Glossary

Acceleration: The rate at which an object’s velocity changes, often caused by a force acting on it.
Chemical Energy: The energy stored in the chemical bonds within substances such as fuels and batteries. It can be released and transformed into other forms like kinetic energy.
Charge: A measure of the amount of electric charge that flows in a circuit, measured in coulombs (C).
Current: The flow of electric charge around a circuit, measured in amperes (A).
Displacement: The distance moved by an object in the direction of a force, measured in metres (m).
Elastic Potential Energy: The energy stored when an object such as a spring or rubber band is stretched or compressed.
Electrical Energy: The energy carried by electric currents and transferred when charges move through a potential difference.
Energy: The ability to do work or cause change, stored in different forms and transferred between stores.
Energy Store: A way that energy is kept within a system, such as kinetic, thermal, chemical, gravitational potential, or elastic potential.
Energy Transfer: The movement of energy from one store or system to another, such as by heating, mechanical work, or electrical work.
Extension / Stretch: How much a spring or elastic object is extended or compressed compared to its original length.
Force: A push or pull acting on an object that can cause acceleration, measured in newtons (N).
Gravitational Field Strength: A measure of the force of gravity on an object per kilogram of mass, measured in N/kg.
Gravitational Potential Energy: The energy stored in an object due to its height above the ground. The higher the object, the more gravitational potential energy it stores.
Heating: A process in which thermal energy is transferred from a hotter object to a cooler one.
Height: The vertical distance an object is raised above ground level, measured in metres (m).
Internal Energy: The total energy stored inside a system due to the movement and arrangement of particles.
Kinetic Energy: The energy an object has because it is moving. It increases with mass and speed.
Mass: The amount of matter in an object, measured in kilograms (kg).
Mechanical Work: Energy transferred when a force moves an object over a distance.
Object: A physical item or mass that can store or transfer energy.
Potential Difference: The energy transferred per unit charge when charge moves between two points in a circuit, measured in volts (V).
Power: The rate at which energy is transferred or work is done, measured in watts (W).
Rate: A measure of how quickly a change happens. In physics, power is the rate of energy transfer.
Specific Heat Capacity: The amount of energy needed to raise the temperature of 1 kg of a substance by 1 °C.
Speed: The distance an object travels per unit time, measured in metres per second (m/s).
Spring Constant: A measure of how stiff a spring is. A larger value means a stiffer spring.
System: An object or group of objects that can be studied as a single unit for energy analysis.
Temperature Change: The difference between the final and initial temperature of a system, measured in °C or K.
Thermal Energy: The internal energy stored in a substance due to the motion of its particles. It increases when a system is heated.
Voltage: Another term for potential difference, describing how much energy is transferred per unit charge.
Weight: The force acting on an object due to gravity.
Work Done: The amount of energy transferred when a force moves an object or when charge flows through a potential difference.
