Oh I understand your point now. Thanks for all your help but I just want to clarify one point you said: "or ascertain the force of friction due to the surface slanting the surface and using gravity as the constant known force (easiest)" I'm not too sure about what you wrote here. Are you...

I think you are misunderstanding what I meant when I said use a spring. I meant use a horizontal spring and compress it. I can measure the max. compression but I need the spring constant to determine the force. By doing this I can keep my force constant correct? Perhaps you can point me in the...

For experimental purposes I will need to include friction in the investigation. As for the whole algebra part for the spring constant I'm not sure I understand what you mean. I know Hooke's Law: F=-kx but how do I determine the spring constant with two known masses. (if it helps both masses are...

Homework Statement I need a method for my experimental lab procedure that allows me to use the same force multiple times. I need to provide a constant force to object A that causes it to collide with object B -- on a horizontal plane. I thought of using a spring on object A where F=kx but...

Number 1 was just the power rule. Number 2 I don't know either sorry.

For this, I thought about having hooks on either end of the wind tunnel and then tying it to the plane and then having the fan start up so the plane would receive a tailwind and I could measure the lift in the plane. However, I'm not sure as to where the scales come into play if I were to use...

Aerodynamics -- Wind tunnel I'm not sure if this goes under here since it's not actually homework but it's more of a general question for a paper I have to do, so if it's in the wrong place I apologize; simply tell me and I'll delete it or something. Okay well for my research paper I'm...
