Study Notes
Introduction to Motion
- A body is said to be at rest when it doesn't change its position with respect to time.
- A body is said to be in motion when it changes its position with respect to time.
Types of Motion
- Rectilinear motion: when a body moves in a straight line direction (e.g., a coin falling from a building, or a sprinter running a 100-meter race).
- Circular motion: when an object follows a circular path of motion (e.g., the moon revolving around the Earth).
- Periodic motion: when an object moves to and fro from a mean or steady position, or repeats the motion (e.g., a pendulum, or a race car taking laps of a circuit).
Measurement of Distances
- Distance is the measure of how far or long something is (e.g., the length of a table, or a football field, or how far Mumbai is from Delhi).
- Length can be measured in terms of a unit, which is a comparison of an unknown quantity with that of a known quantity.
- Units are necessary to establish a common standard or convention worldwide to make calculations and evaluation simpler.
