Question

Gadgets or devices based on principles newtons first law of motion in brief

Answer 1

Hey...
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 creft 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 frcition is space.
Hope this would help you.
Mark it as brainliest if you like.

1) train suddenly start moving forward the passengers standing in the compartment tends to fall backward:-. the reason is that the lowest part for the passengers body is in close contact with the chair as a train starts moving his lower parts share the motion at once but the upper part due to inertia of rest cannot share the motion simultaneously and so it tends to remain at the same place consequently the lower part of the body moves ahead and upper part is left Behind so the passengers tend to fall backward.

2) an athlete orphan drugs before taking a long jump:-. the reason is that by running a brings his entire body in the state of motion when the body is in the motion it become easier to take a long jump and he will be safe from getting any injury....
