physics friction Flashcards
1
Q
What is the equation for Normal force?
A
Fn= mg
or
normal force=
mass x gravity
2
Q
what is the equation for static friction?
A
Fs = Ms x Fn
or
friction=
coefficient x normal force
3
Q
what is momentum’s equation?
A
p=mv
or
momentum=
mass x velocity
4
Q
what is the equation for the coefficient of friction/M?
A
M=Fr/Fn
or
coefficient of friction=
friction/normal force
5
Q
what is the kinetic equation?
A
Fk= Mk x Fn
6
Q
What is the sign of momentum?
A
kg*m/s
7
Q
What is the first step to finding the velocity after the collision?
A
We have to add the moments of the objects.
