why is it difficult for a car to round a curve at high speed?

Answer 1

Its because of the momentum. Momentum is based in mass and velocity. velocity considers direction. While at high momentum, any object cant easily change its direction.

If an object is moving in any reference frame, then it has momentum in that frame. It is important to note that momentum is frame dependent. That is, the same object may have a certain momentum in one frame of reference, but a different amount in another frame.

The amount of momentum that an object has depends on two physical quantities: the mass and the velocity of the moving object in the frame of reference

Answer 2

In a word momentum. Momentum is equal to force times mass. and since force is a vector (both magnitude and direction) so is momentum. So as you approach the curve your cars momentum is still trying to push you car in a straight line. In the absence of other forces you will continue in a straight line right off the road. When you steer around the curve the friction force between the tries and the road is the only opposing force, again a vector. When you add these vectors the magnitude and direction of the resulting vector changes.

Answer 3

A car rounds a curve due to centripital force acting on it by the direction of its wheels .
On the critical velocity the centripital force is equal to the centrifugal force which acts just opposite to the centripital force due to inertia of posiotion if the car
Thus at high speed i.e. speed > critical speed the centrifugal force becomes greater than the centripital force while the direction of wheels remains the same thus the car turs off due to its weight .
The same phenomenon can be seen in the case of a train .

Answer 4

Inertia of motion. Check out Newton's second law of motion.

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Moreover, the a higher trajectory is required at higher speeds, than in lower speeds.

Answer 5

Rotational force = m v^2 / r;
static friction ~ m * N * u (N = normal force usually g at a flat surface, cos theta * g + sin theta v^2/r for banked surface) (u = static friction coeffient)

if rotational force > static friction, the car is going to slip;
another thing to note is that static friction coeffient is usually much bigger than the dynamic friction coeffient, so when you start slipping you will slip a lot further than if you take a curve at a bigger radius)

(this is why some curves are banked, the angle helps keep the car from slipping)

Answer 6

at high speed centrifugal force pushes the car outwards while the friction has a certain limiting value..increasing the car's speed increases the centrifugal force but there's not enough friction to balance it and so the car goes out of control...

Answer 7

Inertia. the resistance to speeding up or slowing down. Oh and there's that whole resistance to GRAVITY thing going on also.

Answer 8

Its because of the momentum of the car. At high speed momentum of also high.

Answer 9

newton's first law says that something will continue to remain still or travel in a straight line unless acted upon by an unequal force. a large force is needed to turn it around the corner when it is going fast. it wants to continue travelling in a straight line.

Answer 10

you need to find the center point of gravity most of the time it is towards the top and because of the rate of speed and the angle you are turning and if the weight is in the correct spot thus you will roll over.
