If force acts at an angle to the direction of motion,it can
If the net force on an object is acting in the direction of its motion, its speed decreases.
If the force applied to an object is in the direction of its motion, its speed decreases.
A constant force acting on a body of mass 3 kg changes its speed from 2 m/s to 3.5 m/s in 10 second. If the direction of motion of the body remains unchanged, what is the magnitude and direction of the force?
