Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:
1 m/s2 to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg/s2 |
|
1 m/s to a mass of 1 kg |
|
1 mph to a mass of 1 kg |
Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.
The respiratory and circulatory systems are similar in that they:
add carbon dioxide |
|
transport oxygen |
|
transport nutrients |
|
deoxygenate blood |
Like the respiratory system, the circulatory system serves to transport oxygen throughout the body while removing carbon dioxide. In addition, the circulatory system transports nutrients from the digestive system.
