Whose value can be zero for a moving particle
1. Displacement
2. Distance
3. Speed
4. None of these

Can distance be zero, even when displacement is not zero ?

The velocity of particle (whose displacement time graph is shown) at t=3 .

If the displacement of a particle is zero, then distance covered by it

The displacement-time graph of a moving particle is shown in the figure. The velocity of the particle is zero at the point ______.

A : Average velocity can be zero, but average speed of a moving body can not be zero in any finite time interval. R : For a moving body displacement can be zero but distance can never be zero.

Which of the following can sometimes be 'zero' for a moving body ? (i) average velocity (ii) distance travelled (iii) average speed (iv) displacement

Distance is a scalar quantity. Displacement is a vector quqntity. The magnitude of displacement is always less than or equal to distance. For a moving body displacement can be zero but distance cannot be zero. Same concept is applicable regarding velocity and speed. Acceleration is the rate of change of velocity. If acceleration is constant, then equations of kinematics are applicable for one dimensional motion under the gravity in which air resistance is considered, then the value of acceleration depends on the density of medium. Each motion is measured with respect of frame of reference. Relative velocity may be greater // smaller to the individual velocities. A particle is moving along the path y=4x^(2) . The distance and displacement from x=1 to x=2 is (nearly) :-
