NEET NEET Physics Kinematics

a particle is thrown from the ground with a speed u at angle above the horizontal. The rate of changeof velocity of the psrticle at the highest point of the path is

CBSE IX Physics Motion

why is it necessary for acceleration to be based on velocity but not on speed? why we dont consider the increasing speed of rectilinear motion as acceleration? why is it so in the first place?

JEE Main Physics Kinematics

A particle is at x= -10m at t= 1 sec. and moving with the velocity of 10m/s..particle is found at x=18m at t=3sec. find Acceleration of particle and position of particle at t=5sec.
