physics
ok i saw the responses thanks still a little bit confused ok what variable is different or varaies in the sitations were you to walk say down a hill and feel that it is easier and when walking up a hill which is harder

physics
ok i'm doing a lab were walking different displacements I observed that the displacements were on different grades of steepness this would decrease the coefficent of kinetic friction?

physics
does the slope of a distance vs. time graph show the average velocity or the instaneous velocity I'm asked the question and don't know which one. I believe that it would be the instaneous value because the slope is refering to one point on the graph... not sure though

physics
hey wow thanks!!! I acutally understood just kind of werid because our book hasn't mentioned energy yet but I know about it from just regualr old physics I'm taking ap this year and doing the first chapters in order and it hasn't mentioned anything about energy yet...

ok a person is holding onto a piece of string at the end of the string is a ball the person whrils it around in a circle i've been asked what's the mininum value of at the top of the circle (this is swung around in a verticle circle) what is the mininum value the veloc...

How to prove this? Similar triangles. Notice the upper angle in that photo is a right angle (ramp to Fn), yes and i agree right anlge in which the angle of Fn to the vertical is an angle complement to Fp and the vertical. ok so your saying that... angle Fn Fw is complement to ...

ohh ok um Fw is the gravity and Fp is the x component and Fn is the y component??? how come the x component is drawn in a weired location but we got the triangle now thanks!!!

what's fw and Fp

ha ha i copied the lnik instead of clicking on it i got it thanks
