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.
What is the effect of a changing velocity?
The object experiences acceleration.
What happens when there is a constant velocity?
Acceleration is zero.
What is the effect of a non-zero acceleration?
The velocity of the object changes (either in magnitude or direction).
What is the effect of an object changing direction?
The object is accelerating, even if its speed is constant.
What is the effect of an object speeding up?
The object is accelerating.
What is the effect of a changing velocity?
Acceleration occurs.
What is the effect of integrating an acceleration function with respect to time?
The change in velocity is obtained.
What is the effect of integrating a velocity function with respect to time?
The displacement is obtained.
What happens when the time interval approaches zero when calculating average velocity?
Average velocity approaches instantaneous velocity.
What happens when the time interval approaches zero when calculating average acceleration?
Average acceleration approaches instantaneous acceleration.
