Velocity

Velocity is a measure of the rate and direction of an object's movement. It is a vector quantity, which means it has both magnitude (speed) and direction. The formula for calculating velocity is:

Velocity = Displacement / Time

Where:

• Velocity is measured in meters per second (m/s)
• Displacement is the change in position of an object
• Time is the duration of the motion

Velocity can be positive, negative, or zero, depending on the direction of motion. A positive velocity indicates motion in the positive direction, a negative velocity indicates motion in the negative direction, and zero velocity indicates no motion.

Study Guide

Here are some key points to remember about velocity:

1. Velocity is a vector quantity that includes both magnitude and direction.
2. The SI unit for velocity is meters per second (m/s).
3. Velocity can be calculated using the formula:
   Velocity = Displacement / Time
4. Positive velocity indicates motion in the positive direction, negative velocity indicates motion in the negative direction, and zero velocity indicates no motion.
5. Velocity is different from speed, as it includes the direction of motion.

By understanding the concept of velocity and practicing the calculation of velocity using the formula, you can gain a solid grasp of this fundamental concept in physics.
