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

It happens when an object is moving at constant speed along a curved path (like a circular motion at constant speed).


Speed only tells how fast is moving any object, but velocity is determined by speed and the direction of speed. In a curve path an object that is moving at constant speed, the direction is changing all the time.Can an object have a constant speed and at the same time a varying velocity?
Yes. Because velocity is speed that has a definite direction. 20 mph is a speed but 20 mph due east is a velocity, so by varying your direction you also vary your velocity. If traveling in a straight line, velocity is a simple equation with vrepresenting velocity, s the speed and t the the time interval (';per hour'; in most cases).


Looks like this


v=s/t (within a defined direction or vector)





Speed, within a determined vector or direction, is a measurement of velocity.





To get really confused, go to wikipedia and enter velocity and read the entire article. G'day!Can an object have a constant speed and at the same time a varying velocity?
An object's velocity is defined as its speed and direction. Since it is possible for an object to have a constant speed while changing direction; the answer is yes it is possible.
Speed is a scalar value and velocity can be assigned direction. Let us say that an object is traveling along a line, any line. It's speed along that line is given by the distance covered along that straght line divided by the time it takes to travel along that distance.





Now, let's say that object is also moving perpendicular to that same line, going away from the line and then returning to go in the opposite direction perpendicular only to return again. It is oscillating about the line as it travels with the same speed described above.





The speed remains the same for both scenarios in the direction of the line. The velocity, however, does change. The Velocity would be defined in the first scenario as the vector equivalant of the speed. So, speed and velocity would be the same value in the first scenario. In the second scenario, the velocity would be the same as in the first scenaio for the direction along the line, PLUS the added velocity of the motion perpendicular to our original line, which would be some function which I am sure you will be encountering soon.





Hope this helps.
Yes. If the object has a constant speed but it is changing its DIRECTION while moving, then its velocity is changing; Velocity is a vector. Vectors have magnitude (number value and a unit) and a direction.

What is the speed of a free falling object?

For steady state, it is whatever speed that gives air-resistance equal to weight and it's called terminal velocity.





For ';air-resistance'; read any-fluid resistance. If falling within a vacuum there is no limit to the speed.





120mph is the figure quoted for an average human being, in averagely baggy clothing (and the person's attitude will affect things a lot), in air.

.What is the speed of a free falling object?
9.8 meters per second squared is the acceleration of an free falling object. So many round that to 10 meters a second. And of course speed is the total distance over a period of time. So say for instance an object takes 6 seconds to fall, each second is about 10 meters, so 6 seconds times 10 meters is 60 meters per second is the top speed of the free falling object.What is the speed of a free falling object?
Roughly 120 miles per hour. I believe that equates to 30 feet per second squared.

1: A carrot lubricated with grapeseed oil: Rub it very quickly over your clit.


2: Drops of water: Drop drops of water on your clit.


3: Showerhead: Take the showerhead and point it up to your clit.


4: Hands: There are many ways. Watch a video on YouTube called C Spot Orgasms. There are more such as G, A, U and S stop orgasms.





Ok! That was my cousin KB! He is a female orgasm expert.

In dealing with Java: What is the relationship between a client of an object and the object's public members?

It's the only problem that I can't answer on this pre-lab assignment, I have for my programming fundamentals class. It's due in 2.5 hours :(In dealing with Java: What is the relationship between a client of an object and the object's public members?
class MyObject {


public String isdnNum;


private double price;


// constructor


public MyObject( String isdn, double amt ) {


isdnNum = isdn;


price = amt;


}


// method


public String getPrice() {


return price;


}


}


In the above example client can only see the public members.


MyObject obj = new MyObject( ';123456';, 9.95 );





client can see the isdn as obj.isdnNum;


client cannot see price as obj.price, instead


double thePrice = obj.getPrice();





this example is very simple, you normally would not expose price that way, but it shows if the value 'price' is private, the only access is to use a member.method() and programmers carefully code the access modifiers: default, public, private, protected

  • How do I find the mass of an object given its density and volume?

    m = d/v





    So, you divide your density by your volume.














    Hope I helpedd! =)How do I find the mass of an object given its density and volume?
    density=mass/volume

    What could increase the gravitational force of an object, besides mass?

    DISTANCE OF THE BODY FROM NEIGHBOURING ONESWhat could increase the gravitational force of an object, besides mass?
    the gravitational constant . except mass of two body, the gravitational constant also important . F= GMm/r^2


    so the distance between two body also important :-)

    Can an object of a superclass access members declared in a subclass?

    can an object of a superclass access members declared in a subclass?Can an object of a superclass access members declared in a subclass?
    No, a superclass (base class) could not even know about members declared in a descendant class.
