What else can I help you with?
Can a body have constant speed as well as variable velocity?
No, constant speed implies that the body is moving at a consistent rate, while variable velocity means the direction of motion is changing. It is not possible for a body to have both constant speed and variable velocity simultaneously.
Why is the acceleration of a body moving uniformly in a circle directed towards the centre?
The acceleration of a body moving uniformly in a circle is directed towards the center of the circle because it is constantly changing direction due to the change in velocity (even though the speed is constant). This change in direction results in a centripetal acceleration that keeps the body moving in a circular path.
What is the condition in which a body moving with uniform speed has a variable velocity?
The condition in which a body moving with uniform speed has a variable velocity is when the direction of motion changes even though the speed remains constant. This means that the object is accelerating, even though its speed does not change.
Why is acceleration of a body moving uniformaly in a circle directed toward the centre?
The acceleration of a body moving uniformly in a circle is directed towards the center because the velocity of the body is constantly changing direction, even though its speed remains constant. This change in direction of the velocity results in a centripetal acceleration that is required to keep the body moving in a circular path.
Can an objeact have constant speed and but variable velocity?
Speed is a scalar quantity while velocity is a vector quantity.It is possible that an object can have constant speed but if speed is constant while direction of motion is changing constantly then it means that body has variable velocity.An example of this phenomena is a body moving in a circle whose speed is constant but velocity is changing every instant due to change in direction at every instant.
What would be the shape of a speed time graph of a body moving with variable speed?
If a body is moving with variable speed, then the only thing you can say aboutits speed/time graph is that the graph is not a straight, horizontal line.
Can a body have constant speed as well as variable velocity?
No, constant speed implies that the body is moving at a consistent rate, while variable velocity means the direction of motion is changing. It is not possible for a body to have both constant speed and variable velocity simultaneously.
How much work may be done on a body that moves in a circle with constant speed?
If there's a body moving in a circle with constant speed, and you come along and do work on it, then either its speed will change, or it will depart from the circle, or both. The force that's keeping it on the circular path is not doing any work on it.
Why is the acceleration of a body moving uniformly in a circle directed towards the centre?
The acceleration of a body moving uniformly in a circle is directed towards the center of the circle because it is constantly changing direction due to the change in velocity (even though the speed is constant). This change in direction results in a centripetal acceleration that keeps the body moving in a circular path.
What is the condition in which a body moving with uniform speed has a variable velocity?
The condition in which a body moving with uniform speed has a variable velocity is when the direction of motion changes even though the speed remains constant. This means that the object is accelerating, even though its speed does not change.
What will be acceleration of a car moving in a circular motion with constant speed.?
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
Can the average speed of a body be zero and can the average velocity of a moving body be zero?
Since speed is a scalar quantity, the only way the average speed can be zero is if the instantaneous speed is at all times zero, making it not a moving body, so no on the average speed. The average velocity, on the other hand, can easily be zero. The simplest example is you running in a circle.
Why is acceleration of a body moving uniformaly in a circle directed toward the centre?
The acceleration of a body moving uniformly in a circle is directed towards the center because the velocity of the body is constantly changing direction, even though its speed remains constant. This change in direction of the velocity results in a centripetal acceleration that is required to keep the body moving in a circular path.

Can a body have constant speed and still be accelerating give example?
Yes. The simplest example is an object moving at a constant speed in a circle.
How can a body be accelerating when moving at constant speed?
A body is being accelerated if its speed OR direction are changing.A satellite in a perfectly circular orbit around the earth ... like a TV satellite ... is moving at constant speed. But, technically, since its direction is always changing, to keep it on a circle, it's experiencing constant acceleration.
How many times centripetal force will increase if the angular speed of a body moving with uniform speed moving in a circle is increases?
Centripetal acceleration, and therefore centripetal force, is proportional to the square of the angular velocity. For example, if you increase the angular velocity by a factor of 10, the centripetal force will be increased by a factor of 100.
