A 600 kg car is at rest, and then accelerates to 5 m/s. What is its original kinetic energy? J What is its final kinetic energy? J How much work was used? J

Two friends are having a conversation. Anna says a satellite in orbit is in freefall because the satellite keeps falling toward Earth. Tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/2.
