b/c fat floats. it makes it harder to float if there no fat. And it requires skill

Why do you float on water even though gravity is pulling you down?
This occurs due to the upthrust of water. Water exerts an upward force on the body. It is also called buoyancy.
How do people live though earth is round?
Because of gravity. Gravity is a force that pulls everything towards the center of the Earth. This force keeps people on the ground even though the Earth is round. Hope this helps!
What is the relationship mass and the force of gravity?
Mass is a measure of how much matter something has. Weight is the effect of gravity pulling on that mass. So an object that weighs 1kg on Earth would weigh less on the Moon which has less gravity even though the mass of the object is constant. The relationship is: Force of gravity on an object in a certain place = (object's mass) x (acceleration of gravity in that place) .
WHICH IS MORE POWERFUL GRAVITY OR MAGNETISM?
Well, let's see. If I have a paper clip on a table and a magnet in my hand, and I slowly pass the magnet over the paper clip, the magnet in my hand is pulling the paper clip up with magnetism. If my magnet is close enough to the paper clip, the paper clip will jump up to the magnet ... even though the whole Earth is pulling it down with gravity.
Why does Ian float on water even though gravity is pulling him down?
Sometimes science can be confusing. Buoyancy is the reason why Ian floats on water. This is the force that is exerted by a fluid that opposes the weight of an immersed object.Ê
What keeps the planets from being pulled to the sun's suface by gravity?
The energy of their rotation round their orbits acts against the central force of gravity, in the same way as a ball on a string can be whirled round even though the tension in the string is pulling the ball towards the centre all the time.
Does gravity stop you from jumping?
Gravity works equally on every particle in a "standard" object which is why all objects fall at the same rate. Yes, you can exert an upward force greater than 1G when jumping, but even during the jump, gravity is already working on decelerating your upward speed and pulling you back down.
Why do people feel warm after swimming even though the temperature of the sea is lower than that of the air?
because they have just exercised.
How does gravity affect skating?
Air resistance slows you down which is why ski racers wear tight suits to minimize air resistance.
Which is the slowest of the four swimming strokes?
The second fastest swimming stroke is Butterfly.
If gravity is always an attractive force between two objects why does a helium balloon fall up?
This is a really good question! Helium balloons 'fall' up because helium is lighter than air. In other words, even though gravity is pulling the balloon down, the helium is so light the balloon rises.
Do rocks have gravity?
Yes. everything with mass has gravity. Something the size of an everyday rock, though, does not have enough mass for its gravity to be noticeable.
