What is the process for simplifying objects in kinematics?
Model objects as point particles, ignoring size and shape, and focusing on mass and charge.
What is displacement?
The change in an object's position, calculated as final position minus initial position:
Define average velocity.
The rate of change of displacement over a time interval:
What is average acceleration?
The rate of change of velocity over a time interval:
Define instantaneous velocity.
The velocity of an object at a specific moment in time. It is the average velocity over an infinitesimally small time interval.
What is meant by 'object model simplification'?
Treating objects as points, ignoring size, shape, and internal configuration for simplified analysis.
