Acceleration
Feet per second square ARE the units in this case.
Initial velocity can be measured in the same units as any other velocity. In SI, that would be meters per second, but often km / hour are used, or (in a minority of countries) feet/second or miles/hour.
feet
Impossible because area is measured in square units whereas volume is measured in cubic units.
FEET
Speed can be measured in units such as meters per second (m/s) or kilometers per hour (km/h).
Velocity is a vector quantity, meaning that it has both a magnitude and a direction. Mass, on the other hand, is a scalar quantity; it has a magnitude only. Velocity is measured in units of distance divided by time; for example, meters per second or miles per hour.
Speed or velocity can be measured in a number of units. Miles per hour, feet per second, metre per second.
They must have compatible units of measure. For example, you cannot directly add a quantity measured in meters to a quantity measured in centimeters. If their units of measure are compatible but not identical, one can be converted to the other. On the other hand, there is no way to add a quantity in feet to a quantity in pounds, as those are incompatible units of measure. Additionally, if the quantities are fractions, they must also have the same denominators, also called sharing a common denominator.
An area is measured in square units, so for lengths measured in feet, the area would be measured in square feet.The surface area of a box, is just the sum of the areas of each face, each of which is measured in square units.
Feet per second square ARE the units in this case.
In SI, acceleration is measured in meters / second2, or meters / second / second. In other units, units of the same dimension have to be used, i.e., [length] / [time] / [time]. For example, in the imperial units, feet per square second is quite common.
The amount that something can hold refers to its capacity or volume, which describes the maximum quantity or volume of material it can contain. This can be measured in units such as liters, gallons, or cubic feet, depending on the item being measured.
Jerk is measured in (distance) per (unit of time) cubed; for example, feet/second cubed.
It could me any measure of volume per time. In the USA it is commonly measured as Cubic-Feet per Second.
Air velocity is typically measured in units of meters per second (m/s) or feet per minute (ft/min).
Area is measured in square units - volumeis measured in cubic units
