Question

in your everyday life you come across a range or motions in which
a) accelaration is in the direction of motion
b) accelaration is against the direction of motion
c) accelaration is uniform
d) accelaration is non uniform

Answer 1

In our everyday life the bodies carry out motion on the difficult trajectory under influence of many variable forces. Therefore bodies have non uniform acceleration of direction which does not coincide with the direction of motion.


Thus, the right answer is:
d) acceleration is non-uniform
