- Unit 5: Simple MachinesSimple machines are basic mechanical devices that make work easier by allowing us to apply force more effectively. They include tools like levers, pulleys, wheels and axles, inclined planes, screws, and wedges. Each type of simple machine reduces the effort needed to perform tasks, often by changing the direction or magnitude of the applied force.16

- Unit 6: Mechanical Oscillation and Sound WaveMechanical oscillation refers to the repetitive back-and-forth movement of an object around a central point or equilibrium position. Examples include the swinging of a pendulum or the vibration of a guitar string. A sound wave is a type of mechanical wave that travels through a medium, such as air, water, or solids, as a result of vibrating particles. Sound waves are longitudinal, meaning the particles in the medium move parallel to the direction of the wave's propagation.16

- Unit 7: Temperature and ThermometryMeasures how hot or cold an object is, indicating the average kinetic energy of particles in a substance. Higher temperature means more energetic particles. The science of measuring temperature using instruments like thermometers. Common temperature scales include Celsius, Fahrenheit, and Kelvin. Thermometers work by sensing changes in physical properties, such as the expansion of liquids (mercury, alcohol) or resistance in electronic sensors, corresponding to temperature changes.12
