What is the difference between constant, instantaneous, and average speed? constant speed is where the speed is the same throughout and instantaneous speed is speed given at any moment and average speed is a total distance traveled divided by the amount of time it took to travel it.

The average rate is the change in concentration over a selected period of time. It depends on when you take the measurements. The instantaneous rate is the rate at a particular time. It is determined by finding the slope of the tangent to the concentration vs time curve at that time.

The instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of x with respect to t: v(t)=ddtx(t). v ( t ) = d d t x ( t ) .

Displacement is a vector which points from the initial position of an object to its final position. ... Instantaneous velocity, on the other hand, describes the motion of a body at one particular moment in time. Acceleration is a vector which shows the direction and magnitude of changes in velocity.

Section 6.2 - Instantaneous Velocity and Acceleration. When an object s distance changes with time, its velocity is the rate at which the distance is changing with respect to time, while its acceleration is the rate at which the velocity is changing with respect to time.

Constant acceleration:change in the velocity by same amount each second. Uniform acceleration:a body is said to be in uniform acceleration,if it travels in a straight line and its velocity increases by equal amounts in equal interval of time.

A constant or uniform acceleration means that the speed of the object changes by the same amount every second. When the speed of an object is decreasing with time (ie slowing down), the object's speed is changing and so, by definition, the object is accelerating.

Instantaneous velocity is defined as the rate of change of position for a time interval which is very small (almost zero). Measured using SI unit m/s. Instantaneous Speed is the magnitude of the Instantaneous velocity. It has the same value as that of instantaneous velocity but does not have any direction.

Speed is the distance covered in unit time whereas velocity is the displacement covered in unit time. Speed is a scalar quantity and velocity is a vector. Speed only determines the magnitude that is how fast is a body moving whereas velocity determines the direction also that is in which direction the body is moving.

Average speed is a measurement of velocity over a period of time. Constant speed refers to your velocity at any point in time or period.

Speed is the rate at which an object's position changes, measured in meters per second. The equation for speed is simple: distance divided by time. You take the distance traveled (for example 3 meters), and divide it by the time (three seconds) to get the speed (one meter per second).

A body is said to be in uniform motion when it covers equal distances within equal time intervals. So that means at constant speed. However constant velocity also seems to be correct.

Terms in this set (22) Acceleration is increasing or decreasing speed or changing direction, whereas velocity is how much distance you cover in a given amount of time. What is the difference between constant velocity, instantaneous velocity and average velocity? Give an example of an object with constant acceleration.

Speed is the rate of change of distance(basically how much distance(m) has been covered in a particular time(s)). Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of velocity per unit of time.

Instantaneous Velocity. , and so on, the instantaneous velocity is not zero because the slope of the position graph would be positive or negative. If the position function had a minimum, the slope of the position graph would also be zero, giving an instantaneous velocity of zero there as well.

Acceleration is defined as the time derivative of the velocity; if the velocity is unchanging the acceleration is zero. Velocity is a vector, speed is a scalar magnitude of the vector. If the velocity vector changes direction you can have constant speed (not velocity) with a non-zero acceleration.
