In the equation V = d/t, V is the velocity, d is the distance, and t is the time. Determine the object’s acceleration by dividing the object’s mass by force and multiply the answer by the time it took for it to accelerate. For example, if the object weighs 30 kg and has a force of 15 N applied to it, then the acceleration would be 4 m/s.
Now let’s look at the formula of velocity. As discussed earlier, velocity is a change in objects displacement over time. In simple words, velocity is a measure of how much time an object takes to reach a destination with direction.
Apr 16, 2024 · Velocity = Distance travelled in a given direction/Time Taken. = Displacement/Time Taken. How is velocity different from speed? Example 1. Suppose a person travels 6 km in 2 hours towards east. Speed = Distance/Time = 6/2 = 3 km/Hour. Velocity = Displacement/Time = 6/2 = 3 Km/hour towards east. Example 2.
Apr 5, 2024 · Velocity – Definition, Formula, Units, Equation, Examples. Velocity is the rate of change in displacement with respect to time. The general velocity formula is given by, V = s/t, here s=speed, t= time, and V=velocity. Check units, equation and solved examples.
Jul 4, 2022 · Velocity of a body is defined as the distance travelled by the body in a given direction in unit time. Thus, Solved Examples. Q1. Calculate the speed of z body in m/s and km/hr if it travles 30 kms in 6 hrs. Solution: Distance (s) = 30 km. Time (t) = 6 hrs. speed (in km/hr) = Total distance/Total time = 30/6 = 5 km/hr. 30 km = 30 x 1000m = 30,000 m

Average Velocity is defined as the total displacement travelled by the body in time t. The average velocity is denoted by V av and can be determined using the following formula: \(\begin{array}{l}Average\,Velocity = \frac{Total\,Displacement}{Total\,Time}\end{array} \)
velocity is given by the arithmetic mean of initial velocity and final velocity for a given period of time. That is, average velocity = initialvelocity+finalvelocity 2 Mathematically, v av = u+v 2 (8.2) where v av is the average velocity, u is the initial velocity and v is the final velocity of the object. Speed and velocity have the same units,
Jul 3, 2023 · Distance travelled in a given direction is called as displacement. S.I. unit of velocity is m/s or km/hr. Velocity is a vector quantity. For Example :25km/hr towards north. The direction of velocity is same as the direction of displacement of the body. Uniform velocity.
