Introduction
Motion is found everywhere in nature. Examples include butterflies flying, snakes slithering, horses galloping, dust particles moving in sunlight, clouds gathering, tides rising and falling, and planets moving in space.
Since many motions around us are complex, scientists first study motion in simpler forms. In this chapter, we mainly study:
- Motion in a straight line
- Graphical representation of motion
- Kinematic equations
- Motion in a plane
- Uniform circular motion
Motion can be described using words, numbers, equations, and graphs.
