Question

write down the names of few devices that work upon principle of motion (may be any type). how there is a requirement of knowing about various types of motion ​

Answer 1

Answer:

Explanation:

Laws of motion :

Newton’s first law may more properly be ascribed to Galileo. It states that a body continues at rest or in uniform motion along a straight line unless it is acted upon by a force, and it enables one to recognize when a force is acting. A tennis ball struck by a racket experiences a sudden change in its motion attributable to a force exerted by the racket. The player feels the shock of the impact. According to Newton’s third law (action and reaction are equal and opposite), the force that the ball exerts on the racket is equal and opposite to that which the racket exerts on the ball. Moreover, a second balanced action and reaction acts between player and racket.

These four area unit rotary, periodical, linear and mutual. every one moves during a slightly completely different|completely different} approach and every form of achieved victimization different mechanical means facilitate North American country perceive linear motion and motion management.

periodical and linear
