Examples of inertia of motion
- INERTIA OF MOTION
Some examples of inertia of motion are as follows:
(a) A person trying to get down from a running bus falls forward.
Explanation: when the person gets down from a running bus the upper part of his body is still in motion and due to this inertia of motion the body topples forward even though he has set his foot on the ground.
(b) Passengers travelling by train fall forward when the train applies sudden brake
Explanation: due to inertia of motion the motion of all passengers is equal to the motion of the train and as soon as the brake is applied the passengers feet being in contact with the train floor stops while the upper part falls forward due to inertia of motion.
(c) Ripe fruits fall from the trees in the direction of wind.
Explanation: the tree sways along with the wind and the inertia of motion makes these fruits sway along with the tree branches. The fruits fall off due to the inertia of motion along the direction of wind.
(d) The swirling of milk in a glass continues even after the stirring is stopped.
Explanation: a person stirring a spoonful of sugar into a glass of milk finds the milk continuing the swirling movement even after the stirring is stopped and this happens due to the inertia of motion of the milk inside the glass.
(e) A toy thrown up by a boy inside a moving train moves along with the train
Explanation: the toy also attains the same velocity as the train inside the train and thus would move along with the train when thrown up. This will apply only when the train is moving with a constant speed or it might fall forward or backward if the speed is altered.
