#### Overview

Upon completion of this lesson, student must be able to:

• Define terms related to motion of a body.
• Reproduce the equations related to motion in a straight line.
• Differenciate scalars and vectors.
• Solve numerical related to motion.

#### Velocity

The velocity of the body is the distance travelled by it in unit time to a certain direction. If a moving body covers the equal distance in equal interval of time , then the body is said to have uniform velocity. If a moving body covers the different distance in unit time then the body is said to have variable velocity. This note provides information about velocity, definition, example and help for numerical problem. Learn More

#### Acceleration and Retardation

Acceleration is defined as the change in velocity per unit time. The negative acceleration is called retardation or deceleration. This note provides us with an information about acceleration and retardation.
