Why do fruits fall from tress when we shake them?

Question

Its not gravity..so please dont write gravity

We shake the trees, and the fruits fall..i want to know why does this happen..its not any biological reason..its not even gravity..its somewhat close to the first law of motion..but not exactly first law of motion

Answer 1

Specifically, there are a few forces at work here.
Shaking the tree causes acceleration.
The inertia of the fruit at the end of the stem causes stress on the stem.
If the force of acceleration is enough to break the tinsel strength of the stem, or if you shake the tree enough to reduce the tinsel strength of the stem, then the stem breaks, and gravity is free to accelerate the fruit down towards the earth.

Answer 2

The tree is designed to produce fruit as food for other species, and also as a way of propagating its own species. As it grows larger and riper and ready as a food, it drops to the ground to be eaten by animals and to have its seed carried by the animals to grow somewhere else. By shaking the tree, you're adding more strain to the stem and hastening the process, and getting the fruit to fall when you're there to pick it up. Unfortunately, if you shake hard enough, some of the fruit will fall before it is ready. Shaking moves the branches. Inertia tends to keep the fruit in place. For example, a light string may be strong enough to hold up a brick, but if you yank on the string, it will break.

Answer 3

Newtons First Law Of Motion that states bevery body continues in its state of rest or uniform motion unless it is exerted by an external unbalanced force
So as the trees are exerted by external unbalanced force the fruits fall from the trees on shaking it

Answer 4

Every object has a potential energy stored in them, or a vibratory rate at which it is existing on its own or atached to another object. so if u shake a tree for fruits to fall, u are only increasing this vibratory rate of the entire tree using an external energy or force. If the shaking is too vigorious, many fruits and even leaves are going to fall bcos they (fruiets & leaves) have exceeded the vibratory rate at which they are atached or existing on that tree.

Answer 5

As the fruit ripens the stems of the fruit dry and get weak. So they fall. Also sometimes if the tree is infested with bugs they will eat away at the stems to get to fruit, making the stem weak.

Answer 6

gravity- the stems aren't too strong, and they break and fall. But they fall because of gravity.

Answer 7

because they are ripe and ready to fall
