Can someone please explain the lift coefficient and drag coefficient in simple terms? Thanks.

How does the flap angle affect lift to drag ratio of a wing?

I am trying to measure the lift to drag ratio of a wing. I am measuring the lift by using a electronic scale. But how on Earth can I measure the drag force?

Hi all! Supposed I have my solution of sucrose, my light source, my polarizer. I shine my light source on my polarizer and plane polarized light passes through my solution, how then do I measure the how much my solution has rotated my polarized light by? And also, what kind of container...

I'm a little confused. How do I vary the optical activity of sucrose?

Hi! I want to conduct an experiment to investigate the effect of sucrose concentration on refractive index using a laser pointer however I would like to complicate this experiment as this is just a simple how x affects y experiment. It may also seem to straight forward as obviously higher...

Dear physics forum, If an object is launched from a water slide with an angle theta, would the angle of launch affect the speed of the object right before contact with the landing pool, with air resistance considered? Thanks.

Hello guys. I was wondering about slides in a water a park and how they calculate the landing distance to predict where a person who land in order to keep them safe by landing them in the water of course... and also at an appropriate speed. So I want to do an experiment on this by making a...

Hello guys! New here. Grade 11 student. I'm working on a project to investigate how roof angle relative to the horizontal vary with lift, according to Bernoulli's principal. The purpose is to reduce injury in storms. Problems are: Wind blows in all direction and I was thinking about...
