How can different distances and speeds result in the same velocity?

    Speed
In summary, the conversation discusses how two different distances and speeds can result in the same velocity of 8 m/s. The confusion arises from the approximation of numbers, as .8 m/s is the technically correct answer. However, the ratio of distance and time remains the same even if the actual numbers differ.

10m/13s = .769 m/s (made into 8m/s)

but 25m/32s = .78125 m/s (also made into 8 m/s)

how can they both be 8 m/s? when they have a different distance and speed?

made into 8 m/s ? It should be .8 m/s, they just approximated the number

and they don't have different distance and SPEED !marlon

so .8 is a correct answer for BOTH :S

why is this confusing ?

it's easy as hell...

velocity is the ratio of distance and time, so even if distance and time differ the ratio can be the same...
this is just like saying 2 = 10/5 or 2 = 6/3

1. How does distance affect speed?

Distance and speed are inversely proportional, meaning that as distance increases, speed decreases. This is because it takes longer to cover a larger distance at the same speed as a smaller distance. However, if the time taken to cover the distance is constant, then distance and speed are directly proportional.

2. What is the difference between average speed and instantaneous speed?

Average speed is the total distance traveled divided by the total time taken to cover that distance. It gives an overall picture of the speed during the entire journey. On the other hand, instantaneous speed is the speed at a specific moment in time, and it can vary throughout the journey.

3. How does speed affect the time it takes to cover a certain distance?

Speed and time are directly proportional. This means that as speed increases, the time it takes to cover a certain distance decreases. For example, if you are driving at a speed of 60 km/h, it will take you 1 hour to cover a distance of 60 km. However, if you increase your speed to 120 km/h, it will only take you 30 minutes to cover the same distance.

4. Can distance and speed affect an object's acceleration?

Yes, distance and speed can affect an object's acceleration. Acceleration is the rate of change of an object's velocity, which includes both speed and direction. If an object is traveling at a constant speed and changes direction, its acceleration will be affected by the change in distance and speed.

5. How can we calculate the speed of an object at a certain distance?

To calculate the speed of an object at a certain distance, we can use the formula: speed = distance ÷ time. This means that if we know the distance an object has traveled and the time it took to cover that distance, we can calculate its speed. For example, if a car traveled 100 km in 2 hours, its speed would be 50 km/h.
