A-LEVEL PHYSICS PAPER 2 (AQA) (LATEST 2025/2026) STUDY GUIDE WITH COMPLETE SOLUTIONS What is internal energy? - -The sum of the potential and kinetic energies of a system. How can you increase the thermal energy of a system? - -We can increase it by heating up or doing work on the object. Explain the energy changes that occur during a change of state. - - During change of state the potential energy of the particles change but the kinetic energies doesn't change.

What is a photomultiplier? - ANSWER A vacuum tube consisting of a photoemissive cathode, a series of intermediate electrodes called dynodes, and a collection anode. What does a single-beam spectrophotometer do? - ANSWER A single-beam spectrophotometer employs one beam of radiation that irradiates one cell. What happens in a deuterium lamp? - ANSWER The lamp energy from the power source produces an excited deuterium molecule that dissociates into two atoms in the ground state and a photon a...

An object of mass is attached to a spring of constant that rests on an inclined plane of angle A. If the spring is elongated by x the force with which the spring is pulling the object is equal to - ️️kx The period of a vertically oscillating ideal spring of constant k and mass m is the same as a horizontally oscillating ideal spring of the same constant and mass. This statement is - ️️true The period of an object attached to a spring oscillating on an inclined plane (no friction) depen...

Thermodynamics Correct Answer-the study of energy and its transformations potential energy Correct Answer-energy stored due to an object's position or arrangement kinetic energy Correct Answer-the energy an object has due to its motion Transfer of energy Correct Answer-occurs when one object gives some or all of its energy to another object. Appears as work (force w) or heat (friction q) Define the surroundings and system Correct Answer-system--> part we focus one surr.--> ...

Linear Momentum and Collisions ANSWERS TO QUESTIONS *Q9.1 (a) No. Impulse, F∆t, depends on the force and the time for which it is applied. (b) No. Work depends on the force and on the distance over which it acts. *Q9.2 The momentum magnitude is proportional to the speed and the kinetic energy is proportional to the speed squared. (i) (ii) The speed of the constant-mass object becomes 4 times larger and the kinetic energy 16 times larger. Answer (a). The speed an...
