Direction.
Velocity tells us the speed at which an object is moving and the direction in which it is moving.
Velocity tells us the speed of an object's motion as well as its direction of movement.
The word speed is distance per unit of time. It is frequently used as a substitute for velocity, and it is in more common usage. But there is a difference between speed and velocity. Velocity has a direction vector associated with it. It's speed + direction. That's usually not a big deal when talking about "regular" stuff, but don't tell a physics teacher that.
Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
You check out the speed and direction, and times them together, and it will tell you the velocity of the object.
Their 'sizes' are. But if you want it to be a velocity, thenyou also have to tell the direction of the speed.
If you call it "velocity" then you have to tell what direction it points.If you only tell how fast it is but you don't tell the direction, then it's "speed", not velocity.
The speed and direction of an object is its velocity.
Velocity tells us the speed at which an object is moving and the direction in which it is moving.
88 mph is 88 miles per hour, since that doesn't tell you what direction it is going it is speed. Velocity is speed and direction.
Speed and direction combined produce velocity, which is a vectory notation.
Velocity tells us the speed of an object's motion as well as its direction of movement.
Add to it some kind of label to tell the directionof the speed.
How the speed of something changes over time.
The word speed is distance per unit of time. It is frequently used as a substitute for velocity, and it is in more common usage. But there is a difference between speed and velocity. Velocity has a direction vector associated with it. It's speed + direction. That's usually not a big deal when talking about "regular" stuff, but don't tell a physics teacher that.
Speed is a scalar quantity and has only magnitude and not direction. Hence, speed cannot tell us what direction an object is moving. However, velocity which is the vector equivalent of speed, can tell us the direction.
