1109 - How can water and air transmit forces to move objects?

Imagine you're at the beach or playing with a pool, and you notice how the water can move objects like beach balls or pool toys. Similarly, when you're outside on a windy day, the air can also move objects like leaves or flags.

This is because both water and air are able to transmit forces. Forces are like pushes or pulls that can make objects move.

When you move an object through the water, like your hand or a stick, it creates a flow of water around the object. This flow of water can then push on other objects, like a beach ball, and make it move.

The same thing happens with air. When something moves through the air, like a plane or a bird, it creates a flow of air that can push on other objects, like a paper plane or a kite.

In both cases, the water or air is acting like a kind of invisible "hand" that can push or pull on objects and make them move. This is why water and air can transmit forces and make objects move, even if we can't see the forces themselves.
