A body is accelerating in a straight line. The unbalanced force acts:
In the direction of motion of the body.
In the direction perpendicular to the motion of the body.
In the direction opposite to the motion of the body.
None of these.
A body is accelerating in a straight line. Thus. an unbalanced force has to act on the body in the direction of motion of the body.
An unbalanced force acts in the direction of motion of a body. Then the body:
A non-zero force is acting on a body but work done is zero. Which of the following statements justify the above situation? 1. Distance moved is zero. 2. Force is perpendicular to the direction of motion. 3. Force is in the direction of motion. 4. Force is opposite to the direction of motion.
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?
