NCERT Class 9 Science Chapter 7 Work, Energy, and Simple Machines Test Mock Test
This free online test covers Chapter 7, Work, Energy, and Simple Machines, from the NCERT Class 9 Exploration textbook. The 30 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions
Q1.How does the chapter define the work done on an object by a constant force?
- AThe mass of the object multiplied by the displacement
- BThe force applied multiplied by the displacement in the direction of the force
- CThe force applied multiplied by the time for which it acts
- DThe force applied divided by the displacement produced
Q2.How is one joule defined in the chapter?
- AThe work done when a constant force of 1 newton displaces an object by 1 metre in the direction of the force
- BThe work done when a force of 1 newton gives an object an acceleration of 1 m/s squared
- CThe work done when a force of 1 newton acts on an object for 1 second
- DThe work done when a mass of 1 kilogram is moved through 1 metre
Q3.A force-displacement graph shows a constant force of 10 N acting over a displacement of 1 m. How is the work done read from the graph?
- AAs the area under the graph, giving 10 J
- BAs the area under the graph, giving 10 N per metre
- CAs the slope of the graph, giving 10 J
- DAs the height of the graph line, giving 10 N
