This video explains how the direction and gradient of a line on a velocity-time graph can tell us whether an object is accelerating, moving at a constant velocity or decelerating. Velocity time graphs ...

Learn how to analyze motion graphs in physics, including position-time and velocity-time graphs. This video explains slopes, areas, and motion behavior to help you clearly interpret real physics ...

Shini Somara introduces us to the ideas of motion in a straight line. In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight ...

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 ...

One of the most basic things students do in a physics lab is to collect data and use that to build a model. Most of these models come in the form of a mathematical function. But here is the problem.
