Question

Give any five examples of newton's first law of motion

Answer 1

First law:In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.

Second law:In an inertial frame of reference, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma. (It is assumed here that the mass m is constant – see below.)

Third law:When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.



Here are some examples of first law :

One's body movement to the side when a car makes a sharp turn.

Tightening of seat belts in a car when it stops quickly.

A ball rolling down a hill will continue to roll unless friction or another force stops it.

If pulled quickly, a tablecloth can be removed from underneath of dishes. The dishes have the tendency to remain still as long as the friction from the movement of the tablecloth is not too great.

Shaking a bottle of ketchup. When bringing the bottom down, the suddenly stopping it, inertia is what causes the ketchup to come out of the bottle.

Answer 2

the 5 examples for newton's first law are:

when the bus which is at rest begins to move suddenly,the person standing in the bus falls backward.

when you are travelling in a bus the bus, sudden stop of the bus makes you fall backward.

consider a football placed at rest on the ground. it remains same unless some force is exerted.

make a stack of carrom coins on the carrom board. give a sharp hit at the bottom of the stack with striker. we find that bottom coin will be removed from the stack ans the others in the stack will slide down.

kick a foot ball you observe it flies in the direction we hit
