Why is the velocity accelerating with a constant linear tangential
Because the direction is constantly changing
What is the force equal too in a circular motion at the top and bottom of a circular motion
At top F=T+mg, at bottom F=T-mg
Conical pendulum
the vertical component tension is balanced with the weight and the horizontal component in the tension is unbalanced this causes a central force.
What is the conical pendulum radius
r=lsin(angel)
what happens when a vehicles exceeds a certain value of force of friction
The frictional force will no be large enough to maintain circular motion therefore the vehicle will skid off the road at a tangent to the curve.
vehicles on banked curves
vehicles on banked curves can travel faster speeds before skidding off a tangent, this is due to the centripetal force being greater on a banked curve.
