1. Problem: A book weighs 500 grams. Calculate the force exerted by the book due to gravity if the acceleration due to gravity is 9.8 m/s². Solution: Weight (Force) = Mass × Acceleration due to gravity Weight = 0.5 kg × 9.8 m/s² = 4.9 N So, the force exerted by the book is 4.9 Newtons. 2. Problem: A box has a mass of 10 kg.

Answer: The force resulting due to the action of muscles is called muscular force. Muscular force is called contact force because it comes in action on when two bodies come in contact of each other. The force which always acts on all the moving objects and whose direction is always opposite to the direction of motion is called force of friction.
