Question

a car goes round the corner; (a)which provide the centripetal force ? .(B) is more force or less force needed if the car is 1 . heavier 2. faster 3. going round a tighter curve?. (c)what would happen to the car if there were no centripetal force?

Answer 1

Explanation:

In Motion in Two and Three Dimensions, we examined the basic concepts of circular motion. An object undergoing circular motion, like one of the race cars shown at the beginning of this chapter, must be accelerating because it is changing the direction of its velocity. We proved that this centrally directed acceleration, called centripetal acceleration, is given by the formula

a

c

=

v

2

r

where v is the velocity of the object, directed along a tangent line to the curve at any instant. If we know the angular velocity

ω

, then we can use
