Are you accelerating if you are traveling in a constant direction with constant speed and explain?
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
Does velocity of an object remain constant in uniform circular motion?
Velocity is a vector with magnitude (speed) and direction. Since the linear velocity changes direction the speed is constant but the velocity is NOT constant.
Can you be accelerating if you are traveling at constant speed?
Velocity is speed in a certain direction. You can keep speed the same, and if you change direction then you have changed velocity.
Does the velocity of a car traveling at constant speed around a pole change?
yes, It accelerates (and does so at a constant rate - if the rate of turn is constant) in the direction of the turn. The speed is constant, but the direction the car is going changes at each instant in time because it is turning. And because it is changing direction, that means its velocity is changing (because velocity is speed plus a direction vector).Read more: What_happpens_to_a_car_moving_at_a_constant_speed_as_it_turns_a_corner
When you run around a track at 5 km h your velocity is constant?
No. Your speed is constant but your velocity is not. Velocity is a vector and as you run around a track, the direction of your motion changes and so the velocity changes - not in magnitude but in direction.

Velocity is a vector with magnitude (speed) and direction. Since the linear velocity changes direction the speed is constant but the velocity is NOT constant.
Why is an object traveling in a circular motion?
acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.
Can you be accelerating if you are traveling at constant speed?
Velocity is speed in a certain direction. You can keep speed the same, and if you change direction then you have changed velocity.
Does constant speed give you constant velocity?
No. The speed can be consant but direction can change and thus the velocity changes.

Why is it an object can accelerate while travelling at constant speed but not at constant velocity?
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.
Why the speed of an object is constant while the velocity is not?
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.
' uniform motion in a circle in which speed is constant but velocity is changing'?
This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.
Can something keep a constant velocity in a curve?
No. It can keep a constant SPEED in a curve. But if the direction changes, then that's a change of velocity, and the direction in a curve is constantly changing.
Why is an object traveling at a constant speed but turning left said to be accelerating?
Acceleration is not a change in speed, but a change in velocity. Velocity is, unlike speed, a vector, and so as the direction of velocity changes there must be an acceleration to cause that change.
