Скачать или смотреть Speed velocity and acceleration velocity series

Speed and velocity are concepts in physics that describe the motion of an object, but they have distinct definitions:

1. **Speed**:
**Definition**: Speed is a scalar quantity that measures the rate at which an object covers distance.
**Formula**: \( \text{Speed} = \frac{\text{Distance}}{\text{Time}} \)
**Units**: Common units include meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph).
**Characteristics**: Speed does not have a direction; it only tells how fast an object is moving.

2. **Velocity**:
**Definition**: Velocity is a vector quantity that measures the rate at which an object changes its position. It includes both speed and direction.
**Formula**: \( \text{Velocity} = \frac{\text{Displacement}}{\text{Time}} \)
**Units**: The units of velocity are the same as speed (e.g., m/s, km/h, mph), but it also includes direction (e.g., 50 km/h north).
**Characteristics**: Velocity specifies how fast and in which direction an object is moving.
