Table of Nutritional Content The FDA requires fast food companies to publish the nutritional content of their meals. The above table shows the fat, carbohydrate, and protein content (in grams) for three popular items, and the total calories in each item. Set up a matrix equation to find the calories per gram for fat, carbohydrates, and protein: Calories per gram: Fat: Carbohydrate: Protein:

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
