The average velocity has two parts to it: The average speed and the average direction. The average speed is: (the distance you travel between 0 and 3 seconds) divided by (3). The average direction is: the direction from (the place where you started at 0 seconds) to (the place where you finished at 3 seconds).
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
Average Velocity = change in position/change in time V = 35.2 m - 0 m/6.7 s - 0 s 4.8 m/s
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)
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
Average velocity is 0 when an object returns to its starting point after moving away from it. This means that the total displacement of the object is 0, resulting in an average velocity of 0.
The correct term is velocity, not velocity.There is no reason why an object cannot have 0 velocity and 0 average speed - relative to some fixed reference point. I assume that your school, for example, has 0 velocity and 0 average speed.
The average velocity has two parts to it: The average speed and the average direction. The average speed is: (the distance you travel between 0 and 3 seconds) divided by (3). The average direction is: the direction from (the place where you started at 0 seconds) to (the place where you finished at 3 seconds).
The average velocity becomes zero when an object returns to its initial position after moving in a straight line. This happens when the displacement is zero over a period of time.
Ok, lets start with the idea that: Average Rate per second = Average Velocity Average Velocity = Change in distance/Change in time = (d2-d1)/(t2-t1) Now lets define our variables and solve for the Average Velocity: d1 = 0 m d2 = 100 m t1 = 0 s t2 = 9.86 s Average Velocity = Change in distance/Change in time = (100 m - 0 m)/(9.86 s - 0 s) = 10.14 m/s<---This is the average velocity in m/s. The reason this is the Average Velocity or Average Rate per second is because in the calculations above we didn't account for positive and negative acceleration that may have occured during the measurement of this information.

The average acceleration of the cyclist can be calculated using the equation: average acceleration = (final velocity - initial velocity) / time. In this case, the cyclist's initial velocity is 0 m/s, the final velocity is 15 m/s, and the time is 10 seconds. Therefore, the average acceleration is (15 m/s - 0 m/s) / 10 s = 1.5 m/s^2.
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
Average Velocity = change in position/change in time V = 35.2 m - 0 m/6.7 s - 0 s 4.8 m/s
For the instantaneous value of average velocity, average speed and average velocity are equal.
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)
It depends on the sign of velocities. For example, if there are two velocities 7 and -7 m/s then the average velocity of the molecules will be 0. But, the square will be 49. The general thing here is that even if a velocity is negative, the square of EVERY velocity irrespective of the sign is positive i.e., squaring always removes the negative sign.
Velocity is speed and its direction. Average velocity is average speed and its direction.
