SUMMARY

The discussion clarifies the distinction between the units "lbf" (pound-force) and "lbs" (pound-mass). It establishes that 1 lbf is equivalent to approximately 4.44822 Newtons, while 1 lbs is a measure of mass and does not directly convert to Newtons without considering acceleration. The conversation emphasizes that when discussing force in the context of Newtons, the relevant unit is lbf, not lbs. Additionally, it highlights the importance of understanding the relationship between mass, force, and acceleration in physics.

PREREQUISITES
  • Understanding of basic physics concepts, particularly force and mass.
  • Familiarity with unit conversions, specifically between imperial and metric systems.
  • Knowledge of Newton's second law of motion (F=ma).
  • Basic understanding of the difference between mass and force units.
NEXT STEPS
  • Research the conversion factors between pounds and Newtons, focusing on 1 lbf = 4.44822 N.
  • Study Newton's second law of motion to understand the relationship between mass, force, and acceleration.
  • Explore the implications of using pounds mass (lbs) versus pounds force (lbf) in engineering calculations.
  • Learn about other force measurement units and their conversions, such as poundals and kilograms.
USEFUL FOR

Students of physics, engineers, and anyone involved in fields requiring precise measurements of force and mass, particularly in contexts where unit conversions are necessary.

whats the difeerence between these two units lbf & LBS

1lbs= ? NEWTON

1lbf = ? Newton



can anyone help me...
 
Physics news on Phys.org
It comes down to the way a force is measured.

What do the units lbs and lbf mean in english.
 
i know lbf means pound force... but what does lbs mean is it poundal...
 
oooppps - I was using English definitions not American so got a tourque in there

LBS is the abbreviation for Pounds Mass. (Eng)

LBF is the abbreviation for Pounds Force. (US)

So what can you say is the relationship between them?
 
The problem asks for a relationship between "pounds" and "Newtons". Since the Newton IS a unit of force, they can only mean "pounds" as a unit of force: LBF.
 
ok i have a drawing in which it says force LBS pull... so i need to convert that lbs to Newton... so can anyone say...

1lbs = how many Newton
 
What is the equation for Force?

What is the Mass and what is the acceleration?

What is the definition for 1 Newton? A Mass , An Acceleration

Is the force applied by 1 lb always 1lbf?
 
i want to know the exact value

1lbs = _ N
