Speed Practical Report
Aim – To determine if different forms of movement for the same distance will affect the average speed. Hypothesis – Moving in different directions will affect the average speed because there are different actions involved in running, jumping and grapevines. Jumping involves a longer motion which will take the longest time because a jump covers the least amount of distance per second meaning a slower average speed. Running will have the fastest speed because this takes the least amount of steps. Grapevines will also have a fast average speed. Moving in different ways will affect the average speed.

Independent Variable- Movement style
Dependent Variable – Time to cover 10m
Controlled Variables- Distance, surface and the incline/decline
Method
Step 1 – Measure out a 10m distance with markers
Step 2 – Draw up a table with three activities of your choice Step 3 – Perform three different activities over 10m and record them Step 4 – Repeat step 3 by trialling each activity more than once. Step 5 – For each activity add all of the results together and divide by the amount of trials to calculate the average speed Results

Discussion
This practical had very little that could have been changed. To improve the practical more test could have been devised with different activities and people. This would have more movements to compare and tests to average out the result.

Conclusion
As the hypothesis states, moving in different ways will affect the average speed. This is apparent in the results which were collected over 10m. Running which was predicted to have the highest average which was the fastest at an average speed of 3.85m/s. Grapevines which was predicted to be the second fastest was with an average speed of 3.13m/s. Jumping which was...
