Kinematics: Linear Motion in One Dimension Class 1
Distance, Displacement Time Average Speed, Average Velocity
x-t graph
What is the average speed and average velocity for a 1-round swimming in 50s? * Average speed is not the magnitude of average velocity.
Instantaneous Velocity
Motion Diagram
Average and Instantaneous Acceleration “acceleration is to velocity as velocity is to position”
v-t graph
Curvature
Motion without Acceleration
Motion with Constant Acceleration e.g. dripping drops of water from a faucet
The Four Formulae
Freely Falling Bodies acceleration due to gravity, g = 9.8 m/s 2
Motion with Changing Acceleration
Integration
