what is the main difference between instantaneous speed and constant speed?
480158
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.

Velocity is one kind of rate of change. It is the rate of change of position with respect to time. Rate of change is more general and includes velocity as one example. The word "instantaneous" has does not alter any of this.

There are two important types of constant motion: constant speed and constant acceleration. Constant speed means the speed does not change at all for each second of the motion. ... Constant acceleration means that the speed increases by the same constant rate for each second of the motion.

Average acceleration is the change of velocity over a period of time. Instantaneous acceleration is the change of velocity over an instance of time. Constant or uniform acceleration is when the velocity changes the same amount in every equal time period.

The initial speed of an object simply refers to how fast it is moving when it begins its motion (it doesn't take into account whether it is travelling north, south, left, right, etc.). It is a scalar. The initial velocity of an object, on the other hand, has both a magnitude (speed) and a direction (ie: to the left).

Speed and velocity both represent a way to measure the change in position of an object relative to time. In fact, for a straight line motion, the speed and velocity of an object are the same (since distance and displacement will be the same). Speed and velocity are measured in the same units: meters per second or m/s.

Constant acceleration refers to motion where the speed increases by the same amount each second. The most notable and important example is free fall. When an object is thrown or dropped, it experiences a constant acceleration due to gravity, which has a constant value of approximately 10 meters per second squared.

A constant velocity is where both the magnitude and the direction remains fixed for the concerned time period, whereas in uniform velocity, the magnitude remains fixed but the direction may or may not change over the time period. A "constant" velocity is always "uniform", but the vice-versa is not always true !

Speed commonly refers to the constant rate of change over a distance. That is, it is commonly associated with movement across a distance. ... Rate is a description of change over time. It doesn't have to do with distance (as with speed).

The direction of instantaneous velocity at any time gives the direction of motion of a particle at that point in time. The magnitude of instantaneous velocity equals the instantaneous speed. This happens because, for an infinitesimally small time interval, the motion of a particle can be approximated to be uniform.

As adjectives the difference between momentary and instantaneous. is that momentary is for only a moment while instantaneous is occurring]], [[arise|arising, or functioning without any delay; happening within an imperceptibly brief period of time.

Acceleration is rate of change of speed, where the speed itself is changing per unit time. ... Now an object moving at constant speed has zero rate of change of speed obviously, and hence the acceleration is zero. An example is an object moving in space with constant speed.

The speed is the time rate of change of the distance. If 'D' is the distance of an object in some time 'T', the speed is equal to, s = D/T. It has the same units as velocity.

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.

The speed is the time rate of change of the distance. If 'D' is the distance of an object in some time 'T', the speed is equal to, s = D/T. It has the same units as velocity. let us solve some examples, we will introduce the formulae as we go along.

Sometimes an accelerating object will change its velocity by the same amount each second. ... This is referred to as a constant acceleration since the velocity is changing by a constant amount each second. An object with a constant acceleration should not be confused with an object with a constant velocity.

Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the same as the time to return to its launch position.
