Question

Read the following and answer any four questions from 19 (i) to 19 (v)

Balanced Forces when act on a body, the body either continues the state of rest or Uniform

motion. Unbalanced force may change the state of an object and produces acceleration. A

property called inertia is the inherent property of an object which resists any change in the

state of the body when force is applied. Mass of an object is measure of inertia.
