Study Notes
Motion in a Straight Line
Types of Motion
- Rectilinear motion: Motion along a straight line
- Translational motion: Motion in which all points of an object move in the same direction and at the same speed
Kinematic Quantities
- Displacement (s): Distance traveled in a specific direction
- Distance (d): Total length of the path traveled
- Speed (v): Rate of change of distance with respect to time
- Velocity (v): Rate of change of displacement with respect to time
- Acceleration (a): Rate of change of velocity with respect to time
Equations of Motion
-
First equation of motion: v = u + at
- v: final velocity
- u: initial velocity
- a: acceleration
- t: time
-
Second equation of motion: s = ut + (1/2)at^2
- s: displacement
- u: initial velocity
- a: acceleration
- t: time
-
Third equation of motion: v^2 = u^2 + 2as
- v: final velocity
- u: initial velocity
- a: acceleration
- s: displacement
Graphical Representation
- Distance-time graph: A graph of distance versus time
- Velocity-time graph: A graph of velocity versus time
- Acceleration-time graph: A graph of acceleration versus time
Motion with Constant Acceleration
- Uniformly accelerated motion: Motion with constant acceleration
- Freely falling bodies: Objects under the sole influence of gravity, with acceleration g = 9.8 m/s^2
Motion in a Straight Line
Types of Motion
- Motion along a straight line is known as rectilinear motion
- Translational motion occurs when all points of an object move in the same direction and at the same speed
Kinematic Quantities
- Displacement is the distance traveled in a specific direction
- Distance is the total length of the path traveled
- Speed is the rate of change of distance with respect to time
- Velocity is the rate of change of displacement with respect to time
- Acceleration is the rate of change of velocity with respect to time
Equations of Motion
- The first equation of motion relates final velocity, initial velocity, acceleration, and time: v = u + at
- The second equation of motion relates displacement, initial velocity, acceleration, and time: s = ut + (1/2)at^2
- The third equation of motion relates final velocity, initial velocity, acceleration, and displacement: v^2 = u^2 + 2as
Graphical Representation
- A distance-time graph plots distance versus time
- A velocity-time graph plots velocity versus time
- An acceleration-time graph plots acceleration versus time
Motion with Constant Acceleration
- Uniformly accelerated motion occurs when an object's acceleration is constant
- Freely falling bodies are objects under the sole influence of gravity, with an acceleration of 9.8 m/s^2
