velocity \(= m/sec ;\)  in new system  \(= \frac{{100m}}{{100\sec }} = \frac{m}{{\sec }}\) (same)

force \( = \frac{{kg \times m}}{{{{\sec }^2}}}\); in new system \( = \frac{1}{{10}}kg \times \frac{{100m}}{{100\sec \, \times \,100\sec }}\) \( = \frac{1}{{1000}}\,\frac{{kg \times m}}{{{{\sec }^2}}}\)

energy \( = \frac{{kg \times {m^2}}}{{{{\sec }^2}}}\) ; in new system \( = \frac{1}{{10}}kg \times \frac{{100m \times 100m}}{{100\sec \, \times \,100\sec }}\) \( = \frac{1}{{10}}\frac{{kg \times {m^{\rm{2}}}}}{{se{c^2}}}\)

pressure \( = \frac{{kg}}{{m \times {{\sec }^2}}}\); in new system \( = \frac{1}{{10}}kg \times \frac{1}{{100}}m \times \frac{1}{{100\,sec \times 100\,sec}}\) \( = {10^{ - 7}}\frac{{kg}}{{m \times se{c^2}}}\)
