Physics Part 1: Vocabulary Heat: the transfer of energy between objects at different temperatures Thermal Energy: the total energy of the particles that make up a substance Conduction: the transfer of thermal energy from one substance to another because of direct contact Convection: The transfer of thermal energy by the movement of a liquid or a gas. Hot rises, cool sinks. Radiation: the transfer of energy through matter or space in the form of electromagnetic waves (light or infrared waves) Wave: Energy that moves back in forth in some substance (called the medium) because of vibration or some motion of electrical charges. Air, water, metal (solids, liquids, and gases can all be mediums) Wave length: The distance between 2 crests of a wave Light- Wavelength affects the color of light Sound- Wavelength affects Amplitude: The height of the wave from resting point to top or Bottom of a crest or trough- the displacement of the medium Frequency: The number of cycles per/unit of time Frequency and amplitude are inversely proportional- the higher the frequency, the lower the wavelength, the higher the energy of the wave. Light- Frequency affects the brightness of the light Sound- Frequency affects the pitch or the sound Force: A push or a pull with a specific size and direction. The unit of measurement for force is the Newton Gravity: A force of attraction between 2 objects that is due to their masses Mass: A measure of the amount of matter in a substance or item Weight: A measure of the gravitational force exerted on an object (Mass +Gravity) Mechanical Energy: A total amount of the energy of movement and position Potential Energy: Energy of an object based on its position or shape. PE=wh (weightxheight) Kinetic Energy: Energy of movement. KE= mv2/2
