SUMMARY
The work done by gravity on a ball with a mass of 10 kg displaced 5 m under gravitational acceleration of 10 m/s² is calculated using the formula for work: W = mgh. Substituting the values, W = 10 kg * 10 m/s² * 5 m, resulting in 500 Joules of work done. The change in kinetic energy of the ball is equal to the work done, which is also 500 Joules, confirming the work-energy principle.
