The lecture Gravitational Potential Energy Example by Jared Rovny, PhD is from the course Energy of Point Object Systems.
Serena Williams holds a tennis ball above the ground at a height of 2 m to make a tennis serve. If the tennis ball has a mass of 0.3 kg, what is its gravitational potential energy U?
If a crane lifts a 2,000 kg car to a vertical height of 10 m from the ground, what is the increase in the cars gravitational potential energy? (Take g = 10 m/s²)
A ball is thrown up with a speed of v = 10 m/s from a height of h₁ = 2 m. At which height h₂ does the gravitational potential energy and kinetic energy of the ball become equal? (Take g = 10 m/s²)
