Work, Energy, Power and Gravitation GK Practice Quiz Level 2
This Level 2 General Awareness quiz on Aptitude360 covers the physics of work, energy, power and gravitation, from the universal law of gravitation and free fall to SI units and household electricity units. It mixes statement-based, match-the-list and simple numerical questions, and every question has a written solution.
Topics covered in this Level 2 physics GK set
- Universal law of gravitation and how the force changes when mass or distance changes
- Free fall, acceleration due to gravity and why heavy and light objects fall together
- Mass versus weight, and why an object weighs less on the Moon
- Work done by a force, including cases where no work is done
- Kinetic and potential energy and the law of conservation of energy
- Power, the watt, the kilowatt and the commercial unit of electricity shown on a bill
Key concepts to revise for work, energy and gravitation questions
- SI units and the scientists they are named after: newton, joule and watt
- The difference between the universal gravitational constant and the acceleration due to gravity
- The inverse square relationship between gravitational force and distance
- Gravity's role in tides and in keeping the Moon in orbit around the Earth
- Odd-one-out logic: power is a rate, while work and the forms of energy are amounts
Revision tips for gravitation and energy GK
- Make a quick table of quantity, formula and SI unit, since match-the-list questions test these pairs
- Practise how gravitational force changes when mass and distance change together
- Treat each numbered statement separately before choosing the combined answer option
- Convert an appliance's power and running time into units of electricity before comparing energy values
Who should take this physics GK quiz
This set suits General Awareness aspirants who have revised basic mechanics and want medium-level practice before moving to tougher physics sets.
