Yes they are. Vector quantities has both magnitude and direction, whereas scalar quantities only have magnitude.
Examples of vector quantities:
Displacement (Δd) - 10 m [W] or 36 km [W]
Velocity (v) - 10 m/s [60° N of W] or 36 m/s [60° N of W]
Acceleration - 9.8 m/s2 [↓] - this value is the acceleration dude to gravity (if we ignore air resistance).
Of course. If your velocity is in the north direction for some amount of time,
I'm willing to bet that you'll wind up somewhere north of where you started.
Direction + displacement = velocity
no, velocity=displacement/time
Velocity is the displacement per unit time. V =dx/dt Note velocity and displacement are vectors and have direction.
There is average velocity, and there is instantaneous velocity. I don't think "overall velocity" is a concept generally used in physics; please clarify what you mean.
If you have a Displacement - time graph, the velocity at a certain point equals displacement over time, displacement is a vector quantity thus is affected by direction so when it has a negative value the velocity has a negative value. and if your still thinking about it, check out this thought: "negative velocity is positive velocity in the other direction"
force velocity displacement energy (has to have magnitude and direction)
no, velocity=displacement/time
The simplest answer is the velocity of an object at a given time. It is also possible to determine the acceleration and displacement - but only in the same direction as the velocity. No information on motion in a transverse direction can be determined.
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.

force velocity displacement energy (has to have magnitude and direction)
Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.
You would not have velocity. because you do not have any displacement. You do have Acceleration because your direction is changing.
Displacement and Time, displacement is the distance with a direction ( vector quantity) , and time . Displacement and velocity are directly proportional, while velocity and time are inversely proportional..( The faster, the less time it will take) Velocity = Displacement ____________ Time
Direction and speed which is also velocity.
Vectors are quantities that have both value and direction. Such as displacement and Velocity.
