To know an object's velocity, you need to know its speed and direction.
You can measure speed by calculating how long an object takes to arrive at a new position. So by knowing an object's starting position, ending position, and the time it took to get there, you can calculate its average velocity.
In a more advanced calculation, you could choose starting and ending positions that are extremely close to one another and calculate "instantaneous velocity."
Velocity is known as a "vector value". A vector not only has a length, but a direction. In this case, "length" is the same as "speed", and direction is its change in position.

∙ 15y agoVelocity 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.

What is the objects change in speed called?
That's simply called a change in velocity. On the other hand, the rate of change in velocity - how quickly velocity changes - is called acceleration.
What must you know to determine which of two vehicles traveling at the same velocity has the greater momentum?
You need to know their mass. p=mv momentum=Mass times Velocity
Why is it important to know when there is a tornado coming?
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.
What happens when two objects that have different temperatures touch?
Heat will flow from the object that has the higher temperature, to the one with the lower temperature. This will continue until equilibrium is reached, i.e., both objects have the same temperature.
If a neutral object loses negative charge what will the net force be?
If a neutral object loses negative charge, then all we can say is that the objectwill be positively charged. We don't know anything about force until we knowhow much net positive charge it has, what othercharged object is in theneighborhood, what the size and sign of thatone's charge is, and the distancebetween the two objects.
When do you know an objects velocity?
When you have calculated or measured it.
What is the difference of an objects speed and an objects volocity?
when you know both speed and direction of an objects motion you know the velocity of an object.
When you know the both speed and direction of an objects motion you know the?
Velocity
When you know both the speed and direction of an objects of an objects motion you know the?
I'm pretty sure its the acceleration. If its not that, its the Velocity.
What do you do to find an objects velocity?
You have to know what velocity means to answer this. So the correct answer is S h i t i for get bye
Does gravity always change the velocity of objects?
Only until they hit the ground or the floor.
Does Objects that are falling toward Earth move faster and faster?
Until the object reaches it terminal velocity
How can an objects velocity change?
By changing its direction.
What do you need know to find an objects velocity?
The distance it travels in a caertain amount of time as well as the direction
What is the difference between a objects speed and an objects velocity?
Velocity also includes direction.
What do you need in order to know an objects velocity?
You need to know the distance traveled and the time it took to travel that distance.
What is a objects speed and direction?
Its called VELOCITY.
