One velocity will be positive, and the velocity in the other direction will be negative. The vertical axis of a velocity-time graph is the velocity of the object and the horizontal axis is the time taken from the start. Features of the graphs. When an object is moving with a constant velocity, the line on the graph is horizontal. When an object is moving with a steadily increasing velocity, or a steadily decreasing velocity, the line on the graph is straight, but sloped. The diagram shows some typical lines on a velocity-time graph. Speed - time graph The steeper the line, the more rapidly the velocity of the object is changing.
Quick Answer. There are 3.79 liters in a U.S. gallon. In the British Imperial system of measurement, which is more prevalent in Canada and the U.K., there are 4.54 liters in a gallon. The imperial gallon is equal to roughly 1.2 U.S. gallons.
The US fluid ounce equals to about 29.6 milliliters, and the imperial fluid ounce equals to about 28.4 milliliters. Currently, there are two main definitions of the gallon: the imperial gallon (approximately 4.54 liters) and the US liquid gallon (approximately 3.78 liters). There is also the US dry gallon (approximately 4.4 liters), but it is a rare unit.
