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 means that the object moves in a straight line at a constant speed.
It velocity is constantly increasing, v=vo + at.
It moves with a constant acceleration downwards. This means that its velocity is increasing at a constant rate.
An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.
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 increases at a constant rate.
It means that the object moves in a straight line at a constant speed.
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.
If the net force on an object is zero, then velocity of the object is constant ... it moves in a straight line at a constant speed.
it is in equilibrium.
It velocity is constantly increasing, v=vo + at.
It moves with a constant acceleration downwards. This means that its velocity is increasing at a constant rate.
Both are definitely zero
The acceleration of an object with constant velocity is zero. It's force will be Mv^2 where M is it's mass and v is it's velocity.
An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.
it moves with uniform velocity ... constant speed in a straight line
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.
