What is the measurement of how fast an object moves relative to a reference point?

Vi. on another planet, a spring with constant 4.7 n/m is set up and allowed to expand verticaly freely. 8.4kg mass is placed on the spring and the spring extends 5.28m. calculate the exected extension on earth.

Whenever the net force on a moving object is zero its acceleration is
