The fact that a cannon always moves in a backward motion after shooting a cannonball is an example of:
|
|
Newton’s First Law of Motion
|
|
|
Newton’s Second Law of Motion
|
|
|
Newton’s Third Law of Motion
|
|
|
Newton’s Law of Cannonballs
|
Explanation:
Detailed explanation-1: -As per Newton’s third law, for every action there is an equal and opposite reaction. In this case, the action is the force exerted by the cannon on the cannonball, which causes the cannonball to move forward. The reaction is the force exerted by the cannonball on the cannon, which causes the cannon to move backwards.
Detailed explanation-2: -Bouncing a ball: when a ball hits the ground, the ball applies an action force on the ground. The ground applies a reaction force and the ball bounces back. Flight motion of a bird: the wings of the bird push air downwards as action force, and the air pushes the bird upwards as reaction force.
