Name the forces acting on a plastic bucket containing water held above ground level in you hand. Discuss why the forces acting on the bucket do not bring a change in its state of motion.

Soni says that the acceleration in an object could be zero even when several forces are acting on it. Do you agree with her? Why?

A constant force acting on a body of mass 3.0 kg changes its speed from 2.0 m s^(-1) to 3.5 m s^(-1) in 25 s. The direction of the motion of the body remains unchanged. What is the magnitude and direction of the force ?

The following is the distance time table of an object in motion (a) What conclusion can you draw about the acceleration ? Is it constant increasing , decreasing or zero ? (b) What do you infer about the forces acting on the object ?
