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. |
