That depends: based on what information? One calculation you might do is to add the original velocity with the velocity change (vector addition). However, normally you would proceed the other way: you would have to MEASURE the original velocity and the final velocity, and THEN calculate the difference in velocity.f
What else can I help you with?
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.
What 2 ways causes an object's velocity to change?
If an object's speed changes, or it heads off in a new direction, its velocity has changed. Because of friction and gravity 1. acceleration 2. deceleration 3. change of direction
What the role of velocity in physics?
Velocity is a vector quantity that describes how fast and in which direction an object is moving. It is essential in physics as it helps us understand the motion of objects, calculate displacement, and determine acceleration based on changes in velocity over time. Velocity combines speed (magnitude of motion) with direction, providing a more detailed description of an object's movement.
What causes a wave to bend and travel in a new direction when it moves from one medium to another?
When a wave moves from one medium to another, its speed changes due to the different properties of the new medium. This change in speed causes the wave to bend, a phenomenon known as refraction. The amount of bending depends on the change in speed and the angle at which the wave enters the new medium.
What describes the refraction of a wave?
Refraction of a wave occurs when it changes direction as it passes from one medium to another with a different speed, due to a change in its velocity. This change in velocity causes the wave to bend at the boundary between the two mediums. The amount of bending depends on the change in speed and the angle at which the wave enters the new medium.
When we subtract a velocity vector from another velocity vector the result is?
The result of subtracting one velocity vector from another velocity vector is a new velocity vector. This new vector represents the difference in speed and direction between the two original velocity vectors.
Is speed and velocity the same thing?
Scientifically, Both are are distance over time. Speed is a scalar, however, which means there is no direction involved. Velocity on the other hand is known as vector, meaning direction is included. So like when an object is spinning round and around, its speed can be constant, but, because the direction is changing, the velocity does not remain constant. In common speech though the two are interchangeable
Why are your velocity changes when you ride a ferris wheel even if the wheel turns at a constant speed?
A ferris wheel turning at a constant speed has no change in speed. But velocity is speed with a direction vector attached to it. Speed with a direction component is velocity. In this case, the distance per unit of time (speed) that something is traveling is constant, but the direction it is traveling is constantly changing because that something is moving in an arc (or circle). It's a ferris wheel, and anything on it has its velocity changing. Velocity is changing every second because the direction it is moving is changing. Any change in the velocity of an object will require that the object be accelerated. Even if its speed is constant, it will experience acceleration to change "just" the direction it is traveling. It's the same with an object in orbit. The object will be cruising along at a constant speed, but its velocity will be constantly changing. This is because the direction the object is moving is changing because it is being accelerated constantly to get it to move in an arc. The object was put in orbit, and it was accelerated into that orbit. Now, the object is being acted on constantly by gravity. The gravity is pulling the object back to earth, but if we look at where it is going at any instant of time, it is moving on a tangent to its path of travel. It moves a tiny bit on that tangent, and gravity pulls it "in" just a tiny bit, and that makes it path an arc. A little on the tangent, and a little "in" toward earth. A little more on the "new" tangent path, and a little "in" toward earth. A little more along the new tangent path, and a little more in toward earth. A smooth arc - a circle. The object in orbit is constantly being accelerated toward earth, and this acceleration constantly changes its velocity (but not its speed), and it moves in that circular orbit.
How do you calculate the new velocity so that momentum remains same?
apply conservation of momentum theory- m1v1=m2v2 where m1 is the initial mass, m2 is the final mass, v1 is the initial velocity and v2 is the final velocity.
Velocity of a wave increases and the wavelength stays the same. What will the result be when this happens?
Assuming an electromechanical wave not much. The speed of the wave depends on the medium that the wave is passing through. In a vacuum it is the speed of light, through something else a lesser speed. The wavelength stays the same and the frequency stays the same.
What is the velocity of a ship that traveled from London to New York in 6 days?
First you need to know the distance between London and New York, then divide the distance by the number of days (6) to calculate distance per day, then divide by 24 (hours per day) to calculate distance per hour (velocity per hour).
What are the conditions for an object to stay at restto keep moving at constant velocity?
"Constant velocity" means neither the speed nor the direction of the object's motion is changing. "Rest" is just one kind of constant velocity ... the kind with zero speed. The condition for an object's velocity to remain constant is: Either there are no forces acting on the object, or else all of the forces acting on it add up to zero. If there is any NET force acting on the object, then its velocity will change ... it will either speed up, slow down, or curve in a new direction.
