Solution
Newton’s first law of motion
Newton's first law of motion stated that an object will not change its motion until and unless a net force acts on it
Fidget spinner: The object will most likely not start spinning on itself before turning, but once turned, if no external force is provided, it will spin indefinitely.
The electric fan continues to move for a period after the electricity is turned off.
If you jump from a car or bus that is moving, your body is still moving in the direction of the vehicle. When your feet hit the ground, the grounds act on your feet and they stop moving. You will fall because the upper part of your body didn’t stop, and you will fall in the direction you were moving.
Newton’s second law of motion
Newton’s second law of motion is defined as the force on an object equal to its mass times its acceleration.
Airbags: In a forward motion, airbags mitigate the effects of force.
Seat belts: A seat belt restricts the motion of our upper body so that we do not knock our heads when the automobile stops.
Newton’s third law of motion
Whenever one object exerts a force on another object, the second object exerts an equal and opposite on the first.
Birds fly using the same technique. The birds force the air downwards, while the air forces them higher.
