Intro to vectors & scalars | One-dimensional motion | Physics | Khan Academy

The text discusses the concept of time and its direction, and explains that when an object moves over a distance of 5 meters, the change in time can be measured as 2 seconds. This indicates that time only moves in a positive direction and can be treated as a scalar or vector quantity in simple physics. The speed of the object is calculated to be 2.5 meters per second, which is a scalar quantity when no direction is given. Speed measures how fast an object moves without considering its direction, while velocity includes both speed and direction. To determine an object's speed, you need to provide directional information. Without direction, speed refers to the object's velocity, which combines speed and direction.
