How It's Made Rubber Gloves Surgical rubber gloves were first implemented at Johns Hopkins Hospital. Watch this video to see how rubber gloves are made. 02:59.
If the mass m is measured in kilograms and the acceleration a is measured in meters per second squared, then the unit of force is kilogram x meter/second squared. This unit is called the newton: 1 N = 1 kg x 1 m/sÂ².
1 F is force, d is the distance over which the force is applied, and Î¸ is the angle between the force and distance. 2  Derived units, sign conventions. 3  Work is energy, and the unit is the Joule. 4  Joule = NÂ·m = kgÂ·m/s 2 Â·m = kgÂ·m 2 /s 2. 5  If the force and the distance applied is in the same direction, work is positive.
