Velocity of COM
Unchanged, assuming no resultant external forces are acting on the system. Add equation.
Total momentum during a collision
Is conserved (unchanged) assuming no resultant external forces are acting on the system. Add equation.
Increase in mass towards centre of rotaion
I=mr²
r decreases, m increases, I decreases
OR
L=Iw
w increases, L is constant, I decreases
Ek (ROT) changes
Equation
Heavier COM causes I to decrease, hence w increases
Ek (ROT) will decrease & Ek linear will increase
L
Angular momentum is conserved no external torques act.
Max speed in banked corners
v=root(rgtan˚)
If mas speed is exceeded the Fc is too small to cause circular motion
The object will move in a straight line at a tangent to the bend
