 # How Do We Find Speed?

## Is Nascar faster than f1?

When it comes to speed, NASCAR undeniably falls behind the other two popular races, IndyCar and Formula 1.

Despite being powered by a V-8 engine, NASCAR vehicles average out at a top speed of just over 321 kmh (200 mph), which is quite a bit slower than the top speeds recorded in F1 and IndyCar vehicles..

## Which car is fastest?

World’s Fastest CarsSSC Tuatara: 316 mph.Bugatti Chiron Super Sport 300+: 304 mph.Hennessey Venom F5: 301 mph*Koenigsegg Agera RS: 278 mph.Hennessey Venom GT: 270 mph.Bugatti Veyron Super Sport: 268 mph.

## What is unit of speed?

The speed of an object is how far the object travels in one unit of time. The formula for speed is: speed = distance time. The most common units of speed are metres per second (m/s), kilometres per hour (km/h) and miles per hour (mph).

## What is the fastest f1 speed?

372.6 km/hThe fastest outright speed recorded in a Grand Prix race is 372.6 km/h (231.5 mph) by Juan Pablo…

## Is Bugatti faster than f1 car?

The F1 Has a Great Acceleration, and is built for track and handling, and not for the speed dimension. … It is a fact that a Bugatti Veyron is faster than a F1 car in terms of top speed. But when it comes to overall performance the F1 can outrun the Bugatti inside a closed circuit or race track.

## Is 300 horsepower a lot?

300 horsepower is indeed a lot. Of course it all depends on how heavy of a vehicle you are driving. But for an average car, 300 is quite a good amount of power. … It has a 1.4 L turbocharged 4 cylinder engine that produces 164 hp moving a curb weight of 2360 lbs to a top speed of approximately 140 mph.

## How do you find minimum speed?

Explanation: The minimum or critical speed is given by vcritical=√rg . This is the point where the normal (or tension, frictional, etc.) force is 0 and the only thing keeping the object in (circular) motion is the force of gravity.

## What is better acceleration or speed?

Of course there is greater speed when you have faster acceleration because you are increasing speed, but the main issue is one of how quickly an athlete can accelerate and increase speed in a given direction, and not how fast an athlete is capable of sprinting if allowed more time.

## What is the formula to find the speed of a body?

How To Calculate Speed? A: For a body moving at a uniform velocity you can calculate the speed by dividing the distance traveled by the amount of time it took, for example one mile in 1/2 hour would give you 2 miles per hour. If the velocity is non-uniform all you can say is what the average speed is.

## What is the formula for maximum speed?

Comparing this equation to v = vmax cos (ωt + φ), results in the value of maximum speed in SHM, simply vmax = Aω.

## Does HP affect top speed?

For cars, horsepower translates into speed. So if you want to go faster, and get up to speed quicker, you need more horsepower. Torque, on the other hand, is the expression of a rotational or twisting force. In vehicles, the engines rotate around an axis, thus creating torque.

## What is difference between velocity and speed?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.

## Is 500 hp a lot?

But the perfect amount of horsepower, in any car, is right near 500. Let me explain. First, 500 is nice and round, halfway between zero (a terrible amount) and 1,000 (way too much). … The Ford Mustang GT350 is just over at 526 hp, and my ’14 Mustang GT, well, it starts at 420.

## Can the speed of body be negative?

The ratio of distance travelled and the time taken by a body can be zero but not negative. Since distance and time are positive quantities and speed is obtained by the ratio of these two quantities, speed cannot be negative.

## How is HP calculated?

The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.

## Is there a maximum falling speed?

The maximum speed is called terminal velocity. … The terminal velocity of a skydiver in a free-fall position, where they’re falling with their belly towards the Earth is about 195 km/h (122 mph). But they can increase their speed tremendously by orienting their head towards the Earth – diving towards the ground.
