We could say, we needed to convert metric items to calculate foot kilos. This may require some unit conversions.
Take into account the situation: You might be finding out a small object. The thing has a mass of 100 grams and is touring at a velocity of 30 meters per second.
- Changing Mass:
- First, convert grams to kilos. There are roughly 453.6 grams in a pound.
- 100 grams / 453.6 grams/lb ≈ 0.22 kilos
- Changing Velocity:
- Subsequent, convert meters per second to toes per second. There are roughly 3.28 toes in a meter.
- 30 m/s * 3.28 ft/m ≈ 98.4 fps
- Apply the components with transformed values:
- KE = 0.5 * 0.22 lbs * (98.4 fps)²
- KE = 0.5 * 0.22 lbs * 9682.56 fps²
- KE = 0.5 * 2129.36
- KE = 1064.68 ft-lbs
The important thing level right here is to all the time use the right items earlier than making use of the kinetic power components. Be certain that your items match with the items anticipated.
