Formulae Handbook for Class 9 Maths and Science. Solution 3 Work is a scalar quantity. Work, as a physical quantity, requires only magnitude to be represented. Hence, it is scalar quantity. Solution 4 When a force of 1 newton moves a body through a distance of 1 metre in its own direction, then the work done is known as 1 joule. Solution 5 The condition for a force to do work on a body is that it should produce motion in the body. Solution 6 Energy is a scalar quantity.
