BALANCE FORCES
Q1) What are balanced forces?
Q3) Give one example of unbalanced force
Q4) What is inertia?
Answer Key
Q1) What are balanced forces?
And When 2 forces acting on an object are equal in magnitude but opposite in direction search forces are called balanced forces.
Q3) Give one example of unbalanced force?
Ans Unbalanced force acting in a tug of war.
Q4) What is inertia?
Ans The property of objects by virtue of which they oppose any change in their state of rest or motion is called inertia
