Yes. In smooth linear motion, the average speed and the instantaneous speed are equal.
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. The instantaneous can be less than the average: Your average speed from your home to your job is probably somewhere between 5 and 40 miles per hour. Your instantaneous speed when you're stopped at red light along the way is zero. The instantaneous can be more than the average: If you have to drive home in a blizzard, or during rush hour on the LA Freeway, you may have to crawl bumper to bumper for an hour, and your average speed for the trip may be only 5 miles per hour. But your instantaneous speed as you enter the freeway, or when you finally reach the street where you live, may be 10 miles per hour.
Yes. For example, a vehicle that travels 25 mph for an hour and then 75 mph for an hour has an average speed of 50 mph though it spent half that time traveling much faster.
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.
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.
No because it would imply that some distance was covered in 0 time. That is that the instantaneous speed was infinite.
No, the average speed will always be between the minimum and maximum speeds.
Of course. If you drive on a long-distance trip for 10 hours each day and spend the remaining 14 hours in a motel, then the instantaneous 70 or 75 mph that you frequently hit while on the interstate during the day is most definitely greater than your average speed for the trip.
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.
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.
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.
the average speed is 85 miles per hour^^^ Who ever posted that is incorrect. the average pitch speed of a VARSITY HS pitcher would be cruising 77-80, and topping out at 82 MPH. keep in mind, that those averages span all 4 years, as the average for just the varsity.
The average speed of a soccer ball when kicked by David Beckham is under 91 miles per hour. His top speed was recorded at 97 miles per hour while the top speed ever recorded was about 138 miles per hour.
90-92 is considered average for a mlb pitcher. randy Johnson was recorded throwing 103 and that is the highest ever recorded
Paul Rabil, of the Boston Cannons, has clocked his shot at 113mph. That was the fastest shot ever shot. The average lacrosse speed in the MLL is in the 90's
the fastest speed ever is 12874.97 mph
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.
They are equal.. which ever one has harder wheels and faster bearings will be the faster of the two. Less friction = more 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
Nobody has ever traveled at the speed of light, and I can promise you that nobody ever will.
