Question

Conclusion of gadgets or device which are based on the principales of Newton law of motion

Answer 1

Newton's First Law states that " every object which is at rest or uniform motion continues to be in state of res or uniform motion unless compelled to change its state by action of net force.

Example:A space craft far from any source of gravity would need no thrust to keep it moving at a constant speed in a given direction.Once set in motion, it continues to move forever without propulsion since there is no friction.
