Investigating a Factor that Affects the Rate of Decent of a Parachute

Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle.

It is hypothesized that the different heights of the test subjects will affect their lung capacity. This is because taller people have larger lungs, therefore allowing their oxygen intake to be greater than those of shorter people.

When you are given the problem to find the mass of a mystery object, your first instinct is to find a weighing scale and see how much it weighs. Only in class we did it a different way. We had to find the weight of a mystery object by using a C-clamp and a device that has two metal plates and two metal rods. This was to measure the number of oscillations a certain mass does. When we were done with the lab I learned that there were other ways to find the mass of an object besides using a weighing scale. Our group got 4% off the actual amount so this method was

rate of fall of an object was determined by its weight held that matter was constructed out

n the course of your life you will go over numerous sorts of scale. Everything begins from your school lab, where research center scales are utilized to quantify the definite sum and extent of components, to direct a fruitful investigation. On the flip side, you have modern scales e.g. truck scales intended to weight the enormous weight of trucks or transports to ensure they can convey substantial hardware or traveler loads without tilting which can bring about serious mechanical or human misfortune.

In figure 1, the force of the gravity is pulling the person and the parachute towards the ground because gravitational force makes the object fall quickly. However, the parachute slows the person down because it causes air resistance as it pushes the parachute back up and creates an opposite gravitational force. The forces “push or a pull” are called action and reaction forces, the subject of newton’s third law. During this investigation, the push force is the air resistance and opposite (pull) force is the gravity.

Athletes used stone or lead weights called halteres to increase the distance of a jump. They held onto the weights until the end of their flight, and then threw them away them

Have you ever wondered how parachutes make you fall slower to the ground. People wonder because gravity pulls you down but how does a parachute slow you down. The whole point of this project is to find out what size parachute would work better for falling to the ground and the weight of the person the parachute is holding.

What was the attention getter? In the beginning, the speaker captured the audiences’ attention by simply asking them to make a realization of time. The speaker asked them to take a pause of 10 seconds; she also stated, “you are never more alive than when you are close to death.”

DESIGN Gravity makes objects fall down. In this experiment, with the help of gravity, water was poured down a conical beaker with different volume values and the time taken for all the water to empty the conical beaker was measured. In this experiment, the time measurements using Tracker software was stopped after the water reached the cylindrical part of the glass funnel. Research Question: How is the time taken for water to empty the conical glass funnel dependent on the volume of water? Independent Variable: Volume of water Dependent Variable: Time taken for water to empty the conical glass funnel except the cylindrical part of the glass funnel.

LC = How much an object weighs, HM = the horizontal distance of a person’s hands to what would be the midpoint of their ankles, VM = is the distance between your hands to the floor when your hands are vertical, DM = is the vertical distance between where the lift starts to the final placement of the lift, AM = Angle of asymmetry, FM = Average rate of lifts done per minute and CM = is a

In this lab, the researchers found which type of paper fell the fastest, when dropped from a height of 160 cm. The experiment was completed by using a flat sheet of paper, a paper folded up into fourth, and a crumpled piece of paper, and a ruler to see what happened when we drop them from 160 cm. The researchers predicted that if the way paper is folded is related to how fast it drops to the ground, then the crumpled piece of paper will fall the fastest. This confirmed the hypothesis after observing the experiment.

, ⍴: density of the fluid, V: upstream velocity, A: body area, FL: Lift force

Especially since not everyone takes into account the mass of each body , and only very few are able to add weight in kilograms variables.

However, the material is considered, too (M=4). Jessica’s initial explanations are frequently based on objects’ attributes, too (weight W=8, shape Sp=2, size Sz=3, material M=4). Nevertheless she has a more diversified range of explanations; she combines proprieties like mass and water mass (Ma-Wa=1), size and weight, which suggests incipient understanding of concepts like density (D=1).
