Dynamics: Relationship of Two Particles

Relationship of Two Particles

Two particles can be related to each other with a relative position, velocity, or acceleration at an instant in time. To calculate the relative position, velocity, or acceleration the following equations would be used.

Relative Position Equation (1)

Relative Velocity Equation (2)

Relative Acceleration Equation (3)

Relative position, velocity, and acceleration relationships

In many cases these types of problems will have motion in multiple directions. To solve these types of problems refer to the example below.
