Question:  Which of the following is the application of Newton’s first law of motion?

  1. A) A rocket launching into space
  2. B) A car coming to a stop when the brakes are applied
  3. C) A ball rolling downhill
  4. D) A parachutist falling through the air

Answer: A car coming to a stop when the brakes are applied

Applications of Newton first law of motion        Description
Object at rest or in Motion An object at rest or in motion remains in its original state unless an external force is applied to change its state of motion.
Inertia in Space Travel In space, objects like spacecraft remain in motion unless thrusters are used to change their velocity.
Airbags Airbags in vehicles deploy to protect passengers by reducing the force of impact when a collision stops the car abruptly.
A Ball Rolling on the Ground A ball rolling on the ground tends to maintain its state of motion till infinity, if no external force acts on it.
Sliding on Ice Objects on icy or smooth surfaces keep moving unless acted upon by external forces, making it challenging to stop or change direction.
Spacewalks Astronauts in space can float and move at a constant velocity unless they use tools or thrusters to change their positions.
Space Satellites Space satellites remain in their orbits due to the balance of gravitational forces and their tangential velocity.
An object thrown in outer space If an object is thrown in outer space, it tends to move in a direction to infinity.
Washing Machine Dryer A washing machine dryer entirely works upon the principle of the law of inertia.
Dusting a Carpet Dust particles present in the carpet get carried away with air or fall to the ground due to gravity, thereby demonstrating the law of inertia.
