Q

How to use fluid method with RUBBER BANDS

A

1) use glass cylinder
2) Place a VISCOUS fluid like bubble bath ( not messy)
3) clam a ruler next to cylinder set sqaure etc
4) wrap RUBBER BANDS of equal displacment
5) measure time taken to go through each one
6) as we know distance find thr VELOCOTY average between each one , and then plot velocity and time

Velocity where graph tends to is final velocity

Q

Why to increase spacing on rubber bands

A

Reduced uncertiwnh for both distance measured and the time between each, but not too much such that point where terminal velocity is found is removed

Q

When taking magent out using magent, what’s consideration about dropping on side, thus what should you do
