Motion in One Dimension – Important Points Regarding Acceleration
Important Points Regarding Acceleration (i) There is no definite relation between the direction of velocity vector and the direction of acceleration vector i.e. angle between velocity and acceleration may have any value. For Example (a) In case of projectile motion. (figure) The angle between acceleration and velocity is at O, at A and at…

Motion in One Dimension – Acceleration
Acceleration It is defined as the rate of change of velocity and it is a vector quantity (i) Instantaneous acceleration : It is defined as the acceleration of a body at some particular instant. Instantaneous acceleration = = (ii) Average acceleration : = = The direction of average acceleration is the direction…
