Final answer:
Mangoes falling when a tree is shaken can be explained by Newton's first law of motion or the law of inertia, and involves the forces of gravity and the resistance from the mango's stem.
Step-by-step explanation:
The scientific reason behind mangoes falling when a mango tree is shaken involves physics principles, specifically Newton's first law of motion, also known as the law of inertia. This law states that an object in a state of motion or rest tends to stay in that state unless an external force is applied to it.
Mangoes rest on the tree due to the force of gravity pulling them downwards, while the stem provides an upward force balancing this gravity, thus keeping the mangoes in place. When the tree is shaken, this equilibrium is disrupted. The stem can no longer provide enough upward force to compete with the force of gravity, and as a result, the mangoes fall.
