If a dog with a mass of 8kg changes speed from 10m/s to 5m/s, how does its kinetic energy change?
The formula for kinetic energy is:
Where:
KE is the kinetic energy,
m is the mass of the object, and
v is the velocity of the object.
Initial kinetic energy when speed is 10 m/s:
Final kinetic energy when speed is 5 m/s:
