Because he did that so she had to do it and 1=1+2.
velocity continuously because velocity has both magnitude and direction. In a circular path, the direction of the object's velocity is constantly changing as it moves around the circle, even though its speed (magnitude of velocity) may remain constant.
In uniform circular motion, the speed of the object remains constant as it moves around the circle. However, the velocity of the object changes because the direction of the velocity vector is constantly changing. The centripetal acceleration remains constant in magnitude and always points towards the center of the circle.
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
The velocity of the object is constantly changing in direction as it moves around the circle. This change in direction indicates a change in velocity, even if the speed remains constant.
Acceleration is the rate of change of velocity. Even if an object's speed is constant, acceleration can still occur if the direction of the object's motion changes. For example, when an object moves in a circle at a constant speed, it is undergoing acceleration towards the center of the circle due to the change in its direction of motion.
Yes, for example, if it moves in a circle.
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
The velocity increases at a constant rate.

An object that moves with constant position will have constant velocity or acceleration. This is said to be moving in positive direction and maintains the position.
In uniform circular motion, the speed of the object remains constant as it moves around the circle. However, the velocity of the object changes because the direction of the velocity vector is constantly changing. The centripetal acceleration remains constant in magnitude and always points towards the center of the circle.

Yes, it can. Perhaps the simplest example is when an object moves at constant speed, in a circle. In this case, the speed doesn't change; the velocity does.
The velocity of the object is constantly changing in direction as it moves around the circle. This change in direction indicates a change in velocity, even if the speed remains constant.
Acceleration is the rate of change of velocity. Even if an object's speed is constant, acceleration can still occur if the direction of the object's motion changes. For example, when an object moves in a circle at a constant speed, it is undergoing acceleration towards the center of the circle due to the change in its direction of motion.
Constant velocity means that the object's speed is constant, and it moves in a straight line, i.e. the direction of its motion is also constant. When an object moves in a manner consistent with this description, probability dictates that sooner or later, it bumps into something.
It velocity is constantly increasing, v=vo + at.
