Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.
For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.
No. A body can have constant speed but changing direction thus changing velocity. For example, an orbiting body may have a constant speed s=wr, but its direction is constantly changing as it follows the curve of its orbit.
Yes, it is constant at zero. I.e. there is no acceleration so velocity must be constant
Answer: yes velocity because velocity is traveling in the same direction at the same speed so yes it is traveling in a straight line
A car moving with a constant speed is moving with a constant velocity if and only if it is travelling along a straight line.
That is possible only if another force acts in the opposite direction, and the total force on the object is zero. This is often the case if there is friction.
No. If there is a net force (if the sum of all the forces is not equal to zero), then there will be an acceleration, and the velocity will NOT be constant.
An object moving at a constant speed in a straight line needs a force to act on it to keep it in uniform motion when it is affected by other forces such as wind or frictions.
yes, windspeed and sometimes friction.
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
A car moving at constant speed in a straight line is also moving at constant velocity.
there is no acceleration if the body is moving with constant velocity
No. You can't tell the difference, for one reason: There IS no difference.
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
... continue to do that, until a force is exerted on it.

a "body" "moving body" an "object" is moving with constant velocity. [OR] a "body" is moving with constant velocity.
A car moving at constant speed in a straight line is also moving at constant velocity.
No, because acceleration is the rate of change of velocity.
there is no acceleration if the body is moving with constant velocity
No. You can't tell the difference, for one reason: There IS no difference.
No,because if the car is moving at a constant velocity that means the acceleration is zero. So the net force is zero and there may be some forces acting on it. Only gravity, downward.

A=dv/dt so hell Nah if that dv/dt bs is 0. Duh. And what's with the second constant velocity bs too? Proofread man. You're better than that.
since accelaration is the change in velocity of an object per unit time......if velocity is zero then there is no acceleration.its nt possible
