Question

9th project obtain information about commonly used gadgets or devices which are based on the prienciples of Newton laws of motion. Introduction etc

Answer 1

You can relate infinitely many things in daily life to cite Newton's laws of motion.

•You ride a vehicle. The road provides a frictional force against your motion. You stop after some distance. Newton's first law(every object in a state of rest will continue to be in rest and everything in the state of motion will continue to be in motion until and unless an external unbalanced force acts on it) . Frictional force is the external unbalanced force here.
•You broke two boards with hands. One with low force and another with more force. The second board breaks. Newton's second law (The magnitude of force is directly proportional to the acceleration produced.)
•You walk on your foot. You actually give force to the ground (action). And the ground gives another force (reaction). This is Newton's third law (every action has an equal and opposite reaction.)
