Answer the following question given this paragraph: In the equation for pressure, force is expressed in newtons (N) and area is expressed in square meters (m 2 ). Therefore, pressure is expressed in N/m 2 , which is the SI unit for pressure. This unit is also called the pascal (Pa) . It is named for the scientist Blaise Pascal, whose discovery about pressure in fluids is described later in this lesson. Pressure may also be expressed in the kilopascal (kPa), which equals 1000 pascals. For example, the correct air pressure inside a mountain bike tire is usually about 200 kPa. Q: In the equation for pressure, how is force expressed? Choices: - meters - pounds - teraflops - newtons A:
newtons
