What is the manipulated variable in a controlled experiment in which a scientist is studying how long it takes a parachutes of different sizes to fall to ground?

The manipulated variable in this experiment would be the size of the parachutes. By changing the size of the parachutes, the scientist can observe how it affects the time it takes for the parachutes to fall to the ground.

The variable being studied is the size of the parachutes.


Why does smaller parachutes hit the ground before bigger parachutes?

If you have two parachutes, one big and one small, the biggest one will take more time then the other parachute. This happens because there is more room in the parachute which is causing air to go in side, which is air resistance. The smaller parachute has a lot of air resistance because it is smaller and there is less room for the air to go inside. However, the bigger balloon has little air resistance because it has more room in it for the air to get inside. The air is pushing the balloon up so it will fall slower.


Do bigger parachutes have more air resistance or drag force than smaller parachute?

Bigger parachutes have more air resistance and drag force than smaller parachutes. This is because the larger surface area of the bigger parachute creates more friction with the air, resulting in increased resistance and drag.


What is a proposed a scientific idea is called?

A proposed scientific idea is called a hypothesis. This is a tentative explanation for a phenomenon that can be tested through observations and experiments. If the hypothesis is supported by evidence, it may become a theory in the scientific community.
