What is average velocity?

The total displacement, the change in position, divided by the total time taken. It considers both magnitude and direction.

Study Notes

Uniform Motion (RP)

Uniform motion (RP): Motion along a straight line at constant velocity
Described by a straight-line graph of position versus time
Velocity (v) is constant
Displacement (s) is proportional to time (t)
Equation: s = vt
Graph of position (s) versus time (t) is a straight line with a slope equal to the velocity (v)
If velocity (v) is positive, the object moves in the positive direction along the x-axis. If velocity (v) is negative, the object moves in the negative direction along the x-axis.
A horizontal line on a position-time graph indicates constant velocity and zero acceleration

Types of Motion

Rectilinear (along a straight line)
Curvilinear (along a curved path)
Rotational
Oscillatory

Different Ways to Describe Motion

Position (s)- the location of an object from a reference point.
Velocity (v)- the rate of change of position regarding time; it is a vector quantity
instantaneous velocity
average velocity
Acceleration (a)- rate of change of velocity with respect to time; it is a vector quantity.
average acceleration
instantaneous acceleration
