Motion Along a Straight Line

Average speed

Average speed Average speed  is a different way of describing how fast a particle moves. Whereas the average velocity involves the particle’s displacement  the average speed involves the total distance covered (for example, the number of meters moved). independent of direction  that is. Because average speed does not include direction. it lacks any algebraic sign. Sometimes the same (except …

Motion The world, and everything in it, moves. Even seemingly stationary things, such as  a roadway, move with Earth’s rotation, Earth’s orbit around the Sun.the Sun’s orbit. around the center of the Milky Way galaxy, and that galaxy’s migration relative to other galaxies. The classification and comparison of motions (called kinematics) is often challenging. What exactly do you …
