Study Notes
Motion
Types of Motion
- Translational Motion: Object changes its position in a straight line or a curved path.
- Rotational Motion: Object rotates around a fixed axis.
- Vibrational Motion: Object oscillates about a fixed point.
- Circular Motion: Object moves in a circular path.
Kinematics
-
Displacement: Change in position of an object.
- Measured in meters (m)
- Vector quantity
-
Velocity: Rate of change of displacement.
- Measured in meters per second (m/s)
- Vector quantity
-
Acceleration: Rate of change of velocity.
- Measured in meters per second squared (m/s^2)
- Vector quantity
-
Speed: Magnitude of velocity.
- Measured in meters per second (m/s)
- Scalar quantity
- Time: Measured in seconds (s)
Equations of Motion
-
Uniform Acceleration:
- v = u + at
- s = ut + (1/2)at^2
- v^2 = u^2 + 2as
-
Uniform Velocity:
- s = vt
- v = constant
