Introduction

To investigate the effect of surface area on a falling object.

JITESH PATEL 11C SCIENCE INVESTIGATION

AIM: The aim of this investigation is to find out the effect of surface area on a falling object.

PLAN:

1. Get and cut out of a paper helicopter and clip on a paper clip at the end of the helicopter.

2) Get a ruler and draw a marking of 2m on a wall.

3) Take a stop clock to time how long it takes the paper helicopter to fall at different surface areas.

4) Every time you do it cut

Middle

(Change)

• Length of the helicopter (surface area).

(Don’t change)

• The weight only (1 paper clip)
• The height
• The way you drop the paper helicopter
• Use the same helicopter
• Stop the clock as soon as it touches the ground

SAFETY MEASURES:

• Careful with the scissors
• Make sure that you dropping the helicopter from a safe place.

RANGE:

I will use the following length surface areas (7cm,6cm,5cm,4cm and 3cm)

PREDICTION:

I predict that as the surface area of a falling object decreases, the object will fall faster. This is because as the wingspan gets smaller there will be less air resistance pushing up on the object so it will fall faster. Gravity pulls the object to the earth and this will stay the same whatever the wingspan is.

TABLE OF RESULTS:

Conclusion

I was very happy the way that my graph came out and the way it looked. I tried my best and I achieved what I could with the graph and the investigation. I can improve my method my practising and learning through other investigations.

1. ## Catapult Investigation

3 star(s)

The more results taken give more reliable results. The elastic band was then pulled back at a force of 2 Newton's. The elastic band was then pulled back at a force of 3. The elastic band was then pulled back at a force of 4 Newton's.

2. ## Parachute Investigation

1 oz (28.4g) 1 1/2 oz (42.6g) 2 oz (56.8g) 2 1/2 oz (71.0g) The parachute was dropped every time from a height of about 7ft. Each of the 5 weights was dropped 3 times and the results added together to give the overall average falling time for the weight.

weights will be tied Each reading will be taken three times so as to make the results as accurate as possible. An average will then be taken to make the investigation more accurate and to take into account all three results for each point equally.

2. ## The Spinners Investigation.

You can' get an exact time taken for it to fall but the stop clock is the best instrument for the job as far as I can decide. The safety issues are important, like when you have to stand on the table to reach the ceiling you should make sure

1. ## How Surface Area Of Vanes Effect The Rate At Which A Weight Drops.

The amount of air resistance acting on an object depends on the object's surface area. If an object has a small surface area, it will have little air resistance. Because the piece of paper has a larger surface area than the marble, the marble will have less air resistance than the piece of paper and the paper will fall slower.

2. ## Investigating how height affects time taken for a falling object to reach ground level.

The height from which the ball is dropped is the independent variable, i.e. the variable that is changed and the dependent variable is the time taken for the ball to reach the ground. It is predicted that as the height from which the ball is dropped decreases, the time taken for the ball to reach the ground will also decrease.

1. ## Sliding beaker investigation.

I think this because of Newton's Second Law which states: "If there is an Unbalanced Force, then the object will accelerate in that direction". This basically means that when a force is exerted on an object it will move in the direction that the force is going.

If the forces acting on my helicopter give a net force which is zero, then my helicopter will not accelerate, it will continue moving at a constant velocity. The forces on an object falling at terminal velocity are balanced. Terminal velocity occurs when the weight of an object is balanced by the drag.
