Velocity

Velocity is a measure of the speed 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 the speed and direction of the object
• Displacement is the change in position of the object
• Time is the duration over which the displacement occurs

Factors Affecting Velocity

Several factors can affect an object's velocity:

1. Force: The application of force can change the velocity of an object.
2. Direction of Motion: Changing the direction of motion will change the velocity even if the speed remains constant.
3. Friction: Friction with the surroundings can reduce the velocity of an object.

Units of Measurement

Velocity is typically measured in units such as meters per second (m/s) or kilometers per hour (km/h).

Study Guide

Here are some key points to remember about velocity:

1. Velocity is a vector quantity, meaning it has both magnitude and direction.
2. The formula for velocity is velocity = displacement / time.
3. Factors such as force, direction of motion, and friction can affect an object's velocity.
4. Velocity is typically measured in units such as meters per second (m/s) or kilometers per hour (km/h).
