Assuming you mean CV joints in a car, they will not need replacement unless they are becoming defective.
Turning in a sharp circle, both forwards and backwards, not at high speed - if you hear a click click click, then the CV joints are in trouble.
This is not an urgent (i.e. NOW) problem, but is worth doing before the next scheduled service.
It doesn't have universal joints. The axle shafts have constant velocity (CV) joints.It doesn't have universal joints. The axle shafts have constant velocity (CV) joints.
Normally there are constant velocity joints not u-joints.
it is the velocity of two rubbed pin joints in kinematic pairs.
If your vehicle has grease joints, every oil change.
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.
A change in velocity constitutes a change in direction because velocity includes direction.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Change in velocity = Velocity at the end of the period minus velocity at the start of the period.
The generic term for change in velocity is acceleration. It may be positive or negative (often called deceleration in non-scientific use) or may be a change in vector (direction of travel). This is because velocity is speed (distance covered per time unit) and direction of travel combined.
Yes. Acceleration is a change in velocity; velocity is a change in speed and or direction. I am not sure what motion means in a technical sense (velocity?).
Angular acceleration is the trate of change of angular velocity, often represented by the letter alpha.
