AQA Physics Correct Questions And Answers 2023 Energy is transferred between stores Thermal, kinetic, gravitational potential, elastic potential, chemical, magnetic, electrostatic, nuclear Energy is transferred... Mechanically (by a force doing work), electrically (work done by moving charges), by heating or by radiation (like light or sound) When a system changes, energy is transferred It can be transferred into or away from the system, between objects in the system or between...

GCSE Physics (pp1)Question and answers. Alpha, beta and gamma radiation is ionising. What does it mean? -Answer-Knocks electrons off atoms creating positive ions. At a constant temperature, the current through an ohmic conductor is... -Answer-Directly proportional to the potential difference across the resistor. Bio-fuels made from plants are said to be carbon neutral why? -Answer-CO2 released when the fuel burns is removed from the atmosphere when the plants grow Describe the curren...

IB-Physics-Core-Notes Topic 2 Mechanics 2.1 Kinematics 2.1.1 Define displacement, velocity, speed and acceleration. Displacement- Defined as the change in position of an object. Displacement is a quantity that has both direction and magnitude, it is a vector. Measured in metres. Speed- How far an object travels in a given time. Rate of change of distance (ms-1) Velocity- The vector version of speed. Tells us the magnitude of how fast an object is moving and the direction in wh...
