For any particle moving with some velocity (vecv) & acceleration (veca) , tangential acceleration & normal acceleration are defined as follows. Tangential acceleration - The component of acceleration in the direction of velocity. Normal acceleration - The component of acceleration in the direction perpendicular to velocity. If at a given instant, velocity & acceleration of a particle are given by . vecc=4hati +3hatj vaca=10hati+15hatj+20hatk Find the tangential acceleration of the particle at the given instant :-

Assertion: In projectile motion, the acceleration is constant in both magnitude and direction but the velocity changes in both magnitude and direction. Reason: When a force or accelration is acting in an oblique direction to the direction of velocity then both magnitude and direction of the velocity may be changed.
What is direction of angular velocity for a rigid body?
Body cavity of cockroach is called-
For body moving with uniform acceleration a change in velocity of body in Deltat time interval will be …... .
Will the acceleration increase or decrease with increase in velocity ?
Give the direction of acceleration of SHM particle.
A body is executing circular motion in the vertical plane containing directions. If the direction of velocity (oversetrightarrow(v)) at the top most point is towards west, what is the direction of angular velocity (oversetrightarrow(omega))?
In your everyday life you come across a range of motions in which (a) acceleration is in the direction of motion. (b) acceleration is against the direction of motion. (c) acceleration is uniform. (d) acceleration is non-uniform. Can you identify one example each of the above type of motion ?
