# Investigating a ski-jump essay

It also proves that air resistance is a big limiting factor. We can substitude the numbers again. Therefore I believe increasing the h2 will increase the time the metal ball travels in the air and therefore increase the distance.

This is because this can increase the time for the metal ball to accelerate and to leave the track with a higher velocity to produce a more significant mark on the sand tray. I believe this is Investigating a ski-jump essay reason that the line on the graph bends slightly. There can be three different ranges of the line of best fit but I have only drawn the most obvious one.

Evaluation The trend of the graph 2 is a very clear with a positve correlation. By calculating the differences, we can see that the differences get smaller because air resistance acts on the metal ball longer, as a result reduced the total horizontal distance travelled.

Investigating a ski-jump essay are different things that I could change to improve the accuracy of the experiment.

This sport event involves a steep ramp and a landing zone. I am going to use regular sizes boxes to increase the h2. The results prove that the equation is correct and that the range of a ball does depend mostly on the height it is dropped from and the height the ball leaves the ramp.

The forces of the projectile motion can be treated separately. I will change it by putting books and magazine underneath the sand tray. Another important factor is the piece of A4 and carbon paper I used to measure the horizontal distance.

Percentage error I will take the maximum result of the range and calculate the percentage error based on the uncertainty values. This turning point shows the effect of air resistance and the horizontal distance also starts to decrease at a bigger interval at that point.

The following diagram shows the force acting on the metal ball. Figure 1 shows how the projectile motion can be separate into 2 components. For the plastic ramp, it bends slightly after it is being clamped and before each recording, I would stick blue tac under the ramp and make sure that the end is horizontal and the horizontal distance is the same for every result.

It can provide more evidence for me to investigate the actual horizontal distance traveled. If possible, I can also use portable stands where it can moves up or down at certain level so that I can eliminate the uncertainty produced by the boxes. The distance will varies and this is the reason for me to take the average.

If the ball is being released from a higher or lower position, it will have an affect in the initial velocity leaving the ramp. It is very important to place the end of the ramp horizontally because we have to ensure that the initial velocity vector has no vertical component: I also assume that air resistance is neglected, so there are no forces opposing the action of the projectile and therefore leads to same distance in each interval.

Because of the nature of the soft surface on the boxes, the metal ball is not able to make an obvious mark on the A4 paper. By using carbon paper, I will put a cardboard under the A4 paper and place the carbon paper on top.

The equation is correct, but the only part that could affect the results in this way was the assumption that all energy was transferred. The error is not very big, however it can still be eliminated.

It is not stable and will relocate after the metal ball hits and bounces off. Since I am using h2 as the variable, I will measure it from the point of the metal ball leaving the ramp.

However, due to the error bars being so small, it will be very difficult to show these 3 lines together. It is the air resistance that oppose on the action of the projectile. However, if the object is sliding down, then the area contacting the ramp will be constant and therefore friction will be the same.

Therefore, for bigger h2 being in the air longer time is longer from calculations in predictionthe air resistance will oppose the action longer and therefore will reduce horizontal distance travelled.

Since the horizontal and vertical components are independent, we can treat vertical component by different calculations. It can change h2 effectively and reduce the percentage error to the very limit.Disaster has struck the Mr.

Investigating a Ski-jump Essay Sample Aim:To investigate how the starting position of a ski jumper affects the horizontal distance travelled in the jump. I will not take air resistance, friction and other various type of energy lost into account, however in practical I have to keep in mind that they do exist and cause variation in my results.
