. Explain inertia of motion and inertia of direction
Answers
The inertia of motion can be understood as follows: For a body that is already in a state of motion, it will have a tendency to continue in exactly the same state of motion (with the same speed and the same direction) unless an external unbalanced force acts upon it to change that state of motion.
The inability of a body to change by itself its direction of motion is called Inertia of direction. Example: Our protection through umbrella: The rain drops falling vertically downwards cannot change their direction of motion and so cannot wet us when the umbrella is up.
