## What is a velocity vector diagram?

Vector diagrams are diagrams that depict the direction and relative magnitude of a vector quantity by a vector arrow. Vector diagrams can be used to describe the velocity of a moving object during its motion. For example, a vector diagram could be used to represent the motion of a car moving down the road.

## What is a momentum vector diagram?

To construct a momentum vector diagram (MVD), we use the idea of motion diagrams together with the graphing vectors to create the momentum vector. In Fig. 3 a 2-kg object is moving to the right at a speed of 3 m/s. The momentum vector can be found by multiplying the velocity and mass of the object.

## How do you find the momentum vector?

Momentum is a derived quantity, calculated by multiplying the mass, m (a scalar quantity), times velocity, v (a vector quantity). This means that the momentum has a direction and that direction is always the same direction as the velocity of an object’s motion. The variable used to represent momentum is p.

## How do you find velocity vector?

Start with this equation: vf = vo + a x t. Convert the original velocity into vector component notation. Use the equation vx = v cos theta to find the x coordinate of the original velocity vector: 44.0 x cos 35 degrees = 36.0.

## What are velocity diagrams used for?

Hint: Velocity diagrams are the diagrams that use a vector arrow to indicate the direction and the relative magnitude of a vector quantity. To define the velocity of a moving object during the phase, vector diagrams may be used.

## How do you find momentum after a collision?

Multiply the second object’s mass by its velocity. For example, if it weighs1,000 and has a velocity of -30 meters per second, then its momentum will be 30,000 kg meters per second. Add the two velocities together to determine which way the objects will move after collision.
