example, a velocity of 3 meters per second squared is 9 meters per second.
- TIP: Mass and weight are not the same thing. Mass measures the amount of matter an object contains, while weight is the measurement of the force of gravity on an object.
- Step 4: Find the velocity, or speed, of the object in meters per second. Divide the velocity by 60 if it is given in meters per minute or by 360 if it's given in terms of an hour.
- Step 5: Multiply the velocity by itself, or square it.
- Step 6: Determine the mass, in kilograms, of the object. Write the value down as m equals mass.
