Average velocity

Displacement divided by the time interval over which that displacement occurred.

Displacement indicates

how far an object ends up from its initial position, regardless of its total distance traveled

Instantaneous velocity

Is how far an object is moving in a specific moment in time.

To determine how far from the detector an object is located

Look at the vertical axis of the position time graph

To determine how fast an object is moving

Look at the steepness of the position time graph

Position time slope like a front slash

Means the object is moving away from the detector

Position time slope like a back slash

Means the object is moving towards the detector

instantaneous Velocity is found by

Taking the slope of a tangent line to a position time graph

To determine how fast an object is moving

Look at the vertical axis of the velocity time graph

To determine which way the object is moving

Look at whether the velocity time graph is above or below the horizontal axis

An object is moving away from the detector if

The velocity time graph is above the horizontal axis

An object is moving towards the detector if the velocity time graph is

Below the horizontal axis

To determine how far an object travels

Determine the area between the velocity time graph, and the horizontal axis

On velocity time graph, it is not possible to

Determine the location of the object with the graph alone

The slope of a velocity time graph is

Acceleration
