Do batteries contain current, which comes out when they are in a circuit?
No; this is a common misconception! Batteries store energy, which is used to push electrons (charges) around a circuit. The flow of electrons is called current. As the electrons flow through the circuit they lose energy, usually because they're doing some electrical work like driving a motor or making a lightbulb light up!

On a day with no wind, a large object is dropped from a tall building. The object experiences air resistance during its fall to the ground. State and explain, in terms of the forces acting, how the acceleration of the object varies during its fall.
If a box of mass 20kg is being pulled by a force of 50N, and the friction is 10N, what is the resulting acceleration of the box?
(A-level but box won't let me change it from GCSE) A particle of charge q and initial speed v is stopped by a potential difference V in distance d and time t. What was its initial momentum?
