How Does Mass Affect Velocity on an Incline?

[man0005]

Homework Statement

Hey guys

I recently performed an experiment where we attempted to investigate the effect of the:
1) Mass of the object moving down the incline and
2) Vertical height of the incline
on the velocity of the object at the bottom of the incline (using conservation of energy laws)

I'm having a bit of problems with the discussion so far
So far I've talked about how the results show that the mass of the object doesn't affect the velocity and how only the height will have an effect. I used my graphs to show this as well as showing that height is proportional to v^2
but I've only got about 150words from that...
so if anyone had any ideas on other things i could talk about, that would be really good

Homework Equations

The Attempt at a Solution

 

[supratim1]

mgh = 1/2 mv^2, m cancels, so mass has no effect.

I've said that already..
any other ideas?

 

[supratim1]

surface should be frictionless.

150 works on just "velocity of block sliding down the incline" ?
If you chose the topic ... REALLY BAD CHOICE

apart from topic .. yo can calculate coefficient of static friction by using incline and mass m

but i guess there's nothing more to write on topic except that in case friction acts .. velocity will decrease as mass will increase
