Crank: The stimulant methamphetamine. Synonyms include meth, speed, chalk, white cross, fire, and glass. “Crystal methamphetamine is called ice,” says Cleveland Clinic’s Pollock.

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement.

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.

Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity – it is the speed of an object in a particular direction.

The speed of an object is how far the object travels in one unit of time. The formula for speed is: speed = distance time. The most common units of speed are metres per second (m/s), kilometres per hour (km/h) and miles per hour (mph).

The formula for speed is speed = distance ÷ time.

The SI unit of mass is the kilogram (kg). In science and technology, the weight of a body in a particular reference frame is defined as the force that gives the body an acceleration equal to the local acceleration of free fall in that reference frame.

The seven SI base units, which are comprised of:

• Length – meter (m)
• Time – second (s)
• Amount of substance – mole (mole)
• Electric current – ampere (A)
• Temperature – kelvin (K)
• Luminous intensity – candela (cd)
• Mass – kilogram (kg)

The Metric System of Measurements uses the mass units: gram (g), kilogram (kg) and tonne (t).

In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity.

The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon.

F = m * a. Fw = m * 9.8 m/s^2. Fw = 30 kg * 9.8 m/s^2 = 294 N. To change from weight to mass divide by gravity (9.8 m/s^2).

Kilogram (kg), basic unit of mass in the metric system. A kilogram is very nearly equal (it was originally intended to be exactly equal) to the mass of 1,000 cubic cm of water.

newtons

In the customary system of measurement, the most common units of weight are the ounce (oz) and pound (lb).

Pascal

Types of pressure: Absolute pressure, gauge pressure, differential pressure, Vacuum Pressure Sensor

• Absolute pressure. The clearest reference pressure is the pressure zero, which exists in the air-free space of the universe.
• Atmospheric pressure.
• Differential pressure.
• Overpressure (gauge pressure)
• Contact us.

Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2). Pascal is a so-called coherent derived unit in the SI with a special name and symbol.

Pascal’s law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.

A pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared. This unit is inconveniently small for many purposes, and the kilopascal (kPa) of 1,000 newtons per square metre is more commonly used.

Hydraulic systems are capable of moving heavier loads as well as providing greater force than mechanical, electrical or pneumatic systems. The fluid power system means it can easily cope with a large weight range without having to use gears, pulleys or heavy leavers.

The unit of viscosity is newton-second per square metre, which is usually expressed as pascal-second in SI units.

The poiseuille (symbol Pl) has been proposed as a derived SI unit of dynamic viscosity, named after the French physicist Jean Léonard Marie Poiseuille (1797–1869). Liquid water has a viscosity of 0.000890 Pl at 25 °C at a pressure of 1 atmosphere (0.000890 Pl = 0.00890 P = 0.890 cP = 0.890 mPa⋅s).
