WARRIOR:
Weird question

The linear speed ( v in m/s) of a particle moving in a circular path depends on some or all of the following properties: r is the radius of the circle , w is an angular velocity in s^-1 with which the particle orbits about the circle , and m is the mass of the particle.There are no dimensionless constants in the equation.

What does 'There are no dimensionless constants in the equation.' mean?

(a) Find formula for v
 is it just r/w?

(b) Find a formula for F , the force on a particle moving in a circle , which also depends on some or all of the above properties and also has no dimensionless constants.


Thanks in advanced

ps: If anyone can tell me what topic is this? Homogeneity?

Dibss:
Are you sure this is IGCSE? :/

I know, right? :\

Kimo. This should help. However for only the (a) part. Do you know differentiation?

The answer is v = w.r
I have no idea how.

WARRIOR:
hmm thanks vin , thats a whole new topic i have to study.

And its AS PHYSICS (cambridge ) :/

I'm splitting the post to create a new thread in GCE AS & A2 Level (CIE & EDEXCEL) board > Subject Doubts > Science. Some smarty pants might take a notice on it. ::) Is it OK?
