The distance travelled by a particle cannot be zero when displacement is not zero because unlike distance which is a scalar, displacement is a vector quantity implying that it has both direction and magnitude.

Negative

If displacement of a particle is zero in a uniform circular motion, then the distance travelled by that particle is not zero, kinetic energy is constant, speed is constant and work done is zero

the displacement is zero.Note that distance travelled would not be zero though. as velocity doesn't signify anything abt distance travelled.speed will give you what distance you travelled.Since average velocity is zero, some component is negetive some positive or no movement at all. whichever case may be, the displacement will be zero.

distance travel led by a particle in a given interval of time is known as displacement. displacement=distance traveled by time taken.Displacement may be zero. it is path length which a particle travels.distance should not be zero.

Distance is the total length travelled where as displacement is the length between where you started and where you are now. example.. If you travel in a circular path, around the whole circle and wind up back where you started. Your displacement will be zero but your distance travelled will be the circumference of the circle.

http://wiki.answers.com/Q/An_object_has_moved_though_a_distance_can_it_have_zero_displacement_it_yes_support_your_answer_with_an_example" Yes If a body travel a distance S from X to Y and return to X then distance travelled is 2S but displacement is zero In a uniform circular motion, the distance travelled by a body in one revolution is 2Ï€r but displacement is zero

No. Distance is never negative, and total distance travelled doesn't decrease during a trip. The distance from A to B is the same as the distance from B to A. Displacement, on the other hand, can be negative, and can decrease during a trip. The displacement from A to B is the same magnitude, but opposite sign, as the displacement from B to A. An example would be if you went from your home to a friend's house 1 mile to the east. After you reach your friend's house, you have travelled a distance of 1 mile and your displacement from your starting position is 1 mile. When you come back home from your friends house, you travel a distance of 1 more mile. Your total distance travelled is now 2 miles, but your displacement from your starting location is zero (because you are back where you started.) Distance does not have direction, and is always positive (or zero). Displacement has direction, and can be negative, positive, or zero.

its magnitude is greater thatn the distance travelled by the object

Distance is greater , because displacement can be zero ,but, distance cannot be zero.

No. Consider the distance between your school and home is 30 km. you would travel to and fro daily, that means you would travel a distance of 60 km. In this scenario, Distance travelled = 60 km whereas, Displacement = 0

Displacement is a vector quantity while distance is a scalar quantity. so in case of displacement, it depends on final position. For example:- If a man walks on a circle, then if he completes one round then his displacement will be zero because the man is at same position as start position. But, his distance travelled will not be zero; it is equal to circumference of the circle.

when the body moves circularly from a point 'A' to a then the displacement will be zero(displacement is the shortest diatance from the initial point to final point) and the distance will not be zero.

The magnitude of displacement is the shortest distance between the initial and final position. In case of a particle completing one full round around a circle the displacement is ZERO. Because the initial and final positions are one and the same

Normally displacement means that some distance has been travelled. If you want to get picky, you can say that is you travel in a closed path, the displacement is zero. In such circumstances, when multiple movments are being combined, one makes is clearer by saying that combining several displacements gives the "net displacement." To get even more picky, we can point out that displacement is a vector defined by the separation of two points. The direction of the displacement vector is the direction of the second point relative to the first and the magnitude of the displacement vector is the magnitude of the distance between the two points. So, since displament is a vector and a vector can have zero length, one can say that you have a zero vector of displacement when no distance has been traveled.

On a three dimensional basis yes it can. Fir instance, if an object is moving directly towards or away from you the angular displacement can be zero though the distance displacement changes.

The distance and displacement are the same when the displacement is parallel to itself or straight. Displacement is a vector and distance is a real number or scalar. If an object is displaced around a circle the displacement is zero and the distance is 2pi r.

No. Distance can be greater than displacement, but not less. The magnitude of the displacement between two points is also the minimum possible distance of a path between the same points.However, the displacement can be zero if the distance is not if the object's starting point and ending point are the same.

It the displacement between two points is zero then they are the same point and so the distance involved in moving between the points can be zero.

Speed is distance by time and velocity is displacement by time. If an object is moving with speed distance can never be zero but displacement can. So we say velocity can be zero.

Yes. If you end up where you started, your displacement is zero, but the distance you travel is the actual amount of ground covered. For example, if you made a round trip of 50 miles, your displacement would be zero miles, but your distance would be 50 miles. This is because the final position and the initial position are the same. Round trips always have a displacement of zero.

some may feel speed and velocity are same terms but both are diffrent,let seehow? Speed=distance travelled/time,that means it depents on how much distance you travelled,its a scalar quantity that means it dont depents on the direction velocity:it depents on diaplacement,ie;velocity=displacement/time,displacement is the measure of smallest distance between mean position and last,its a vecter quatity,so its value can be negetive,+ve,and may zero

Displacement is only the distance from the starting point. As long as you return to where you started, then you can travel 1.0 x 10^999999999999 miles and still have a displacement of zero.

Displacement is a value predicated on the shortest distance between an initial and final position. If a "body" moves a certain distance and returns to its original origin it has not technically traveled any distance based on this definition. The displacement will therefore be zero
