No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.
Yes. Velocity is speed and direction so it can change velocity by changing direction.
Instantaneous velocity is a vector quantity representing the velocity Vi at any point.It is the time rate of change in displacement.
instantaneous acceleration is the instantaneous change of velocity with respect to time.
Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.
The tangent at a point on the position-time graph represents the instantaneous velocity. 1. The tangent is the instantaneous slope. 2. Rather than "average" velocity, the slope gives you "instantaneous" velocity. The average of the instantaneous gives you average velocity.
It does not make sense to say that the instantaneous velocity is constant. Instantaneous velocity by definition means that it is the velocity at a moment of time. If this is a question on some homework, just say no. The acceleration, or rate of change of the velocity, is not necessarily constant.
Velocity is an instantaneous measure. Mathematically, it is the limiting value of the change in the position vector divided by the change in time as the latter tends to zero. Over larger time periods, the average velocity is the total change in the position vector divided by the total change in time. If velocity is constant, the average velocity will be the same as the instantaneous velocity.
The rate of change in position at a given point in time is instantaneous speed, instantaneous velocity.
The rate of change of position is the velocity. The velocity at a specific point in time is called the instantaneous velocity.
Yes. The velocity can change if the speed remains constant and the direction changes.
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
It's the change in velocity, the rate of change (derivative) which is instantaneous velocity. Acceleration can be positive or negative, meaning increased or decreased velocity respectively.
You think to velocity.Velocity is not equivalent to speed.
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
Dividing change of velocity by the time it takes to change the velocity. If acceleration is not constant, this will give you the average acceleration during the period; to get the instantaneous acceleration, you have to take the derivative of the velocity.
Instantaneous velocity mean change of displacement in extremely small amount time. (in math way, taking[ lim t--->0 (change in displacements/change in time) ]. instantaneous speed is the same expect displacement change to distance. So,because of very very small change in time, magnitude of distance and displacement will be same for any direction the object is moving.
Velocity is dependent on speed AND direction, therefore velocity will change if the direction is changed.
If v is the velocity, then it is dv/dt.If we start with v= dx/dt as the instantaneous change in position, then it is d2x/d t2
Instantaneous velocity is the rate of change of displacement at a particular time in the course of motion. Speed is the overall rate of change of distance for an entire journey calculated by dividing total distance travelled by total time spent during the motion.
This is normally referred to as "instantaneous velocity" although if there is no change in velocity with respect to time - that is, no acceleration or deceleration - you might simply refer to it as "velocity".
Average Velocity = (change in position) / (elapsed time) Instantaneous Velocity = [limit as elapsed time approaches 0] (change in position) / (elapsed time) See the Wikipedia entry for more information.
Yes. Acceleration is a change in velocity. With no acceleration, velocity remains constant, possibly at zero.
Divided by time.Average acceleration is (change in velocity) / (time interval) Instantaneous acceleration is calculated by making the time interval very small. This is written as dv/dt.
Reading the question carefully, I can state categorically, withoutthe slightest fear of contradiction, that YES, the object's velocityremains constant when its velocity does not change.
Velocity can change even if speed is constant.
