The straight-line distance between an object's starting point and its ending point. • Types of movement Includes straight movement, curvilinear movement, elliptical movement, and parabolic movement. • What is velocity? The change in an object's position over an instant, considering its direction. • Effects of force Force can cause changes in form (temporary or undefined), alter velocity, and affect balance. • Magnitude with measurement units Magnitude refers to quantities such as: - Mass (kg) - Time (s) - Volume (m³) - Temperature (K) - Speed (m/s) • Movement units - Kilogram (kg) - Second (s) - Cubic meter (m³) - Kelvin (K) • What are stars? Large celestial bodies composed mainly of hydrogen and helium that emit light and heat. • Definition of the universe Our galaxy is called the Milky Way. A star's explosion is known as a supernova. Galaxy clusters are irregular groups of galaxies. • What are nebulae? Clouds of gas, dust, and diffuse matter in space. • Collisions in the universe Collisions between galaxies are...
