Can an object have a constant speed and a varying velocity at the same time? Explain.?

Answer 1

Yes; anything moving UNIFORMLY in a circle, that is at a constant speed in a circle, satisfies this condition.

Speed is the magnitude (or size) of a velocity, without concern for the DIRECTION of that velocity.

However, any VELOCITY has both a speed AND a direction. A velocity is changing if EITHER of those attributes (or both) is (are) changing. Thus, if the DIRECTION of a velocity is changing, then that VELOCITY is changing, EVEN IF the speed remains the same.

Live long and prosper.

Answer 2

Yes. Speed is a scaler; velocity a vector. If an object is moving in a non straight line but at the same rate, then the speed would be constant but the velocity would not because the direction is changing. Velocity = speed in some direction. Basically, speed has one variable, velocity two (one of which is speed).

Answer 3

Yes, because velocity has two componants; speed and direction. A car turning at 25 mph will have a constant speed, but the velocity will be changing as long as it is turning.

Answer 4

velocity is a vector quantity so it includes direction. speed is scalar so only magnitude comes into play. My assumption is that yes velocity can change as long as the magnitude is unchanged

Answer 5

you're magnificent. the factor is that one and all products are interior the commencing up speeded up via gravity at precisely the comparable fee inspite of mass in spite of the fact that via fact the consequence of wind resistance starts off to dominate they attain particular terminal velocities and for a great-unfold shape the terminal velocity is dependant on mass. the appropriate thank you to sense approximately it is in words of Forces. tension = Mass x Acceleration , subsequently a great mass accelerating on an identical rate as a small mass (ie in gravity) has a lots greaterpersistent working on it. Air resistance creates a tension interior the different direction this is simplest dependant on the style and the speed. So products will shop getting swifter till the two forces stability and on account that heavy products have greaterpersistent from gravity, they'll could desire to bypass swifter in the previous than air resistance suits it. As an aside, I by no skill fairly offered why all products develop up on the equivalent fee in gravity. One physique of suggestions to contemplate approximately that's that while you have got 2 comparable products they the two fall on an identical fee. once then you grow to be a member of them mutually one and all nonetheless falls on the comparable value in spite of the blended technique being heavier. the different course to work out it is to contemplate inertia. while you attempt to flow a heavy merchandise it resists any exchange in velocity and it isn't any diverse for products falling below gravity They get a bigger charm via their bigger mass in spite of the fact that the two they're greater beneficial reluctant to develop up, additionally via their mass.
