Please help! Is anyone taking physics on edmentum/plato??? I need help with some the unit activities... Unit 1: kinematics 1
Unit 2: Kinematics 2
Unit 3: Dynamics

the binding energy is the energy required to create z separate protons and n=a-z separate neutrons from a (a,z) nucleus in its ground state. another way to think about it is binding energy is the mass energy which is missing from a nucleus compared to the mass energy of the individual nucleons.

the force on the thing and the distance the force moves the thing

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
