Question

12 examples of law of inertia

Answer 1

1)When pulling a Band-Aid off, it is better to pull it fast. Your skin will remain at rest due to inertia and the force pulls the Band-Aid off.

2)A car that is moving will continue even if you switch the engine off.

3)If a ball is on a slanted surface and you let go, gravity will make it roll down the slope. It has inertia and if there is a level area at the bottom of the slope, it will continue moving.

4)When entering a building through a rotating door, inertia will allow the door to hit you in the back if you don't get out of the way.

5)If you are rolling a cart with something on top and you hit something that makes the cart stop, what is on top may fall off.

6)It is harder to stop a big vehicle, like a bus, than a smaller vehicle, like a motorcycle. There is more inertia with the bigger object.

7)A concussion occurs because your brain is still moving while the outside skull is stopped. This is what causes the injury.

8)Space probes are launched to get past the Earth's atmosphere. Then they coast due to inertia.

9)If you are on a train and the train is moving at a constant speed, a toy tossed into the air will go straight up and then come down. This is because the toy has inertia like the train and you.

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

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

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

Answer 2

According to Newton's first law of motion, a body continues to be in the state of rest or of continuous motion until and unless an external force acts on it. This property is called inertia.

Explanation:

The examples of inertia are given below.

1. Falling of a person backwards when a bus starts suddenly and falling of a person forward when the bus stops suddenly
2. Falling of leaves of a tree on shaking the branches.
3. Removal of dust particles from the carpet by beating it.
4. The moving of the blades of a fan even after switching off.
5. Coin tossed in the moving train goes up straight and comes down.
6. Falling of the luggage from the roof of the vehicle when the vehicle stops suddenly
7. Falling of a person in the direction of the vehicle if he jumps out of the vehicle.
8. The coffee or tea continues to swirl after stirring.
9. The motion of satellites around the earth.
10. The experience of jerk on the starting of a lift.
11. Running of an athlete before a jump.
12. Tightening of seat belts when the car stops suddenly.
