Text Box: PHYS101 First Major Exam Formula Sheet

 

 

y = c xn  ;         dy/dx = cn xn-1

 

Motion in One Dimension

 

 

Motion with Constant Acceleration

 

 

 

Free Fall

 

a = - g      ;      g = 9.8 m/s2

 

Vectors

 

`a .`b  = a b cosq,   `a `b  = a b sinq

 

Motion in Two Dimensions

 

 

 

Projectile Motion

 

ax = 0                           (x-x0) = V0 t cosq0

ay = - g                         (y-y0) = V0 t sinq0 gt2

H = V02 sin2q0/2g          R = V02 sin2q0/g

                                                                                               

Uniform Circular Motion

 

                  

 

Relative Motion

 

`VPA  =   `VPB  + `VBA 

`VAB  = Velocity of A relative to B =  -`VBA 

 

Newton's Second Law

 


             S`F = m`a   Û     ;

 

Friction

 

fs,max  =  ms N    ;           fk = mk N
