When an object moves with inconstant velocity does its average velocity differ from its instantaneous velocity?
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.

How can a graph showing deceleration differ from a graph showing acceleration?
A graph showing deceleration typically features a negative slope, indicating a reduction in velocity over time, while a graph showing acceleration displays a positive slope, indicating an increase in velocity. In a deceleration graph, the values of velocity decrease, often approaching zero, while in an acceleration graph, the velocity values increase. The shapes of the curves can also differ; a deceleration graph may show a smooth decline, while an acceleration graph might show a steep incline. Additionally, the axes may represent time and velocity in both cases, but the interpretation differs based on the direction of change.
What is the width of average 4 lane street?
An "average" traffic lane is 11-12 feet wide, so an "average" 4 lane street would be 44-48 feet wide. I have found most cities to differ in this, so it's almost impossible to find an "average"
How does the slope differ from average rate of change?
They are the same for a straight line but for any curve, the slope will change from point to point whereas the average rate of change (between two points) will remain the same.
How is thermal energy different from temperature How are they similar?
temperatures differ from thermal energy because differ because thermal energy is the total energy of all particles in an object and temperature is a measure of the average energy of random motion of particles of matter.
How does constant velocity differ from constant acceleration?
Constant velocity is a measure of distance traveled per unit of time at a uniform speed, such as miles per hour or feet per second. Constant acceleration is a measure of a continuing increase in velocity per unit of time, as when a car speeds up from 30 miles per hour to 40 miles per hour in 5 seconds, then from 40 miles per hour to 50 miles per hour during the next 5 seconds. It will then have had a constant acceleration of 10 miles per hour per 5 seconds.
What is a instantaneous velocity?
Instantaneous velocity is the velocity of an object at a specific instant in time. It is the rate of change of position of an object with respect to time at that exact moment. This instant velocity may differ from the average velocity over a given time interval.
How does average velocity differ from instsntaneous velocity?
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.
How does a car's average speed differ it's instantaneous speed?
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.
To justify with calculation average speed is equal to instantaneous speed?
Average speed is calculated by dividing the total distance traveled by the total time taken. Instantaneous speed, on the other hand, is the speed at a specific moment in time. They can be equal in situations where speed is constant over time, but in most cases, they will differ because instantaneous speed can vary as the object moves.
Is the average speed equal to the magnitude of the average velocity justify your answer?
Yes usually and no rarely, velocity is defined as a vector, having both a direction and a magnitude (which is speed in the case of velocity). For instance 100 mph (speed) east (0o) (direction). In this form it is easy to see that the magnitude is 100 mph but mathematically to determine the magnitude of a vector you would divide the vector by its direction. 100 mph 0o / 0o = 100 mph Average speed and average velocity share the same relationship as instantaneous speed and instantaneous velocity so divide out the average direction from your average velocity to determine your average speed. If this is over a time period and you know the beginning and ending places in space your averages will simply be the difference from the starting to the ending places. So yes so long as you define speed to actually be the magnitude of the vector. However, if speed is taken without direction over time it may become something different. If an object travels along a vector with a negative magnitude its speed will not be negative but its vector magnitude will. Ex: A car travelling in reverse still has a positive speed but a compass will show it to be heading in the opposite direction of travel, a negative vector value...
How does a car average speed differ from its instantaneous apeed?
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.
If the reading on the odometer of a vehicle in the beginning of a trip and after minutes were km and km respectively will the reading on the speedometer show this velocity were the vehicle i?
To determine if the speedometer reading reflects the calculated velocity, you need to know the distance covered and the time taken. If the odometer readings indicate a distance traveled and you divide that by the total time of the trip (in hours), you can calculate the average speed. The speedometer shows the vehicle's instantaneous speed, which can fluctuate based on acceleration or deceleration. If your average speed aligns with what the speedometer indicates at a specific moment, then yes, it reflects the velocity; otherwise, it may differ.
How does acceleration and velocity differ?
Acceleration is the rate at which velocity is changing.
Does velocity differ from acceleration?
Acceleration is the rate of change of velocity.
