Velocity is a measure of speed, in distance over time. The route or distance travelled is independent because it bears no relevance. For instance, if one person drove 50 miles at 50 miles per hour the trip would take one hour. If another drove 100 miles at 50 miles per hour the trip would take two hours. In these two instances the routes are different, the times the trip takes are different but the velocity ( 50 mph ) is the same.

What are the difference of instantaneous velocity and average velocity?
Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.
What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
Why is acceleration measured in meters seconds squared?
Acceleration is the rate of change in velocity, that is the finishing velocity minus the starting velocity divided by the time taken for that change. Velocity is the rate of change in distance, that is the finishing distance minus the starting distance divided by the time taken for that change. Distance may be measured in metres and time in seconds. In that case velocity would be measured in metres per second. Acceleration is then measured in (metres per second) per second or metres per second2.
How does average speed relate the distance covered and the time taken for travel?
Average speed = Distance covered/Time taken
What is the distance traveled divided by the time taken to trave the distance?
D/t = rate (Speed, velocity, etc)
How is average velocity of a body calculated when its velocity changes at a non-uniform rate?
average velocity=displacement/total time taken
What is average velocity?
Average velocity is def.ined as the ratio of total displacement to total time taken.
Equation for calculating average velocity from displacement and time interval?
a=dv/dt average velocity = displacement divided by time take. so average velocity = displacement/time taken.
What is the change in velocity divded by the time taken to travel the distance?
Change of velocity / time = average acceleration.
What are the difference of instantaneous velocity and average velocity?
Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.
What is the formula used to calculate the velocity of an object?
The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.
What is the average acceleration between 0 seconds and 4 seconds?
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
What is average acceleration?
the ratio of the total change in velocity of the object during motion to the total time taken.
What is the average velocity in a truck?
It is the distance travelled in a given direction divided by the time taken to cover that distance.
Is velocity a vector or a scalar?
no its a vector quantity,not a scalar quantity,bcz still it z a velocity bt NT a speed On a typical journey the average velocity is the straight-line distance between the start and finish, divided by the time taken, and it also has a direction. The average speed is the actual distance run, divided by the speed. The average speed might not be equal to the magnitude of the average velocity. For example on a round trip the average speed might be 40 mph, while the average velocity is zero.
Why is average velocity multiplied by 2 to get final velocity?
Let's take a simple example to illustrate the concept. A pitch is thrown by a pitcher. It starts at zero velocity (in his hand) and reaches a final velocity of 100 mph. Average velocity will be (100 + 0)/2 = 50 mph Obviously the maximum velocity is 50 X 2 = 100 mph However this is only true if the initial velocity (or the final velocity for a ball slowing down) is zero.
What formula is used to calculate accleration?
Accelaration= change in velocity/time taken OR Acceleration=final velocity- initial velocity/time taken
