Why do cars running very fast in a curve road tend to move out of the road in a path tangential to the curve road?

Velocity is a vector, meaning that along with the measurement of speed in meters/second, it also needs a direction. If a car was driving North at 10ms-1 that would be its velocity at that point. The car then turns left so it's travelling west at 10ms-1. The car's velocity has changed, therefore there must have been some acceleration for the car's velocity to have changed. That acceleration is always towards the middle of the circle that it is turning

∙ 10y agoBecause the classic racing technique is to do all your braking in a straight line before turning in to the corner, and then drive the car on acceleration into and through the turn. This basically uses the centripetal force of the drive wheels to drive to the apex and around the corner and counter the the effect of centrifugal force. The net effect is that race cars pick up speed as they go through corners.

∙ 11y agoThis is because of the car's momentum. Momentum is the tendency of an object in motion to remain in motion upon a straight line trajectory unless acted upon by an outside force. Even though the car may be moving at a constant speed, its velocity is changing because it is turning and therefore changing its vector.
This actually happens at any velocity, but it is most noticeable at higher speeds and in heavier vehicles because the magnitude of the momentum being overcome is greater.

∙ 9y agoAcceleration is the rate of change of velocity (how fast velocity changes - dv/dt). You should also remember that acceleration is a vector, meaning that direction matters. If any objects goes around - even at a constant speed - in a curve, its direction is changing, therefore its velocity its changing, therefore it is accelerating.

∙ 9y agoAs a driver enters a turn you will see him decrease his speed and go low into the turn, but as he comes around and out he will use the centrifugal force of the car to help accelerate out of the turn. By adding more speed as he comes out, combined with the weight and momentum of the car, the driver is better able to gain quick acceleration, while using less fuel to achieve it. You will see this force actually start to push them high out of the turn.

∙ 12y agoThe velocity is changing and is not constant. Velocity is speed as well as direction so there is a continuous change in velocity which means there is acceleration.

What is the unit of tangential speed and linear speed?
Tangential speed is how fast a point on a circular object is moving at a certain distance from the center whereas rotational speed is how many degrees (or radians) a point on the circle goes through in a period of time. Every point on a circle has the same rotational speed. The further out you go from the center, the higher the tangential speed is.
What features on modern cars help reduce air friction?
The most common features in modern cars that help to reduce air friction is the streamlined design of the bumpers and spoilers. The streamlined shape of fast cars also helps to reduce drag.
Why does an object move faster on a straight path than a curved path?
With a curved path you have to slow down to curve as with a straight path you dont have to slow down you can do as fast as you need to go to get threw it.
Is an engine bumping into a string of coupled railroad cars on a track producing transverse or compressional waves?
An engine bumping into a string of coupled railroad cars on a track produces both compression and transverse waives. The engine bumping into the cars creates compressional waves down the string of cars. These waves are taken up by the spring action of the Janney couplers. The law of inertia can cause transverse waves in the coupling motion that can force railroad cars off the track. Think of it this way. If all cars in a cut weight about the same, as one car bumps into the other most of the force is passed down the string of cars. If a empty car pushes into a loaded car too fast the empty car may not have the force to start the loaded car moving. All the force that the empty car has has to go somewhere. The only direction it can go is up or to the side derailing the empty car. That's why there are restrictions on how fast cars can be coupled together. The spring action in the couplers in railroad terms is called slack.
Does a steep learning curve mean learning fast or slowly?
Actually, it has little to do with the learner and more to do with how much there is to be learned. The steeper the learning curve, the more things one has to learn in a shorter amount of time; or the faster the increase in difficulty of the concepts to be mastered. - - - - - Additional: The metaphor "steep learning curve" originally came as a positive reference. A steep learning curve meant that one became quite proficient with a minimum amount of effort/time. It LATER came to be used in the opposite sense - as a negative reference to something difficult to learn (which actually is a shallow, not steep, curve!). A learning curve is shown as a graph of "amount of learning" in the Y axis and the "amount of time or effort" in the X direction. A relatively 'normal' learning curve would be a sloping 's' curve, with its tail starting at the lower left and progressing to the upper right where the head of the s lies. In common (technically incorrect) usage, "steep learning curve" is meant to indicate that to learn the subject/technique takes a long time and is difficult.

Why dont satellites in orbit fall to the ground like a ball in orbit?
They're given enough tangential velocity ('sideways' speed, parallel to the earth's surface) so that the curve of the earth falls away just as fast as the satellite falls.
a cross between a fast ball and a curve?
When a fast ball and curve ball are mixed together it is called a slider.
How was NASCAR racing started?
The bootleggers would get together on the weekends to race their moonshine running cars. These cars were highly modified, and very fast, to outrun the federal agents.
How do you measure the speed in NASCAR?
They measure engine speed in RPM, but car speed in MPH. If you want to know how they know how fast the cars go from the stands or the officials' booths, that is what radar guns are for. Inside the cars, the speedometer tells how fast they are going, and the tachometer tells how fast the engine is running.
When did Stars in Fast Cars end?
Stars in Fast Cars ended in 2006.
When was Stars in Fast Cars created?
Stars in Fast Cars was created in 2005.
What is sound for fast cars?
One of the reasons why cars go fast is what size of an engine they have.
What is the duration of Stars in Fast Cars?
The duration of Stars in Fast Cars is 1800.0 seconds.
What is fast ball?
A fast ball is when the pitchers throws the ball straight at the strike zone, it doesn't curve (curve ball) or lower (slider), it goes straight ahead.
Does a curve ball really curve?
Yes, the curve ball curves. This is because of the way the ball is thrown, which is a kind of a spin/jerky fast motion.
What are the cars in Need for Speed Undercover?
You would need a fast car in a dangerous mission while a bunch of people running behind you trying to kill you
How fast is sasquatch?
Some documented encounters have had Sasquatch running alongside and or chasing their cars at around 35 to 45 mph on regular and irregular terrain.
