Objects change their state of motion due to the net force acting on them. Do you agree with this statement? Discuss with examples.
Yes to change the state of motion net change in motion that is the resultant net force is necessary as according to Newton’s First Law, Every body continues to be in motion until and unless an external force acts on it.
Example: 1. When we push a book, it moves.
2. Football moves when it is kicked.
