In general ultrasonic velocity is considered as a constant value relative to the material.
The velocity of a projectile is considered to be constant when there is no change in speed and direction. This usually occurs in the absence of any external forces, such as air resistance or gravity, that could affect the projectile's motion.
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
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.
If your velocity is constant, then your acceleration is zero.
constant slope. really anything will work as long as it stays the same. so if your line is straight then you have a constant velocity. :)
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
An object in uniform circular motion undergoes constant acceleration but moves at constant "speed".Constant "velocity" means no acceleration.
Yes, speed is the scalar of velocity.
Constant velocity means constant speed in a straight line.
No, an object cannot accelerate if its velocity is constant. Acceleration is defined as the rate of change of velocity, so if the velocity of an object is constant, its acceleration is zero.
An object traveling at constant velocity cannot have acceleration because acceleration is the rate of change of velocity over time. If the velocity of an object is constant, there is no change in velocity and therefore no acceleration.
