Kinematics - Instantaneous Velocity And Acceleration

Assertion : Kinematic equations are exact and are always correct. Reason : The definitions of instantaneous velocity and acceleration are true only for motion in which the magnitude and direction of acceleration are constant during the course of motion.

What is instantaneous velocity?

Basics: position, displacement, distance, average velocity, average acceleration,Instantaneous velocity and acceleration, Uniform motion

The velocity varies with time as vecv = ahati + bthatj , where a and b are positive constants. The magnitude of instantaneous velocity and acceleration would be

Position Vector|| Instantaneous Velocity|| Speed Acceleration|| Average Velocity|| Average Speed ||Turning Point

The phase difference between the instantaneous Velocity and acceleration of a particle executing simple harmonic motion is

In the given find the and acceleration of B if instantaneous velocity and acceleration of A are as shown in the .

Derive an expression for instantaneous velocity and acceleration of a particle executing simple harmonic motion.
