when you know both speed and direction of an objects motion you know the velocity of an object.

velocity describes the speed and the direction of an object's motion.

If you know the speed and direction of the object's motion, then you know its velocity.

Velocity is a vector. It is a combination of speed and direction. In other words, yes, if you know an object's velocity, you know both its speed and its direction of motion.

you now this because speed is how fast an object is ''moving'' and motion is when an object is ''moving''

When you know the speed and the direction in which the object is moving, that term is called Velocity, speed + direction. the SI unit for velocity is m\s (metre per second)

Velocity means speed and direction. So if you know the speed, all you need to add is the direction of motion and you will have the velocity.

to find the speed and direction of an objects velocity

Yes. Velocity is a vector quantity that needs a magnitude (speed is the corresponding scalar to velocity) and a direction.

We all know that the rate of motion is referred to as the speed or sometimes average speed.. but if we add here the direction of motion than we have our velocity. Velocity is the speed of an object moving in a definite direction. The velocity of an object can be uniform or variable (non-uniform). It can be changed by changing the objects speed, direction of motion or both. When an object is moving along a straight line at a variable speed , we can express the magnitude ( amount of physics quantity in numerical way) of its rate of motion in terms of velocity. It is calculated in the same way as we calculate speed . AVERAGE VELOCITY = initial velocity + final velocity / 2... Mathematically = Vav = u + v/ 2 .. thanks.. JAI HIND

We don't know what the forces were or in what direction, and we don't know anything about the object. So we have no idea what its motion looks like when the forces end. But we do know that whatever speed it has and whatever direction it's moving at the instant the forces stop, it'll continue in the same direction at the same speed from then on.

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

the direction and speed of the object are the two things u need 2 know

Speed.If you also know what direction it changes, then you have velocity.

The direction in which it's moving. This is a very important concept, and a great question.

Motion is the act of moving. Direction is the act of motion in a said locations.

By definition, it would have the same speed and direction as the compared object. This can be evidenced by the two objects having an unchanging spatial relationship: i.e. the objects remain the same direction and distance from each other.

Speed and direction combined produce velocity, which is a vectory notation.

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.

False. You will know nothing at all about any force acting perpendicular to the direction of motion.
