Friction can be friend or foe. What is friction, how does it affect our lives and how can we alter it? Physics - Forces - Learning Points. Friction is a resistive force between surfaces moving at different velocities. Friction is...

Isaac Newton's Laws of Motion explain how and why objects move as they do - the principles which underlie all of modern mechanics. Physics - Forces - Learning Points. Sir Isaac Newton published his laws of motion in 1687. Every movement...

Explore the reasons why objects can keep moving on their own, and why most of them will eventually stop. Physics - Forces - Learning Points. Momentum is how we quantify a moving object. Outside forces affect momentum. Momentum is...

We interleave the pages of notebooks to see how hard it is to pull them apart. As the amount of interleaving increases, we see that the force required to separate them also increases. This is because the friction between the notebooks is...

We make slime using borax, water and food colouring. The slime is a non-Newtonian liquid. A non-Newtonian liquid can behave like a liquid or a solid depending on the pressure applied to it. Chemistry - Atoms And Bonding - Learning...

We create a polymer using cornflour and water called oobleck. Oobleck is a non-Newtonian liquid that behaves like a solid and a liquid. When placed on a speaker, the vibrations cause the polymer to constantly change its behaviour and it...
