A Physics Investigation
Aim
In this coursework I will be investigating into how a diameter of a
cone can affect the time it takes to hit the floor from the height of
2 metres. My partner or myself will drop the cone with the base facing
the ceiling. I will be trying to find out which cone travels through
the air the fastest by doing extensive testing on the different cone
sizes.
As I established above, I will be adjusting the diameter of the cone
and seeing if this has an affect on the time it takes to fall to the
ground. To obtain accurate results I will conduct the test three times
on each diameter this will enable me to take an average and disregard
the anomalous results.
But first I will need to investigate and get some background
information before I begin this will help me during the experiment and
it will also help me make an educated hypothesis as to what the
outcome of the experiment will be.
Background Research
===================
Aerodynamic
-----------
If an object is aerodynamic it has a shape which allows to pass
through air with less air resistance and drag than other objects. Cars
and planes are often given aerodynamic shapes to increase their
performance and speed. A windmills operation is an example of an
aerodynamic action.
Streamlined
-----------
If an object is streamlined it is designed constructed or shaped to
offer the least resistance to fluid flow. Streamlined is shaped
optimally for motion or conductivity.
Drag
----
Drag is the retarding force exerted on a moving object it slows the
object down and causes it to decelerate.
Parachute
---------
A parachute is an object that is designed to slow down the descent of
a falling body by creating a big surface area and increasing drag and
air resistance. The parachutes shape bares a resemblance to that of an
umbrellas and it also has the shape basic shape as the base of the
In this experiment we positioned a marble ball on a wooden roller coaster positioned on a physics stand in the sixth hole. Throughout the experiment, we used an electronic timer to record the time of the marble where it passed through the light beam of its clamp. We positioned the clamp at a certain point on the roller coaster and measured the distance from the marble to the clamp; the height of the clamp; and finally the time the ball traveled through the clamp. After we recorded these different figures we calculated the speed of the marble from the given distance traveled and the time. We repeated the step 14 times, then proceeded to graph the speed and the height. Next, we took the measurements of position of the clamp, height, and speed and calculated the potential energy, the kinetic energy, and the total energy. Total energy calculated as mentioned before. Potential energy is taking the mass (m) which is 28.1g times gravity (g) which is 9.8 m/s2 times the height. Kinetic energy is one-half times the mass (m) times velocity (v2). Finally we graphed the calculated kinetic, potential, and total energies of this experiment.
We tested an apple being dropped from a constant distance of 2.4m above the ground, this was used as a representation of a person falling from a high distance. We also tested a blood-like substance being dropped from a medicine dropper from a constant distance of 1.5m above the ground, this was used as a representation of a simple nose bleed.
The objective of the experiment was to discover the effect of mass and radius on the centripetal force of a system and determine the mass of a hanging object using the discovered properties. Centripetal force is the culmination of multiple forces that act on a spinning system. By attaching a known mass and changing the radius on between a center post and the unknown mass, the unknown mass can be calculated. Likewise, if the inverse is tested, with a variable known mass and fixed radius, the unknown mass can be calculated.
It is important that key factors in determining who is and who is not a risk to fall are sought out by the health care team. In this paper we will focus on how to determine who is a fall risk.
Finally, the experiment conducted in this report clearly shows that when a ball is dropped from a
Objective: After completing the experiment, we will be able to find the mass of objects using an inertial balance and compare them to accepted measures.
I believe that the purpose of doing this is to allow me to demonstrate my understanding of Elastic potential energy. And the projectile concepts of the effect of changing potential into kinetic energy and for me to demonstrate my ability to apply elastic potential energy to a scientific investigation.
The time of the filter paper to fall will be measured by a stopwatch. The filter paper will be dropped at an initial height of 2.54 m where time will start recording when the filter paper is dropped and stopped when it makes contact with the ground. The time will be recorded to the nearest .01s.
From the data table, we found that the more paper clips the faster it will fall taking average 2.10 seconds to reach the ground for the class when the whirligig had 4 paper clips on it. However, when the whirligig had only one paper clips it took an average of 2.4 seconds to fall to the ground for the class. This happened because the more something weighs, the greater relationship it has with gravity. The more weight something has the less air resistance can pull up on it and counter gravity but when less are used less gravity is pulling down on it making it float more. Which why fewer paper clips used on the whirligig the more time it takes to fall to the
This paper will explain a few of the key concepts behind the physics of skydiving. First we will explore why a skydiver accelerates after he leaps out of the plane before his jump, second we will try and explain the drag forces effecting the skydiver, and lastly we will attempt to explain how terminal velocity works.
In this inquiry the relationship between force and mass was studied. This inquiry presents a question: when mass is increased is the force required to move it at a constant velocity increased, and how large will the increase be? It is obvious that more massive objects takes more force to move but the increase will be either linear or exponential. To hypothesize this point drawing from empirical data is necessary. When pulling an object on the ground it is discovered that to drag a four-kilogram object is not four times harder than dragging a two-kilogram object. I hypothesize that increasing the mass will increase the force needed to move the mass at a constant rate, these increases will have a liner relationship.
Suppose a ball is released from a distance and rolls down an inclined plane, as shown in figure 1. At the bottom of the inclined plane, the ball strikes a level tabletop and bounces away. The inclined plane may be rotated to give a steeper angle, which will affect the time of travel across the tabletop.
The size of this depends on the mass of the object and the size of the

In this assessment of the projectile motion of an object, I found that it can be applied to many useful situations in our daily lives. There are many different equations and theorems to apply to an object in motion to either find the path of motion, the displacement, velocity, acceleration, and time of the object in the air.
