Velocity is a vector (has a size and a direction) but speed is a scalar (just a number).
The velocity is therefore given by the speed and the direction the speed is going. If you change the direction but continue at the same rate the velocity changes but the speed doesn't
No, it isn't possible. Velocity specifies both speed and direction; if velocity doesn't change, that means that neither the speed nor the direction change.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
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.
The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.
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.
No, it isn't possible. Velocity specifies both speed and direction; if velocity doesn't change, that means that neither the speed nor the direction change.
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
Not necessarily. Constant velocity also means no change in direction.
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
constant speed means no acceleration and thus no change in velocity
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 motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
a "body" "moving body" an "object" is moving with constant velocity. [OR] a "body" is moving with constant velocity.
The velocity does not change direction or magnitude. The object 1) may not be moving, or it 2) may be moving at a constant velocity. In the case of the latter, that means it's moving in the same direction and at a constant speed.
