Instantaneous speed: The speed at which I'm moving right now, this instant.

Average speed: (The distance I covered during some period of time) divided by (the length of time).
I may have had different instantaneous speeds at different points during that time.

Acceleration: The rate at which speed changes. Acceleration can also be instantaneous or average over
a period of time.

What is the difference between average acceleration and instantaneous acceleration?

Average acceleration is the average of the accelerations acquired in the whole journey by a body while instantaneous acceleration is the acceleration of the body at any particular instant of time.


What is the difference between Average Speed and Instantaneous Speed?

Suppose you accelerate in your car from stopped to 50 km.hr-1. When you were stopped your instantaneous speed was zero. At the end of the period of acceleration your instantaneous speed was 50 km.hr-1. If your rate of acceleration was constant then your average speed was 25 km.hr-1.


What's the difference between instantaneous velocity and instantaneous acceleration?

Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time


What is the difference between instantaneous speed and speed?

Instantaneous speed is speed measured at a specific time. Speed is an average.


What is the difference between instantaneous speed and average speed?

Instantaneous speed is the speed at a particular moment in time.The average speed of an object tells you the (average) rate at which it covers distance


Whats the difference between average velocity and instantaneous velocity?

the instantaneous velocity or speed is the speed a body travels at a particular and average velocity is the total distance an object


What is the difference between tangential acceleration angular acceleration and centripetal acceleration?

Tangential acceleration is acceleration in the direction of travel, i.e. tangent to the instantaneous velocity. Centripetal acceleration is perpendicular or normal to that, specifically, in the direction of the acceleration, i.e. towards the center of the circle of travel. Angular acceleration is anything in between, or outside of those two definition, i.e. not tangent and not normal.


Difference between instantaneous and average velocity?

Average velocity is simply displacement over time. Instantaneous velocity is the velocity at any given instant, or the displacement over an infinitely small amount of time.



What is the difference between the average reaction rate and the instantaneous rate?

The instantaneous rate is the rate at a particular moment in the reaction (point of interest) and the average reaction rate is the appearance of a product over a particular time interval.


What is The basic difference between instantaneous and average speed?

Instantaneous speed:- It is the rate of change of position with respect to time,at that instant. Average speed:-Average speed is defined as the total path length travelled divided by the total time interval.


Difference between average velocity and instantaneous velocity?

average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)


Difference between average velocity and constant acceleration?

Avg velocity is the speed you are going. Constant acceleration is the rate you increase your speed. = =


What do speed and acceleration have in common?

Speed is how fast you are moving. Acceleration is the rate at which speed is changing. In strict physical terms, acceleration is the difference between the ending and starting speed divided by the time over which the change occurred. In that sense the word can mean that speed is increasing (positive acceleration), decreasing (negative acceleration), or not changing (zero acceleration). However in common usage, negative acceleration is usually called deceleration. Acceleration can be calculated as an average (Δv/Δt) or an instantaneous (dv/dt) measurement.


What is the slope of a staircase?

Average or instantaneous? The average is the height divided by the horizontal distance, whereas the instantaneous alternates between zero and infinity.


What is the difference between instantaneous velocity and instantaneous speed?

Speed, instantaneous or not, is a term used for how fast an object travels. Velocity, instantaneous or not, is a term used for how fast an object travels in a particular direction.


What is the difference between a slope and rate of change?

Depends. Slope of tangent = instantaneous rate of change. Slope of secant = average rate of change.


What is the difference between gravitational acceleration and acceleration?

Gravitational acceleration is simply acceleration due to gravity.


What is the relationship between average velocity and instantaneous velocity?

The average velocity over an time interval is the average of the instantaneous velocities for all instants over that period. Conversely, as the time interval is reduced, the average velocity comes closer and closer to the instantaneous velocity.


What are the difference between velocity and acceleration?

Acceleration is the rate of change of velocity.


What is the difference between acceleration and the acceleration of gravity?

Their almost the same, because acceleration is because of gravity.


What is the difference between radial acceleration and tangential acceleration?

The difference is in the direction of the acceleration. Tangential acceleration is in the direction of movement. Radial acceleration is at right angles to it (towards, or away from, the center of a circle for example).


Instantaneous speed at an instant is equal to magnitude of instantaneous velocity at that instant?

That's correct, the instantaneous magnitudes are equal. Non-instantaneous values may not be equal. For example, to find average speed, between two points, you divide the actual path distance by the time, but for average velocity you divide the straight line distance, between the points, by the time. The straight line distance could be quite a bit shorter then the actual path distance (for curved motion) so you could get a big difference between those averages. When calculating "instantaneous" values, however, the difference between "actual path distance" and "straight line distance" becomes insignificant, because you are using distances for infintesimally small time intervals.


What is the difference between instant and instantaneous?

Instant means Being ready.Instantaneous means spontaneously.


Is there any difference between angular acceleration and radial acceleration?

Yes. A ngular acceleration is to do with something turning. Radial acceleration is linear acceleration perpendicular to the angular acceleration.
