Lesson+2+-+Forces+in+the+nucleus

=Objective= = = =Content=
 * The understand the strengths of the Electromagnetic and gravitional forces in the structure of the nucleus
 * realise that a new force is required to explain the nuclear structure
 * Investigating the density of the nucleus using the mass and nucleon numbers and show that the nuclear density is constant through out all nuclear - implying that nucleons cannot be compressed and thus showing that a nuclear force does not attract for very short distance.
 * The necessary features of a strong force
 * Calculate the magnitude and direction of the electromagnetic and gravitational forces within the nucleus.
 * Understand that a new Strong Force is required to hold the nucleus together - Forces in the Nucleus
 * Plot Mass Number vs Nuclear radius - Consider the possible likely relationships
 * Plot A1/3 vs R - Consider the possible consequences now...for a nuclear force at distances inside the nucleus
 * Consider the consequences from nuclear scattering experiments - the short range of the force
 * How the Strong Force must behave. What values do we have etc.
 * The shape of the potential well and the force curve.
