Hollow cylinder Solid cylinder PHYSICS 111 CHEAT SHEET 2.Displacement, speed and velocity in 1d: avg speed= distance/time AVG acceleration= change in Velocity/change in time V=Vo+at x=1/2(V0+V)t X=V0t+1/2at^2 V^2=V0^2+2ax Vx=change in X/ change in time Ax= change in Vx/ change in time X=Xo+VoxT+1/2AxT^2 change in X=1/2(Vx+Vox)T Vx=Vox+AxT Vx^2=Vox^2+2Ax(change in X) same equations for Y, just remember that Ay= 9.8m/s^2= gravity ---------------------------------------------------------------------------------------------------------------------------- 3. Kinematics in 2D: Displacement=change in R=Rf-Ro avg. Velocity= Rf-Ro/Tf-To=d/t avg ACC=change in V/change in T Vf=square root of (Vx^2+Vy^2) angle= than^-1(Vy/Vx) projectile: Relative velocity: Vx relative to g= Vx relative to t + Vy relative to g ***4.Forces and Newtons laws of motion: F=MA Gravitational force=F+G(m1m2/r^2) G=6.673x10^-11 W(magnitude of weight/true weight)=MG Apparent weight=mg+ma Kinetic frictional force Fk=UkFn max static frictional force =Fsmax=UsFn REMEMBER IN
