Understanding Linear Motion
Linear motion refers to the movement of an object along a straight path. It can be described in terms of several key physical quantities, including:
- Displacement: The shortest distance from the initial to the final position of an object.
- Velocity: The speed of an object in a specific direction.
- Acceleration: The rate of change of velocity over time.
- Time: The duration over which motion occurs.
These concepts are fundamental in physics and are explored in-depth within linear motion labs.
