Describe 2 out of 3 of Newton's laws of motion
First Law: States that an object at rest tends to stay at rest and that an object in motion will remain in motion.
Second Law: Both the force and the acceleration of an object are related. F=m x a
Third Law: For every action force, there is an equal and opposite reaction force.

Describe the difference between series and parallel circuits
Series circuits feature a single path for current, where components are connected end-to-end, meaning current is constant but voltage drops across each load. Parallel circuits offer multiple paths for current, sharing the same voltage across components,
