Q1. What is it called when there is a condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity?
Q2. The displacement of an object moving under uniform acceleration is some function of time and the acceleration. Suppose we write this displacement as s=ka^mt^n, where k is the dimensional constant. Show by dimensional analysis that this expression is satisfied by m=1 and n=2. Can the analysis give the value of k?
