In the field of physics, the term velocity refers to the rate at which an object changes its position, taking into account both the speed and direction. While average velocity is relatively ...

Instantaneous speed is a crucial concept in physics, helping us understand how fast an object is moving at a specific point in time. Unlike average speed, which considers the total distance traveled ...

An average speed for a journey can be found from a distance-time graph by working out the gradient of the line between the two points of interest. This is like using a car's milometer and clock to ...

When a relationship between two variables is defined by a curve it means that the gradient, or rate of change, is always varying. An average speed for a journey can be found from a distance-time graph ...
