CBSE Class 9 - Science -Work Energy and Power - Question Bank

Work Energy and Power

Question Bank

Here is the compilation of questions asked in CBSE Examination papers in last five years.

Q1: Is it possible that a body is displaced and yet its work is done is zero? If yes write an example?

Q2: If the net work done on a particle is zero, is it possible the particle has uniform speed? How?

Q3: A body is moving on a straight road against a frictional force of 5N. After travelling a distance of 1.5 km he forgot to take the correct path at a roundabout of radius 100m. He moves the circular path of 1½ cycles then he moves forward up to 2km. Calculate the work done by him.

Q4: A force of 7 N acts on an object. The displacement is, say 8 m, in the direction of the force. Let us take it that the force acts on the object through displacement. What is the work done in this case?
Q5: When do we say that work is done?

Q6: Write an expression for the work done when a force is acting on an object in the direction of its displacement.

Q7: Define 1J of work.

Q8: A pair of bullocks exerts a force of 140 N on a plough. The field being ploughed is 15 m long. How much work is done in ploughing the length of the field?
