To calculate the instantaneous speed of an object mathematically, we use calculus, specifically the concept of derivative. Given a function s (t) that represents an object’s position (s) with respect ...

Example The velocity of a sledge as it slides down a hill is shown in the graph. Find the acceleration of the sledge when t = 6s.

Introduction 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 ...
