Kinetic Energy Formula: [tex]\displaystyle KE = \frac{1}{2}mv^2[/tex]

  • Energy is in Joules
  • m is mass (in kg)
  • v is velocity (in m/s)

Explanation:

Step 1: Define

m = 20 kg

v = 10 m/s

Step 2: Find KE

  1. Substitute [KE]:                    [tex]\displaystyle KE = \frac{1}{2}(20)(10)^2[/tex]
  2. Exponents:                          [tex]\displaystyle KE = \frac{1}{2}(20)(100)[/tex]
  3. Multiply:                               [tex]\displaystyle KE = (10)(100)[/tex]
  4. Multiply:                               [tex]\displaystyle KE = 1000[/tex]
