Average velocity in kinematics refers to the total displacement of an object divided by the time it takes to cover that displacement. It is a measure of the rate of change of the position of an object and can be calculated using the following formula:
V_avg = ΔS/Δt
Where:
V_avg is the average velocity
ΔS is the change in position or displacement
Δt is the change in time
In cases where the velocity of an object changes, the average velocity can be calculated as the total displacement divided by the total time it takes to cover that displacement. The average velocity can be different from the instantaneously velocity of an object at a particular moment in time.
Average Velocity with Variation in S:
When the displacement of an object changes over time, the average velocity can be calculated by dividing the change in displacement by the change in time.
Average Velocity with Variation in V:
When the velocity of an object changes over time, the average velocity can be calculated by taking the arithmetic mean of the initial and final velocities and dividing by 2.
V_avg = (V_initial + V_final)/2
Average Velocity with Variation in S and V:
When both the displacement and velocity of an object change over time, the average velocity can be calculated by dividing the total displacement by the total time. This calculation takes into account both the initial velocity and the change in velocity over time.
