Study Notes
Types of Motion
- Translational Motion: motion in which an object moves from one place to another in a straight line or curved path.
- Rotational Motion: motion in which an object rotates around a fixed axis.
- Vibrational Motion: motion in which an object oscillates back and forth about a fixed point.
- Circular Motion: motion in which an object moves in a circular path.
- Random Motion: motion in which an object moves in a random and unpredictable way.
Describing Motion
- Distance: the total length of the path traveled by an object.
- Displacement: the shortest distance between the initial and final positions of an object.
- Speed: the rate of change of distance with respect to time.
- Velocity: the rate of change of displacement with respect to time.
- Acceleration: the rate of change of velocity with respect to time.
Motion Graphs
- Distance-Time Graph: a graph that shows the distance traveled by an object over time.
- Velocity-Time Graph: a graph that shows the velocity of an object over time.
- Acceleration-Time Graph: a graph that shows the acceleration of an object over time.
Equations of Motion
- v = u + at: the equation of motion that relates initial velocity (u), final velocity (v), acceleration (a), and time (t).
- s = ut + (1/2)at^2: the equation of motion that relates displacement (s), initial velocity (u), acceleration (a), and time (t).
- v^2 = u^2 + 2as: the equation of motion that relates initial velocity (u), final velocity (v), acceleration (a), and displacement (s).
Motion in a Straight Line
- Uniform Motion: motion in which an object moves with a constant velocity.
- Uniformly Accelerated Motion: motion in which an object moves with a constant acceleration.
- Free Fall: motion in which an object falls under the sole influence of gravity.
Types of Motion
- Translational motion involves an object moving from one place to another in a straight line or curved path.
- Rotational motion occurs when an object rotates around a fixed axis.
- Vibrational motion is a type of motion where an object oscillates back and forth about a fixed point.
- Circular motion involves an object moving in a circular path.
- Random motion is a type of motion where an object moves in a random and unpredictable way.
Describing Motion
- Distance is the total length of the path traveled by an object.
- Displacement is the shortest distance between the initial and final positions of an object.
- Speed is the rate of change of distance with respect to time, measured in meters per second (m/s).
- Velocity is the rate of change of displacement with respect to time, measured in meters per second (m/s).
- Acceleration is the rate of change of velocity with respect to time, measured in meters per second squared (m/s²).
Motion Graphs
- Distance-time graphs show the distance traveled by an object over time.
