What else can I help you with?
Can object at constant speed can maintain constant velocity?
Yes, an object moving at a constant speed can maintain a constant velocity if it is moving in a straight line without changing its direction. Velocity is a vector quantity that includes both speed and direction, so as long as the direction does not change, the object's velocity will remain constant.
Is the velocity of an object in UCM constant?
No, the velocity of an object in uniform circular motion (UCM) is not constant. While the speed of the object remains constant, the velocity changes continuously in direction due to the centripetal acceleration required to keep the object moving in a circle.
Suppose the force of friction on a sliding object is 10N. what is the force needed to maintain a constant velocity is?
To maintain a constant velocity, the force needed to overcome the frictional force must be equal in magnitude but in the opposite direction. Therefore, a force of 10N is needed to maintain the constant velocity of the sliding object.
Can an object have a constant spped and velocity at the same time?
Velocity is a vector quantity. That means it has direction and magnitude. Speed is a scalar quantity, it only has magnitude. It is possible to have constant speed and constant velocity but it is also possible to have constant speed but changing velocity if the object is changing direction.
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
Can an object maintain uniform velocity when its acceleration is non zero?
No, an object cannot maintain uniform velocity when its acceleration is non zero. If an object is accelerating, its velocity will be changing over time, so it cannot maintain a constant velocity. Uniform velocity means the speed and direction of the object remains constant.
Can object at constant speed can maintain constant velocity?
Yes, an object moving at a constant speed can maintain a constant velocity if it is moving in a straight line without changing its direction. Velocity is a vector quantity that includes both speed and direction, so as long as the direction does not change, the object's velocity will remain constant.

Why is no force required to move an object with a constant velocity?
Newton 2nd Law is the answer
Why achanging velocity cannot maintaining constant speed?
Velocity is a vector quantity that includes both speed and direction. If the velocity is changing, it means either the speed, direction, or both are changing. Therefore, if the velocity is changing, the object cannot maintain a constant speed.
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
The property of a body that causes it to remain at rest or to maintain its constant velocity is called?
The property is called inertia. Inertia is the tendency of an object to resist changes in its motion. It can keep an object at rest or maintain its constant velocity unless acted upon by an external force.
Why an object will move if its velocity is constant?
If an object's velocity is constant, it will continue to move at the same speed and in the same direction due to Newton's first law of motion. Unless an external force is applied, the object will maintain its state of motion.
Can an object traveling at constant velocity have acceleration?
No, if an object is traveling at a constant velocity, it means that its speed and direction are not changing. Acceleration is the rate at which velocity changes over time, so an object with constant velocity by definition cannot have acceleration.
Can an object have constant velocity and but variable speed?
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
