how to differentiate between u speed and v speed in a question. I mean how will they project v an u in a question
Answers
Answer:
Speed is directly proportional to distance when time is constant: v ∝ s (t constant)
Speed is inversely proportional to time when distance is constant: v ∝
1
t
(s constant)
Combining these two rules together gives the definition of speed in symbolic form.
v = s
t
☞ This is not the final definition.
Don't like symbols? Well then, here's another way to define speed. Speed is the rate of change of distance with time.
NANBA..
V is Final Velocity
U is Initial Velocity..
When the question is like : The car is moving with a speed of 24m/s.. Then it's U i.e Initial Velocity..
When the question is like : A car came to rest after 15 min then the velocity is V i.e Final Velocity and in this case the final velocity is 0 because the car came to rest wright ..... further doubt ask me I will give many more examples and make you understand..
