Essential Concepts in Motion and Measurement
- The center point of rotation is known as the axis of rotation, as seen in the example of a swing on a merry-go-round.
- Circular motion involves moving in a circle, like a toy on a railway track, with the Earth rotating around the Sun as an example.
- The distance from the center of a circular path to the body is called the radius, with all distances being equal.
- Oscillatory motion, exemplified by a pendulum's movement, involves repeated motion around a position of rest.
- The Earth's rotation around its axis takes 24 hours, while its revolution around the Sun takes 365 days.
- Understanding standard units, measuring length accurately, and different types of motion are essential concepts in motion and measurement of distance.
