Initial velocity

Definition

Initial velocity is the velocity of an object at the starting point of a time interval. It is often denoted by $v_0$ or $u$ in equations.

5 Must Know Facts For Your Next Test

1. Initial velocity can be found using integration if acceleration as a function of time is given.
2. In differential equations, initial conditions typically include the initial velocity.
3. It plays a crucial role in solving problems involving motion described by second-order differential equations.
4. The units for initial velocity are meters per second (m/s) in the SI system.
5. When acceleration is constant, initial velocity is used along with acceleration to determine the position and final velocity at any time.
