Speed, Acceleration, and Position
Velocity is equal to distance divided by time.
If you know the speed and direction of the object's motion, then you know its velocity.
We distinguish between speed and velocity because if you add the speedsof objects, their directions are important. For example, the velocity of an airplane with ...
velocity of the object
object's velocity
Velocity is speed and direction. It is important to know the velocity and not just the speed, because with both speed and direction you can figure out where a tornado is going and when it should get there.
No. For you to know acceleration you need the rate of change of speed and the direction.
The magnitude and direction of the object's velocity vector.
No. For you to know the distance you need to know the time the object has been travelling and a function describing the speed of the object for the time it has been travelling. A direction is not required. correct but you missed direction can affect speed as climbing altitude would get slowed by gravity
you now this because speed is how fast an object is ''moving'' and motion is when an object is ''moving''
velocity
