Why does the sheet of paper fall slower than one that is crumpled into a ball?
A crumpled ball of paper has a smaller surface area compared to a flat sheet, leading to less air resistance and allowing it to fall faster. The crumpled ball also has more weight concentrated in a smaller area, increasing its momentum.
Why does a sheet of paper fall slower than one that is crumpled into a ball?
A crumpled paper ball has a smaller surface area compared to a flat sheet of paper, which increases air resistance and slows down its fall. The crumpled ball also has more internal air resistance, which further hinders its fall speed.
Why does a crumpled piece of paper fall faster than a flat piece of paper?
A crumpled piece of paper falls faster than a flat piece due to air resistance. The crumpled paper has a smaller surface area exposed to air compared to the flat paper, reducing the force of air resistance acting on it. This allows the crumpled paper to accelerate faster towards the ground.
What falls faster a crumpled ball of paper or a flat sheet of paper?
Assuming that both pieces of paper weigh the same, a crumpled piece falls faster in the presence of an atmosphere. In a vacuum, they would fall at the same speed due to the lack of wind resistence.
Why might a tightly crumpled ball of foil sink but a flat piece of foil of the same mass float in water?
The tightly crumpled ball of foil has a smaller volume with less air trapped inside, making it denser and likely to sink. The flat piece of foil has a larger surface area and traps more air, increasing its buoyancy and allowing it to float despite being the same mass as the crumpled ball.
Why does a crumpled piece of paper hit the ground before a flat piece of paper?
This is because the flat piece of paper has a greater surface area, thus creating more friction between the air and itself, (this is also known as air resistance). The crumpled ball however, has a smaller surface area, creating less air resistance. The shape is different, meaning that the amount of force it gets is also different.
How many plane surfaces are there in a ball?
None. There is one curved suface but no plane surface.
What is the surface area of a soft ball?
Surface area of a ball or a sphere = 4*pi*radius squared
When dropped from the same height why does a flat sheet of paper fall slowly than the same sheet when it is tightly crumpled into a ball?
Because when the sheet of paper is flat, it acts like a parachute, and collects much more air resistance. The balled-up piece of paper has much less surface area, so can collect much less air resistance, making it fall faster.
Why does a crumbled piece of paper hit the ground before a flat piece of paper?
The flat paper has more surface area, allowing it to catch more air and float. The crumpled paper on the other hand, does not, because it doesn't have as much surface area to spread the air out.
Can papper catch on fire in the microwave?
Yes, however it is difficult. It is unlikely that a single sheet of paper will catch fire, however, a stack of paper may. Also, a tightly, crumpled ball of a single sheet of paper can catch fire, whereas if it is loosely crumpled it is unlikely to catch fire. In the first case, a single sheet will not be able to capture enough microwave energy in order to heat, and also, it's very large surface area to weight ratio means that it will lose any heated gained very quickly to the cool outside. In the case of the crumpled ball, the three things that are necessary for fire to occur are a fuel, a source of ignition, and oxygen. When the ball is loosely crumpled the sheet may heat somewhat but it can't concentrate enough fuel in order to catch fire. However, if the ball is tightly crumpled the fuel can be concentrated and ignited.
'what is the formula of surface area of a ball?
Surface area = 4*pi*radius2
