5W have been working hard to understand how air resistance and gravity impact on a parachute. They have planned their own investigation and carefully considered how to work scientifically and conduct a fair test.
Which force is greater in a parachute jump?
How did you ensure a fair test?
Why is it important to repeat the test several times?
Which force is greater in a parachute jump?
Gravity is the greater force in a parachute jump. I know this because even the air resistance is making the person go slower, the gravity is pulling the person down.
How did you ensure a fair test?
We ensured it was a fair test by:
Changing the material
Keeping the material’s length and width the same.
Keeping the string’s length the same.
By dropping it from the same hight.
Why is it important to repeat the test several times?
It is important because you need to make sure how much time it is going to take..
