Yes - just like any velocity, average velocity is a vector and has a direction associated with it. Speed, on the other hand is only an intensive property which has no specific direction associated with it. You could consider speed to be the magnitude of the velocity vector.
That is its definition, to put it simply. Velocity is a vector quantity, meaning it has a direction, and thus when you add, subtract, multiply or divide velocities, you must take into account whether they are positive or negative.
Yes. Well, actually, in informal language "speed" and "velocity" are often used interchangeably. But in physics, the words are used with different meanings - "speed" being just a number (and a measurement, of course), whereas "velocity" includes information about the direction as well.
no because whether the direction is north or south the velocity is still the same
(if there is no difference in their paths)
Yes, velocity has magnitude and direction. Speed, on the other hand, only has magnitude.
Of course. 30 mph for an hour heading north from your house, and 30 mph heading southwest from your house, will take you to two completely different places.
"Speed" is the term used in physics when you don't care about the direction. If you care about the direction, that is, you want to work with a vector, then the term "velocity" is used.
yea, it is a vector.
Velocity.
As velocity is changing that means acceleration/deceleration is taking place. Hence, Force will not be equal to zero. However, the direction of force will depend on the direction of velocity of body. So, it's not possible to predict whether the force will be positive or negative. The net force can not be found as the dimensions of body like mass and change in velocity are not given in the question.
-- the magnitude and direction of the force acting on an object -- the mass of the object being forcefully acted upon
Velocity is a vector; having direction. So, when changing direction constatly to have velocity a tangent can be drawn to the constantly changing path of the object having velocity.
Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction. Speed without reference to a direction is a scalar, a magnitude without direction.
Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
no,because speed is scalar which has magnitude only meanwhile velocity is vector which has magnitude and direction
Speed in a given direction is velocity.
Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.
Velocity does depend on distance. Velocity = Distance/Time
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.
That's going to depend on where the bus leaves from, or ... what is equivalent ... what direction it has to head in order to get to Alpharetta. You can't talk about a velocity without a direction.
Speed in a given direction is called velocity.
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.
By definition p=mv: momentum = mass * velocity (speed if you don't care about direction)
you know that i am your father and u are my son in the same way average velocity is your mother and velocity is your sister so go home u are drunk
A change in velocity constitutes a change in direction because velocity includes direction.
