Q: Which of the following is not an effect of unbalanced force applied to an object?
  • A. Change in the speed of an object
  • B. Change in the direction of motion of an object
  • C. Does not cause change in the speed of the object
  • D. Change in the steady state of an object
Correct Answer: Option C - Unbalanced force does not cause change in the speed of object it is not an effect of unbalanced force. The resultant force of all the forces exerted on an object is not zero, so such force is called unbalanced force. If an unbalanced force is applied on an object, there is a change in the speed, motion, steady state, etc. of the object.
C. Unbalanced force does not cause change in the speed of object it is not an effect of unbalanced force. The resultant force of all the forces exerted on an object is not zero, so such force is called unbalanced force. If an unbalanced force is applied on an object, there is a change in the speed, motion, steady state, etc. of the object.

Explanations:

Unbalanced force does not cause change in the speed of object it is not an effect of unbalanced force. The resultant force of all the forces exerted on an object is not zero, so such force is called unbalanced force.
