Question

PLEASE! I NEED HELP! Can someone explain me what differentiation exactly means in physics? I'm really confused. When and why do we use differentiation to find instant velocity...Please help! Can you link me to a helpful youtube video as well for explanation?

ok

Answer 5

Instantaneous velocity is velocity at every point in time. This can only be found from the derivative of the position function. \[v(t) = x \prime (t)\] Average velocity, on the other hand can be found with two points on the position versus time curve. \[v = \frac{ x _{f}-x _{i} }{ t _{f}-t _{i} }\] Intantaneous velocity is velocity and ONE point in time. Average velocity is velocity between TWO points in time.
