Introduction

Carla Jones 11y set 1                                 Physics Investigation.

Brief:  A parachute manufacturer wants to find a suitable design for a parachute, which will let fragile scientific interments land safely. You must research and design ways of solving this problem. Having completed the practical you must make recommendations base d on your results.

Factors that I could chose to investigate.

There were many things that I could have chosen to investigate all of which I thought would make a difference to the fall, speed or landing of a parachute. These were :-

 Surface area of the parachute,

 Material used to make the parachute,

 The Shape of the parachute,

 The number of strings on the parachute,

 The mass of the load attached to the parachute,

 The weather conditions,

 The height from which the parachute is dropped,

 The surface the parachute and load land on and,

 The length of the strings.

 Surface area of the parachute.

Basic information

Background knowledge.

Explanation of air resistance.

An object that is falling through the atmosphere is subjected to two external forces.

called the terminal velocity.

The following information was taken from a sky diving website and I have summarised the information give of the conditions they think best for skydiving. I think that it demonstrates how small changes could change the speed of the fall.

Drag Co-efficient The best way to describe this is the "thickness" of the air. Wave your hand about in the air quickly - not much resistance there. Now put your hand in a bathtub of water and try the same - it is harder work.  The water has a higher drag co-efficient than air. However, air does have a significant drag co-efficient too. Simply, the higher the drag, the slower speed things will fall at.

Surface area: This is the main part on which drag takes place. The larger the surface area, the more drag is created, and the slower things will fall.  E.g. Take a sheet of flat paper. Drop it, and watch it slowly fall. Now fold it in half twice and drop it again.

  1. Investigating the factors affecting the speed at which a parachute falls.

    My conclusion also supports my prediction. In my prediction I thought that increasing the mass would make the parachute fall faster, this is also what I concluded. Assuming that there is a constant gravitational pull, my conclusion would be correct under any circumstances.

  2. Investigating the effect of mass on a parachute

    > Weigh the plastercene so it is 5g and then 10g etc up to 25g. After using 5g measure 5g more and then add it on until you reach 25g. > Now, place the piece of plastercene inside the cone (with the tip of the cone facing downwards).

The measurements of area in the first worked well.

    Drop each parachute and time it with the stop watch until it falls to the ground, record the time and repeat 5 times.

  1. Squash Ball and Temperature Investigation

    It would also keep the temperature constant ensuring that the ball receives exactly the amount of heat required for its bounce test. If enough balls of the same type were available, it would have been better to use a different ball for each temperature that needed experimenting on so that

  2. Physics Design Practical

    One other force slowing the tub down is air resistance. Air resistance is when the face of the tub collides with the air particles and will slow the movement of the tub down. A force is a push or a pull and is measured in newtons.

  1. Investigating the amazingness of theBouncing Ball!

    These readings are as expected, as at higher temperatures energy is supplied to the ball, making it's molecules vibrate more violently making the ball bouncier. In order for a solid material to be deformed, work has to be done on it.

  2. Strength of a string practical investigation

    Method: The following is a method for the experiment: 1. All equipment will need to be collected, table, wooden blocks, manila string, pulley, masses and mass hangers, G-clamp, sellotape, marker and a metre rule. 2. Collect manila strings together and cut to 65cm long each using the meter rule and measure the diameter of each string using a micrometer.
