1. The transformation formula for v=s/t can be expressed in two common forms: s=v*t and t=s/v.2. In uniform rectilinear motion, the speed of an object remains constant, indicating that speed is independent of both distance and time.3. In uniform rectilinear motion, the distance traveled by an object is directly proportional to the time taken.4. Objects traveling the same distance will experience varying time intervals, with higher speeds resulting in shorter durations.5. The conversions among speed, distance, and time include: 1) Distance equals speed multiplied by time: Distance = Speed * Time. 2) Speed equals distance divided by time: Speed = Distance / Time. 3) Time equals distance divided by speed: Time = Distance / Speed.6. Velocity is a vector that describes the rate of change of position of a moving point at a specific instant, including both speed and direction.7. In the simplest case of uniform rectilinear motion, the magnitude of velocity is equal to the distance covered per unit of time.8. Common units for speed include centimeters per second, meters per second, and others.
