It is not. Average acceleration is (change of velocity)/(time for the change)

No, acceleration is rate of change of velocity!


No. Acceleration is (change of velocity) divided by (time interval in which it changed). If velocity doesn't change, then there is no acceleration.


-- The magnitude of acceleration is equal to the time rate of change of speed. -- The magnitude of acceleration is equal to the time rate of change of the magnitude of velocity. -- Acceleration and velocity are both vectors.


magnitude of acceleration=change of velocity/time invertal


If the object begins from rest and a constant force is applied to it, then at the end of one second, the magnitude of its velocity is numerically equal to the magnitude of its average acceleration, although the units are different.


what is magnitude of average velocity


With that information, you can find the average magnitudeof the accelerationduring that period of time. You can't tell what either the magnitude or directionwere at any time during, only the average magnitude for the whole interval.


No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.


Acceleration is the process of changing the magnitude or the direction of velocity, or both.


Yes, velocity and acceleration are vectors as they both have a magnitude and a direction.


acceleration = (final velocity - initial velocity)/time interval


The slope represents the rate of change of velocity, which is the magnitude of the acceleration. If the velocity vs time graph is a straight line, that means the magnitude of velocity is constant, and the magnitude of acceleration is zero. The graph conveys no information regarding the direction of velocity or acceleration.


magnitude of acceleration


magnitude of acceleration (change in magnitude of velocity over time)


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.


Yes. Since the direction of the movement changes, that means there is an acceleration. Remember, acceleration is a change in velocity; velocity includes both a magnitude and a direction.Yes.

The magnitude of the acceleration at every instant is the slope of the graph at that instant.The average acceleration over a period of time is the (difference in velocity during that time) divided by the (time).


Velocity is speed in some direction. Acceleration changes that speed or that direction (or both).


Speed is scalar (it doesn't have direction), and the magnitude of velocity (a vector). The first derivative of velocity is acceleration, therefore the first derivative of speed is the magnitude of acceleration.


Acceleration is the rate of change of the magnitude of velocity and the direction in which the velocity changes.


That's the magnitude of its acceleration.
