Newtons to Newton meters per second

Click For Summary
SUMMARY

The discussion centers on converting Newtons to Newton meters per second in the context of a physics problem involving a mass of 1000 kilograms and a time interval of 0.055 seconds. The user initially miscalculated the conversion by omitting the time component, leading to confusion. The correct approach involves understanding that momentum is calculated as mass multiplied by velocity, and then dividing by time to find the resulting force in Newton meters per second. Clear communication of units and context is essential for accurate problem-solving in physics.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
  • Familiarity with units of force (Newtons) and momentum
  • Basic knowledge of kinematics, including mass and velocity
  • Ability to perform unit conversions in physics
NEXT STEPS
  • Study the relationship between force, mass, and acceleration using Newton's Second Law
  • Learn about momentum and its calculation in various contexts
  • Explore unit conversions involving time, force, and energy
  • Review examples of physics problems that require clear communication of units
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in understanding the conversion of force units in practical applications.

Homework Statement



Ok so 1000(5.556 m/s – 0 m/s)/0.055 = 101018 Newton’s which is a unit of force. We know the force was applied for 1 foot of travel (.3048meters)

Homework Equations


So the incorrect conversion would be to multiply by .3048 to get 30790 Newton meters per second. I am missing the time component

The Attempt at a Solution


Do I need to divide 1 by 0.055seconds and than multiply that number by 30790? Any help would be appreciated I am baffled. Thanks

It's not clear what you are talking about here. Some of the units have been omitted, which muddies the water further. 1000 what? 0.055 what? You've jumped into the middle of something here; we just don't know what.

Ya I definitely stepped in it. Sorry. 1000 is the weight in kilograms, and 0.055 is the time in seconds

Mass * velocity = momentum

momentum / time = ?

Ok I think that helps, Thanks
 
Hi Paulhook. Welcome to Physics Forums.

Part of doing science involves developing and using your communication skills so that people can understand you. We're very good at helping people, but we're not mind readers. Please put yourself in our place, and state your problems so that we can make sense out of them.
