When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.

∙ 13y agoWhen an object is in constant motion (when there is no acceleration). At any point in that motion the average and instantaneous velocities will be the same.
Wiki User
∙ 13y agoYes. In smooth linear motion, the average speed and the instantaneous speed are equal.
Wiki User
∙ 13y agoYes, if the instantanious velocity is constant.

Can instantaneous speed ever be greater than its average speed?
yes
Does the instantaneous speed ever equal the magnitude of its average velocity?
Yes. For a start, this happens when the object moves at a constant velocity. Also, if moving in a straight line, even if the object changes speed there must needs be a moment when its instantaneous speed is equal to its average speed - since it cannot change speed suddenly, it must do so gradually.
Why is during a trip a car instantaneous speed can ever be greater than its average speed?
Please ask that more clearly.
Can instantaneous speed and average speed ever be different for a moving object?
Of course. When you're driving on the Interstate and you see a State Police cruiser coming up behind you, you stomp the brake and slow way down to the speed limit. Now your instantaneous speed is only the speed limit. You feel like you're crawling, you can't stand it, and as soon as you're sure he can't see you and doesn't care, you let your car come back up to normal speed again. Your average speed for the trip, or for any whole hour that includes that little episode, is comfortably in excess of the limit, although your instantaneous speed at any instant during those few minutes was exactly the posted limit.
Explain whether during a trips cars instantaneous speed can ever be greater than its average speed?
Of course it can.If you live 10 miles from your job, and you hit 100 miles per hour on the way to the office,but stop for coffee for an hour during the trip, I guarantee your average speed is less than100 mph.
Can the average speed ever exceed the maximum speed for a trip?
No, the average speed will always be between the minimum and maximum speeds.
What is the difference between average speed and top speed?
Average speed is a value of all the speeds you have travelled at over a certain length of time. Top speed is the absolute highest or fastest speed that you have ever reached. (A one time speed value).
How can instantaneous current values be determined?
Voltage divided by the resistance of what ever you want to measure the current in.
When you are describing the rate that a race car goes around a track should you use the term speed or velocity to describe the motion?
Since velocity is speed with direction, you would use speed in reference to average rate of change of position, since the direction keeps changing. You can use velocity in reference to instantaneous speed, since a car is going in a specific direction at each instant in time.Examples:80 km/h is a speed.80 km/h due north is a velocity.
What is the Average speed of 10 meters in 6 seconds?
Average speed is total distance divided by total time. Hence 10 metres in 6 seconds is an average speed of (10/6) = 2.66666 m/s. Notice the units of speed - if you ever forget that speed is distance over time, just remember speed's units is something like metres per second, miles per hour etc. "per" means divided by.
What is the fastest recorded speed ever on skeleton?
the fastest speed ever is 12874.97 mph
Is constant acceleration same as constant speed?
no because constant acceleration describes and object speeding up at an equal rate wheras constant speed describes an object travelling at the same speed over time. By the way i h8 physics don't ever do it
