Now that you are familiar with how an object's velocity changes over time in linear motion, we now shift our focus to angular motion, where similar principles apply to rotational systems. Use this resource to gain insight into the rotational behaviour of objects, and better understand the dynamics of systems...

Sometimes an object speeds up or slows down at a steady rate. For example, a car joining a freeway may increase its speed by the same amount every second, or a dropped object (ignoring air resistance) gains about \(\mathbf{9.8}\,\textbf{m/s}\) of speed each second as it falls. In these situations, the...

Linear motion is how an object moves in a straight line. To describe these motions, we need to know some technical terms like displacement, distance, velocity, speed and acceleration, and how to represent how they change over time. Use this resource to learn about the terms and their relationships to...

In many cases, acceleration changes over time. You see this when a car that has been stopped at a traffic light speeds up to \(\mathbf{60}\,\textbf{km/h}\) after the light changes to green. Acceleration also varies throughout a rollercoaster ride. Both of these scenarios demonstrate non-constant (or non-uniform) acceleration. Use this resource...
