Motion of objects, Velocity and Acceleration

STATEMENT-1 : In simple harmonic motion, at extreme position the velocity and acceleration of object is zero. STATEMENT-2 : In simple harmonic motion at mean position?

In uniform circular motion, the velocity vector and acceleration vector are

Discuss the general relations for velocity and acceleration for motion of an one dimension in a plane.

Assertion: For motion in two or three diemensions, velocity and acceleration vecotrs must have any angle between 0^(@) and 90^(@) between them. Reason: For such motion velocity and acceleration of an object is always in the opposite direction.

In case of a uniform circular motion, velocity and acceleration are

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

Assertion : Velocity-time graph for an object in uniform motion along a straight path is a straight line parallel to the time axis. Reason : In uniform motion of an object velocity increases as the square of time elapsed.

Statemetnt - 1 : In circular motion, acceleration may be in any direction relative to the velocity . Statement -2 : Dot product of velocity and acceleration in circular motion may be positive , negative or zero.

Determing whether or not th efollowing quantities can be in the same direction for a simple harmonic motion, (a) displacement and velocity (b) velocity and acceleration © displacement and acceleration.
