what down formula for velocity and its unit
Answers
Answer:
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt.
Answer:
Velocity formula = displacement ÷ time
Displacement = final position – initial position or change in position
Time = taken to cover the distance.
Example 1 - Suppose there is an object traveled a distance of 10 meters in the left direction and the time taken by the object is 2 minutes. Find the velocity of the object.
Solution:
Now recall the formula which is velocity = displacement ÷ time
v = a / t
Now put the values in the formula. But first of all change minutes into time by multiplying minutes by 60.
Time in seconds = time in minutes × number of seconds in a minute
ts = 2 × 60 = 120 s
So, time in seconds is 120 s
v = 10 / 120
v = 0.08 m/s
The velocity of the object is 0.08 m/s.
Example 2 - Now let’s discuss another problem where we know the value of velocity and time and we have to calculate displacement. The value of velocity and time is 1.5 m/s and time taken is 100 seconds. Find the value of displacement.
Solution:
Now recall the formula which is velocity = displacement ÷ time
v = a / t
Now put the value in the formula
v = a or a / t
1.5 = a ÷ 100
1.5 × 100 = a or
a = 1.5 × 100 = 150 m
The displacement is 150 m.
