Question

Give 2 applications of newtons first law of motion and explain each of them in 4-5 lines.

Answer 1

• Newton’s first law of motion states that:- “An object tends to keep it's state of rest or motion until any external unbalanced force is exerted on it.”

*It is also known as the ‘Law of Inertia’ because it explains inertia. The credit of it's discovery goes to Galelio Gallilei and Newton.

Applications:-

• When we are inside a moving vehicle and when it suddenly changes it's direction, we tend to go in the initial direction we were following. This is due to inertia of direction.
• When a moving vehicle accelerates from rest, we fall backwards due to inertia of motion.
