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.
Converting Gallons and Liters. As stated above, one US gallon consists of about 3.785 liters. It means that to convert metric liters to US liquid gallons, you should multiply liters by 0,264. If you want to know how many liters are in some number of gallons, you need to multiply gallons by 3.785. The table below will help you to convert gallons and liters to other units of volume.
