The difference isdistance is the total path length covered by an bodytime is the total time taken to complete a given piece of work. What is the difference between distance and time?Īnswer. Recall that velocity is a vector-it has both magnitude and direction. Is velocity in m/s divided by time in S?īecause acceleration is velocity in m/s divided by time in s, the SI units for acceleration are m/s2, meters per second squared or meters per second per second, which literally means by how many meters per second the velocity changes every second. Such a time interval is called the elapsed time. The total distance traveled divided by the total time of travel is the. That is, moving from one place to another happens in the course of time. The motion of an object takes time to occur. The speedometer of a car measures the instantaneous speed of the car. Answer Answer: (b) Both assertion and reason are true but reason is not the correct explanation of assertion. What is the elapsed time of an object from one point to another? Reason : Average speed is equal to the total distance covered by an object divided by the total time taken.
(R ):The average speed of an object may be equal to arithmetic mean of.
S, equals, v, t, minus, one half, a, t, squared,s=vt−21at2 (A):Average speed is equal to total distance travelled divided by total time taken. (a) Assertion is correct, reason is correct reason is a correct explanation for assertion.
Reason : Average velocity is equal to total displacement per total time taken. Since the three segments are all the same length, the triathlete's average speed is the harmonic mean of the three given rates. Answer (1 of 5): The average of some numbers is the sum of the quantities and divided by the number of them, but you only have distance travelled and time taken, so you need to do it another way. Assertion : The speedometer of an automobile measure the average speed of the automobile.
The total distance is, and the total time is. Calculate its speed in m/s.S, equals, u, t, plus, one half, a, t, squared,s=ut+21at2 Average speed is total distance divided by total time. A common example involves converting a speed from kilometres per hour (km/h) to metres per second (m/s). Sometimes calculations require a conversion from one set of units to another.
Calculate the distance travelled in this time.ĭistance travelled = 300 m Converting between units
