Study Notes
Motion
Types of Motion
- Translational Motion: Motion of an object from one point to another in a straight line or a curved path.
- Rotational Motion: Motion of an object around a fixed axis.
- Vibrational Motion: Back-and-forth motion of an object around a fixed point.
- Oscillatory Motion: Repetitive motion of an object between two fixed points.
Describing Motion
-
Displacement: Change in position of an object from its initial to its final position.
- Vector quantity (has magnitude and direction)
- Measured in meters (m)
-
Distance: Total length of path traveled by an object.
- Scalar quantity (has magnitude only)
- Measured in meters (m)
-
Speed: Rate of change of distance with respect to time.
- Scalar quantity (has magnitude only)
- Measured in meters per second (m/s)
-
Velocity: Rate of change of displacement with respect to time.
- Vector quantity (has magnitude and direction)
- Measured in meters per second (m/s)
-
Acceleration: Rate of change of velocity with respect to time.
- Vector quantity (has magnitude and direction)
- Measured in meters per second squared (m/s²)
Kinematic Equations
- v = u + at: Equation of motion for an object with initial velocity (u), acceleration (a), and time (t).
- s = ut + (1/2)at²: Equation of motion for an object with initial velocity (u), acceleration (a), and time (t).
- v² = u² + 2as: Equation of motion for an object with initial velocity (u), acceleration (a), and displacement (s).
Graphical Analysis
- Position-Time Graph: Graph showing the position of an object at different times.
- Velocity-Time Graph: Graph showing the velocity of an object at different times.
- Acceleration-Time Graph: Graph showing the acceleration of an object at different times.
Motion in One Dimension
- Uniform Motion: Motion with constant velocity.
- Non-Uniform Motion: Motion with changing velocity.
- Free Fall: Motion of an object under the influence of gravity only.
Motion in Two and Three Dimensions
- Projectile Motion: Motion of an object under the influence of gravity, with both horizontal and vertical components.
- Circular Motion: Motion of an object in a circular path.
- Relative Motion: Motion of an object relative to a reference frame.
