MOTION in a straight line (1-Dimension

Kinematics Equation

links time, position, velocity, accelaration

One-Dimensional Motion

driving in a straight live

• either moving forward/backward or east/west

Time

how long you were driving/moving for

Position

lets you know where you are

• can be negative

• either forward/backward

• either west/east

Displacement

change in position

can be positive or negeative

Velocity

way your position change over time

tells which direction (based on its positivity or negativity)

Acceleration

rate of change of its velocity

m/s²

Position-Time Graph

position (y-axis), time (x-axis)

instantaneous speed

speed of an object at a particular time

instantaneous velocity

speed of an object with its direction at a particular time
