The potential must have both an attractive and a repulsive component if binding is to occur. The form of the potential energy as a function of lattice spacing (interatomic distance, r) in a solid is ...

When an 80 kg diver climbs to the top of the platform, how much is the increase in energy in their gravitational potential energy store? Energy in the gravitational potential energy store ...

The elastic potential energy stored can be calculated using the equation: A spring has a spring constant, k, of 3 N/m. It is stretched until it is extended by 50 cm. Calculate the elastic ...
