Generally it is a Yes. Instantaneous velocity is the exact velocity at a particular time in the course of the movement. However, average velocity is the average of all the instantaneous velocity over a period of time. It is also known as speed in everyday life. As a result, the movement of an object over a time period under varying velocity denotes a varying instantaneous velocity which could be different from the average velocity. It is however, possible that the instantaneous velocity equates to the average velocity at a certain point over the duration of movement. For example, a ball is traveling at instantaneous velocity of 99m/s at t=1s , 100m/s at t=2s and 101m/s at t=3s. the average velocity over the 3s period is hence 100m/s which coincides with the instantaneous speed at t=2s.

0Average velocity is the average of the velocty of entire motion where as instantaneous velocity is the velocity at an instant, it may be a function of time or displacement.

No. If it its moving at constant velocity, its instantaneous velocity would be the same as its constant velocity.

No. Its velocity, average velocity and instantanous velocity will all be the same at any (or every) time an investigator makes an observation.

If a 5 mile stretch of a bus journey lasts 15 minutes, then the average speed over this stretch was 20mph. But undoubtedly the bus achieved greater speeds than this, and it also spent time sitting still in queues. So the simple answer to the question is 'yes'. Less trivially and more interestingly: unless velocity is actually constant, then an object's average velocity over a finite time interval - and hence any empirical measurement of its speed - must (nearly always) differ from the instantaneous velocity. As the time period grow closer to zero, the measured velocity will converge on the instantaneous figure, but will never reach it.

The average speed of a car is how fast it averages over a span of time. Instantaneous speed is how fast the car is moving at any given time which is measured using a real-time speedometer.

Acceleration is the rate of change of velocity.

Acceleration is the rate at which velocity is changing.

Velocity indicates direction in addition to speed.

Simply put,acceleration is got when velocity changes with time while velocity is when speed changes with time.

Speed and velocity are similar because they are both measures of quantity that involve motion. They differ because speed is a scalar quantity while velocity is a vector.

A projectile has an initial forward velocity.

When a direction is specified, it is called velocity. When the direction is not specified, it is called a speed. (That's the difference between a vector and a scalar.)

One can think of a racing car making one lap around a car racing track. During the race the speedometer will be indicating the speed the car has at a given moment. This is the "instantaneous speed" v(t). It is a function of time, meaning that it varies in time. If we now take the length of the track L and divide it by the time t the car took to accomplish one lap, then we have the average speed, vav = L/t, of the car during a lap around the track.

Velocity is a speed and its direction. -- "30 miles per hour" is a speed -- "30 miles per hour north" is a velocity -- "30 mph north" and "30 mph east" are equal speeds but different velocities.

sudden load differ from impact load by the velocity of loading

A projectile is a free-falling object that also has some horizontal velocity.

In mechanics, an impact refers to the shock or force produced when two or more bodies collide. High and low velocity impacts basically differ in the speed at which the objects collided. Low velocity impact is normally under 30 mph while high velocity impact is above.

Velocity is distance the fluid travels per unit time.velocity = distance / timeFlow rate (also Volumetric flow rate) is volume of fluid, which passes per unit time.flow rate = volume / time

Velocity is a vector measurement, it has both a speed quantity, but also includes direction. Speed is a scalar measurement, it only concerns with the how fast the object is moving, not its direction

Velocity is speed in a particular direction. Usually miles per hour or metres pet second . So that means that velocity is distance divided by time. Displacement is a distance measured in miles, metres etc. And is the difference between the starting position and the finishing position.

because water has higher viscosity than air so resisting the movement of the body in it more than air so decreasing the velocity

depending on the wind velocity and the surrounding elements the time would differ per individual. traveling at an average speed of 14.8 MPH you could complete this grueling task in 27 hours. GOOD LUCK!

The average can greatly differ based on location and economic conditions.

Seismic wave velocity is mostly dependent on the material they travel through (things like magnitude do not affect wave velocity). As the earth is relatively uniform, there is virtually no deviation in earthquake 'speed'. (Wave velocity will differ depending on phase, depth, etc. - but that's different.)

Velocity (distance-time), Magnitude (volume) and Density (echo/harmonic) signatures differ.
