acceleration
A straight line.
change in velocity
a) A circle is not the graph of a function. b) A circle is not linear.
Magnitude of acceleration (but conveys no informationregarding acceleration's direction).
acceleration
Indirectly, yes. If the graph is a straight line there is no acceleration, if the graph is not linear there is acceleration.
A straight line.
One of the most common ways to represent linear equations is to use constants. You can also represent linear equations by drawing a graph.
The slope of a speed-time linear graph represents acceleration. It indicates how quickly the speed of an object is changing over time.
The slope of a velocity-time graph represents acceleration.
change in velocity
Not necessarily. The equation of a projectile, moving under constant acceleration (due to gravity) is a parabola - a non-linear equation.
