. . . velocity, because one of the components of velocity
is the direction of the speed.
Velocity
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
The Doppler effect
1.5 km is a distance, not a speed.
Acceleration means any change in either speed or direction of motion.If speed remains constant, there may still be acceleration present if thedirection of the motion is changing.If the rate at which speed and/or direction are changing remains constant,then the acceleration is constant
If the path is perfectly circular, yes, the speed is constant. This should not be confused with the velocity, because while speed is constant, its direction is not; therefore velocity is always changing.
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
Not necessarily.Speed is a scalar measurement that only measures magnitude.Velocity, on the other hand, is a vector measurement and adds the important distinction of a direction.A car rounding a curve may be going the same speed, but its velocity is constantly changing throughout the curve because its direction keeps changing.
An accelerating object is one that is changing in either speed or direction. Thus any object that is turning is accelerating while maintaining a constant speed.
An object that moves with constant position will have constant velocity or acceleration. This is said to be moving in positive direction and maintains the position.
Constant velocity means that the object's speed is constant, and it moves in a straight line, i.e. the direction of its motion is also constant. When an object moves in a manner consistent with this description, probability dictates that sooner or later, it bumps into something.
A ball rolled across a horizontal table moves at constant velocity.why?
moves
is moves with a constant velocity in the positive direction......
The velocity increases at a constant rate.
A horse's shadow.Horses shadow.
It means that the object moves in a straight line at a constant speed.
