A torque curve is a plot of torque produced vs RPM, as measured on a dynamometer. It usually is not linear (a straight line).
a linear curve does not represent x^2
The production possibility curve is not always linear, in fact, it is usually concave down (bowed-in). The shape of the curve depends on the substutability of the goods described by the curve in the question. When goods are perfectly substitutable in production, the PPP (or PPF) is linear.
Example of a Linear Demand Curve
A Linear Demand Curve Diagram is a diagram that shows how an object or person is shown from youngest to oldest or tallest to shortest
Is negatively sloped linear curve
Along a linear demand curve elasticity varies from point to point of the demand curve with respect to different price, but slope is constant
It is a local maximum for a non-linear curve, which may be a periodic curve.
Linear is a straight line and non linear could be a curve or anything but a straight line
mass
If v (velocity) is constant, then it's straight (linear). If v is changing due to acceleration, then it is a curve (non-linear)
