Acids and bases are vital chemical compounds with significant roles in both science and daily life. Acids, with their sour taste and reactivity, are found in citrus fruits and vinegar, while bases, known for their bitter taste and slipperiness, appear in cleaning products and baking soda. When acids and bases...

Whenever a force is distributed across a surface, it acts through a single point called the centroid. Finding the centroid tells us where to apply the equivalent resultant force, which we need to analyse structural behaviour. Use this resource to learn how to locate the centroid for simple and composite...

Even at constant speed, circular motion involves constant acceleration. Your velocity is always changing direction, even if its magnitude stays the same. This is what you feel when a car rounds a sharp bend or a rollercoaster carves through a loop. This resource introduces centripetal acceleration and the centripetal force...

- Chemical bonding
Covalent bonding is responsible for creating many substances we encounter in our daily lives. Water (\(\ce{H2O}\)) is essential for life, carbon dioxide (\(\ce{CO2}\)) is a key component of the Earth's atmosphere, and methane (\(\ce{CH4}\)) is a common fuel source. Use this resource to learn more about how covalent bonds form,...

In everyday life, forces are all around us, from the push of your feet on the ground when you start walking, to the pull of gravity that keeps you on Earth. Newton’s three laws of motion describe how these forces affect the way objects start moving, keep moving, or come...

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...
