A body changes its direction while travelling at constant speed. Does its velocity change?Why?

Answer 1

The velocity of an object is simply total speed in a particular direction. Since velocity is defined as a vector, both speed and direction are required to define it.

So if the body changes direction, its velocity also changes even if it is travelling at constant speed.

Answer 2

Velocity is a vector which includes a direction and magnitude. The direction changed therefore the velocity changes

Answer 3

Certain quantities cannot be fully understood unless the direction is given.

Such quantities are vectors.

If you ask one to move a table in the middle of the room, at once he will ask the direction to which the table is to be moved. Therefore, force is a vector quantity.

Velocity is a vector quantity and it has to be specified by its direction.

Direction is the angle from a reference line.

If the angle between two velocities (vectors) is zero then they are in the same direction.

If the angle between them is 180 degree, they are opposite to each other; in that case if one is positive then the other is negative.

Two vectors will be equal only if both the magnitude and direction are the same.

If any one of the two (either magnitude or direction) is different, then the two vectors are different.

Answer 4

as velocity a vector quanatity which has magnitude and direction, therefore velocity changes with direction though the speed is constant

Answer 5

Velocity is a vector, so any change in any component is the change in velocity.

Vector has two components, Magnitude and the Direction.

Answer 6

yes its velocity is changed.while defining velocity both magnitude & direction are mentioned.so when the direction is changed the velocity is also changed.

Answer 7

Yes it does, because velocity is both speed and direction.

Answer 8

Any time an merchandise adjustments route, there's a stress appearing on it. (otherwise it ought to proceed interior a similar route without replace) each and every time there is stress, this is mass X acceleration. it will be adverse (if the route is opposite of ways the article is already going), although this is going to reason some type of acceleration.. no matter if this is not replacing the speed of the article, likely, that is coming from yet another route. as an social gathering, in the journey that your merchandise A is going north at 6 m/s, there ought to without word look a stress pushing A to the West at 10 m/s. because west is neither South (opposite direction) or North (same route), that (perpendicular) stress does not reason the speed going North to regulate. it ought to replace the route and % going West (from 0 m/s to ten m/s). it truly is acceleration. in case you play basketball, this happens each and each and every of the time once you block the ball. You shoot the ball (at 6m/s of route :) to the ring, yet some one pushes your ball 2 seconds later to the left ( i.e. they have speeded up that ball from 0 to ten m/s in a perpendicular route). Your ball keeps to bypass in the route of the ring in the front of you at 6 m/s, yet now that is likewise shifting at 10 m/s to the left, so it misses the ring thoroughly, and finally ends up someplace interior the better left nook of the court docket. (the opposing crew cheers...)

Answer 9

i think the body need force to change it direction .
first nuton low (( the body still move in same direction and speed if there no force effect on it ))
so we get the force from the force that accrue the movement
so it will be decrease so speed will decrease too

Answer 10

velocity may be zero at the peak point when we throw a body in the upward direction..
