Acceleration

I share share a bit about acceleration and how to calculate distances/acceleration/velocity. Acceleration is the rate of change of velocity in time(can both be positive and negative in magnitude i.e retardation). Note: Acceleration is a vector which means having a magnitude and a direction.

Some things that are good to know for speed problems:

v = v0 + at

x= x0 + v0t + at²/2

v²=v0² + 2a(x-x0)

avg v = v + v0 / 2

v= velocity x = distance a = acceleration t= time where y0 denotes the initial y(for x,v)

For this case Acceleration is constant and the movement of the object must be in a straight line. Acceleration from gravity: 9.81m/s towards the center of the Earth.

Acceleration for an object moving in a circular motion:

v^2/r where v is the velocity and r is the radius of the circle the object is moving around.
