How do people swim? Why is there no gravity in water? How do we float?
Swimming is a sport that involves moving through water using your body. It is a great way to exercise, relax, and have fun. But how do people swim? Why is there no gravity in water? And how do we float?
How do people swim?
We swim by using our arms and legs to propel ourselves through the water. Our arms move in a circular motion, and our legs kick back and forth. This creates a force that pushes us forward.
Why is there no gravity in water?
There is gravity in water, but it is less than it is in air. This is because water is denser than air. Density is a measure of how much mass an object has for its size. The more mass an object has, the denser it is. Water is about 800 times denser than air. This means that the force of gravity is 800 times less in water than it is in air.
How do we float?
We float because our bodies are less dense than water. This means that the force of gravity pulling us down is less than the force of the water pushing us up. The difference between these two forces is what keeps us afloat.
