Kinetic Energy

Question 1

The equation for kinetic energy

Answer 1

Kinetic = 1/2 mass x 2

velocity

Question 2

Examples

Find: KE M: 2kg V: 2m/s

Answer 2

KE=1/2m  2
               v           2
     = 0.5 x 2 x ( 2   )
     = 0.5 x 2 x 4
KE= 4J

Question 3

The units

Answer 3

Kinetic energy : J
Mass : kg
Velocity 2 : m/s
