High School Why does rocket velocity at touchdown use g=9.8 instead of g=-9.8?
So,while learning mechanics,I found that most questions use g=-9.8 ,but when calculating the velocity the instant a rocket touches the ground,the solution instead used g=9.8,which is very confusing.Other questions of similar workings used g=-9.8,anybody care to help?
