No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
No. Acceleration is the change in velocity(speed) over a period time.=====================================Another contributor bristled:Sorry. Velocity and speed are not two different words for the same thing.Velocity means speed and direction, and acceleration means any change in velocity.If the speed is constant but the direction is changing ... like turning a corner or drivingon a circular track ... then velocity is changing, and there is acceleration.
If the direction of motion is constant then the velocity is the same as the speed in that direction. If the direction is not constant, the information given is nowhere near sufficient to calculate the velocity.
You are driving your car with cruise control but you steer around a bend in the highway. The cruise control keeps your speed constant, but by steering you change your direction and thus your velocity is not constant.
Uniform velocity means that an object is moving in a straight line at a constant speed, while constant velocity adds the additional condition of moving with a constant speed and direction. In other words, constant velocity implies both uniform speed and no change in direction.
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
Yes, speed is the scalar of velocity.
Constant velocity means that an object is moving at a steady speed in a straight line, without changing its velocity. Variable velocity means that an object's speed or direction is changing over time, resulting in a non-constant velocity.
No. Velocity includes a direction vector, which speed does not have.
Yes, when an object is moving at a constant velocity, it means it is moving with a consistent speed in a straight line. Velocity includes both speed and direction, so if the direction remains constant, the speed must also remain constant.
Speed is the magnitude of velocity, so if the speed of an object is constant, it means that the object is moving at a consistent rate. Velocity, on the other hand, is a vector quantity that includes both speed and direction, so if the direction of an object changes, its velocity changes even if the speed remains constant.
No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.
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, if the instantaneous velocity of an object remains constant, then its instantaneous speed cannot change. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and direction are constant.
No, a particle with constant speed cannot be accelerating, as acceleration is the rate of change of velocity. If a particle has constant velocity, it is not accelerating because its velocity is not changing in magnitude or direction.
Velocity is a vector quantity that includes both speed and direction. If the velocity is changing, it means either the speed, direction, or both are changing. Therefore, if the velocity is changing, the object cannot maintain a constant speed.
