Acceleration, the change of velocity, occurs. DO NOT EVER CALL IT DECELERATION. That term is for the archetypal caudex ( it's latin, look it up)...
Hence, acceleration includes both the increase AND decrease in the rate of change in velocity...and there you have it.
No. Velocity is the combination of speed and direction. If it is constant, then both the speed and direction are constant. On the other hand, velocity can vary even is speed is constant, since the direction can change.
Yes. The complete description of 'velocity' includes the direction of the motion.
So if the direction changes, then the velocity changes, even if the speed doesn't.
Also, any change of velocity is called "acceleration", even if the speed doesn't change.
Yes. The velocity can change if the speed remains constant and the direction changes.
Yes. Velocity is both speed and direction. A change in either one is acceleration.
This is possible when and object is going the same speed while changing direction. This is because velocity is a vector and speed is a scalar value.
Velocity is dependent on speed AND direction, therefore velocity will change if the direction is changed.
Verily, that statement ringeth with veracity and truth.
It is change directions.
Velocity also includes direction.
Since speed is the magnitude component of the vector quantity of velocity, of course when speed changes velocity also changes. Speed is a one dimensional scalar quantity. Velocity is a three dimensional vector quantity describing both speed and direction of motion.
The speed can be constant but the velocity can't, because the directionof motion ... which is a component of velocity ... is changing. Also the velocity of a moving body changes when its speed changes but remains moving towards the same direction ... :) :]
"Acceleration" means a change in velocity. And "velocity" is a vector - meaning that not only the magnitude, but also the direction is relevant. So, if the direction of the movement changes, the velocity changes by definition, even if the MAGNITUDE of the velocity (also known as "speed") doesn't change.
The accelerator is one: to increase velocity, push the pedal down, to decrease, lift your foot off. The brake is another, apply the brake and velocity will decrease. also the steering wheel affects it. The gas pedal, the brake pedal, and the steering wheel all do.

yes, speed is velocity with a direction
When the object is acted upon by an outside force.
Since speed is the magnitude component of the vector quantity of velocity, of course when speed changes velocity also changes. Speed is a one dimensional scalar quantity. Velocity is a three dimensional vector quantity describing both speed and direction of motion.

Speed.If you also know what direction it changes, then you have velocity.
Yes; if the direction changes (for instance, if an object moves in a circle), even if its speed doesn't change, its velocity changes. This is because the term "velocity" also includes the direction.
"Acceleration" means a change in velocity. And "velocity" is a vector - meaning that not only the magnitude, but also the direction is relevant.

Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
Speed is magnitude of velocity, also velocity possess direction.
