Study Notes
Types of Motion
- Rectilinear Motion: Motion in a straight line.
- Circular Motion: Motion in a circular path.
- Rotational Motion: Motion around a fixed axis.
- Oscillatory Motion: Repetitive back-and-forth motion.
- Random Motion: Unpredictable and irregular motion.
Describing Motion
- Displacement: Change in position of an object from initial to final position.
- Distance: Total length of path traveled by an object.
- Speed: Rate of change of distance with time.
- Velocity: Rate of change of displacement with time.
- Acceleration: Rate of change of velocity with time.
Motion Graphs
- Distance-Time Graph: A graph that shows distance traveled vs. time.
- Velocity-Time Graph: A graph that shows velocity vs. time.
- Acceleration-Time Graph: A graph that shows acceleration vs. time.
Equations of Motion
- v = u + at: Calculates final velocity (v) given initial velocity (u), acceleration (a), and time (t).
- s = ut + (1/2)at^2: Calculates displacement (s) given initial velocity (u), acceleration (a), and time (t).
- v^2 = u^2 + 2as: Calculates final velocity (v) given initial velocity (u), acceleration (a), and displacement (s).
Force and Motion
- Newton's First Law: An object at rest remains at rest, and an object in motion remains in motion, unless acted upon by an external force.
- Newton's Second Law: Force (F) is equal to the mass (m) of an object multiplied by its acceleration (a): F = ma.
