\( Kinetic \ energy = \frac{1}{2} \times mass \times velocity^{2}\) ...

A long time ago a formula was devised for calculating kinetic energy, the energy needed to move a body from one place to another. This energy (E) was dependent on both the mass (M) of the body and the ...

A red and a blue snooker ball both have a mass of 160 g. They collide with speeds and directions as shown in this diagram. The following steps show you how to calculate the velocity of the red ball ...

Springs are a common device for storing energy. A spring which is compressed from its by an amount x from its equlibrium length exerts a force This work represents energy transferred to the spring and ...
