When stating the velocity of an object, you need to know both the speed (how fast the object is moving) and the direction in which it is moving. Velocity is a vector quantity that combines magnitude (speed) and direction, so both pieces of information are necessary to describe it accurately.
What else can I help you with?
Anya knows the velocity of an object. What else does she need to know in order to find the objects momentum?
The mass of the object.
When you know both speed and direction an object in motion you know the?
When you know both speed and direction of an object in motion, you know the velocity of the object. Velocity is a vector quantity that describes how fast an object is moving and in what direction.
When you know both speed and direction of an object's motion you know the?
When you know both the speed and direction of an object's motion, you know its velocity. Velocity describes both how fast an object is moving (speed) and in what direction it is moving.
How two things do you need to know to describe the velocity of an object?
To describe the velocity of an object, you need to know both the speed (magnitude of the velocity) and the direction of the object's motion. Velocity is a vector quantity that includes both of these aspects.
Which quantities do you need to know in order to determine the change in an objects momentum?
To determine the change in an object's momentum, you need to know the initial momentum of the object (mass x initial velocity) and the final momentum of the object (mass x final velocity). The change in momentum is equal to the final momentum minus the initial momentum.
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.
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
Anya knows the velocity of an object. What else does she need to know in order to find the objects momentum?
The mass of the object.
How do you know something is moving faster than some other object?
Calculate the average velocity for the objects.
If an object falls of a shelf how do you know a force as acted on it?
You know a force has acted on the object because the objects velocity has changed as the result of a force, f= mdv/dt.
What object has the least inertia?
The magnitude of inertia of an object is we consider the velocity and mass.The object that has least inertia is object that has small mass and velocity.This because the small mass and velocity the easiest it to stop or stop it.As we know that inertia is the tendency of object to remain its state in rest or in uniform velocity in straight line.Small massan velocity of object the small tendency of object to remain it state in rest or in uniform velocity in straight line.
When you know both speed and direction an object in motion you know the?
When you know both speed and direction of an object in motion, you know the velocity of the object. Velocity is a vector quantity that describes how fast an object is moving and in what direction.
When you know the speed and the direction of an object's motion you know what?
The magnitude and direction of the object's velocity vector.
When you know both speed and direction of an object's motion you know the?
When you know both the speed and direction of an object's motion, you know its velocity. Velocity describes both how fast an object is moving (speed) and in what direction it is moving.
You do not know an objects velocity until you know what?
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.
