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.

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.

If you are talking about a position vs time graph, the slope gives the average velocity. Velocity is displacement/change in time. (Change in position is displacement). Position is on the y axis and time is on the x axis. The slope = (y2-y1)/(x2-x1) = change in position/change in time = average 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.

Velocity is the rate of change of position over time.

Velocity is the rate of change of position.

Velocity is the rate of change of position - i.e., the derivative of position with respect to time.Acceleration is the rate of change of velocity - i.e., the second derivative of position with respect to time.

change in position, also known as the integral of velocity or the second integral of acceleration

The rate of change of velocity. (As velocity is the rate of change of position.)

The rate of change of position is the velocity. The velocity at a specific point in time is called the instantaneous velocity.

Average velocity is change in position (displacement) divided by the interval.

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

No. Velocity is the change in position over time. So if the velocity is negative, then the change in position must be negative - unless time is moving backwards.

Rate of change in position is called velocity.

Average velocity = change in distance/change in time

Velocity = distance divided by time / Velocity = average speed over time / Acceleration = (change of) velocity divided by time elapsed Change in velocity = final velocity "minus" initial velocity divided by time elapsed

"Acceleration velocity" is a meaningless phrase. "Velocity" is the time rate of change of position. "Acceleration" is the time rate of change of velocity.

Velocity is used to find the rate of change in position.

Velocity changes when an objects position changes.

Acceleration is the rate and direction of change in velocity. Velocity is the rate and direction of change in position.

average velocity means change in displacement and time interval ratio is called as average velocity average velocity what is the velocity at particular instant of time

The rate of change of motion is known as acceleration. Acceleration is the change in velocity over change in time. Velocity is the rate of change of position, or change in position over change in time.

Rate of change of position = velocityRate of change of velocity = accelerationRate of change of acceleration = jerk, jolt, surge, or lurch
