Which of the following statement is correct regarding velocity and speed of a moving body ?

(a) velocity of a moving body is always higher than its speed

(b) speed of a moving body is always higher than its velocity

(c) speed of a moving body is its velocity in a given direction

(d) velocity of a moving body is its speed in a given direction

Q.

Mark the correct statement(s)
(1) If speed of a body is varying, its velocity must be varying and it must have non-zero acceleration.

(2) If velocity of a body is varying, its speed must be varying.

(3) A body moving with varying velocity may have constant speed.

(4) A body moving with varying speed may have constant velocity, if its direction of motion remains constant.

Q. Consider the given statements and select the option which correctly identifies the true $\left(T\right)$ and false $\left(F\right)$ statements.
(i) Distance is the magnitude of displacement in all cases.
(ii) When a body moves with uniform speed, then the average speed is same as instantaneous speed.
(iii) Average speed is greater than the average velocity if a body is moving in a straight line without reversing its direction.
(iv) When a body moves with constant velocity, the average velocity is zero.

Q.

If a body travels at a uniform velocity of $u$ for $t$ seconds and at a different velocity of $v$ for the next $t$ seconds, what is the total distance covered in $2t$ seconds?

Q. (1) : If a body moving in a circular path has a constant speed, then there is no force acting on it.
(2) : The direction of the velocity vector of a body moving in a circular path is changing.
