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.
yes
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.
Please ask that more clearly.
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.
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.
No, the average speed will always be between the minimum and maximum speeds.
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).
Voltage divided by the resistance of what ever you want to measure the current in.
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.
Working with very, very round numbers . . .-- The Earth's average distance from the sun is 1 AU.-- Saturn's average distance from the sun is 9 AU.-- The closest together that Earth and Saturn can ever be is 8 AU = 66.5 minutes at light speed.-- The farthest apart that Earth and Saturn can ever be is 10 AU = 83.2 minutes at light speed.
Your average car can reach speeds of up to 230km\h. The highest speed reached ever by a car is 413km\h.
Nobody has ever traveled at the speed of light, and I can promise you that nobody ever will.
