If you travel against the direction, we consider velocity as negative, while speed always remains positive. The symbol for representing the velocity is the same as that of your GPS tracking device. Speed Total distance travelled divided by time spent. 120 + 210 330 km total distance travelled. When we measure the time it takes for an object to cover a given distance, we can calculate the average speed of the object for that.

So, in two hours, distance travelled 260 120 km, and in three hours, distance travelled 370 210 km. The formula to find average velocity is as follows:Īverage velocity v av = (40 + 90)/2 = 65 m/s. ANS- We already know that distance equals speed times time. If we have to calculate the velocity at an instant, then the formula turns to the instantaneous velocity formula.Įxample: A boy walks with an initial velocity of 40 m/s and he reaches his destination at 90 m/s. The speed of an object is found out by dividing the distance that the object covers by the time in which the object takes to cover this distance. = (Final position - initial position)/(end time - starting time) Acceleration equation as a derivative if newton’s law of motion that is F ma. The formula for average speed is found by calculating the ratio of the total distance traveled by the body to the time taken to cover that distance. Īnother equation for the average velocity is: Average acceleration equation that is acceleration final velocity initial velocity / time change in velocity / time. When speed increases, time decreases, and vice versa. Speed and time are inversely proportional to each other. Speed, distance and time are always inter-related to each other. An online physics calculator which helps to calculate the average speed based on the given time and distance values. ,n in a given time ‘t’, then finding average velocity becomes easy by using the following average velocity equation: Average Speed Calculator using Distance and Time. So, if a body travels various displacements viz: s 1, s 2, s 3.

Average velocity is the expression of total displacements possessed by a body in time ‘t’.
