Can someone explain the rate and acceleration and displacement plzz!!!!Im confused.!! The topic is so wordy. How can i pick out the main key words for the a question?

Considering this:
Displacement = x
Velocity = v
Acceleration = a
In calculus terms
v=dx/dt
a=dv/dt
The rate means the increase/decrease per time i.e. dr/dt
The rate depends on what the question is asking for

the derivative of the displacement function is the velocity
the derivative of the velocity function is the acceleration
x= displacement
.
x= velocity
..
x= acceleration
e.g: displacement = t(sub)2(/sub) + 5t + 6
therefore, velocity = 2t + 5
and acceleration = 2
in this case, the acceleration is a constant, although this is not always the case, depending on the function

sorry, that t(sub)2(/sub) meant t squared
Velocity - rate of change of displacement with respect to time, ie dx/dt
Acceleration - rate of change of velocity with respect to time, ie dv/dt
Acceleration - rate of change of velocity with respect to time, ie dv/dt
Usually the most important words will be the nouns, such as displacement, velocity, acceleration, simple harmonic motion. Pay attention to adjectives and verbs like upwards, downwards, constant, accelerating.

What happen to the object moving to the left of the origin or the right of the origin?
What is that mean?

When somthing is not on the origin we use this to determine the +c when intergrating.
Besides that I wouldnt matter is somthing is left or right of the origin. Its just means that the thingy doesnt start at 0,0

Fanxz guys!!It takes me a while to get the rate, displacement and velocity into my thick head. Yep ! I'll practice more. OKIE DOPkie!!
