SUMMARY

The discussion focuses on the physics problem of determining the relationship between the Newton scale reading and the horizontal component of the force exerted by a mass in a pulley system. The user provides specific parameters: a mass of 0.1 kg, a distance of 0.1 m, an angle of 70 degrees, and a Newton scale reading of 0.2 N. To find the horizontal component of the force, the user correctly identifies the formulas Fx = F cos(theta) and Fy = F sin(theta) as essential for calculations. The confusion arises regarding the terminology of "mass" in the context of the problem.

PREREQUISITES
  • Understanding of basic physics concepts, particularly forces and components.
  • Familiarity with trigonometric functions, specifically cosine and sine.
  • Knowledge of Newton's laws of motion and their application in pulley systems.
  • Ability to perform calculations involving mass, force, and angles.
NEXT STEPS
  • Study the principles of force decomposition in physics.
  • Learn how to apply trigonometric functions in real-world physics problems.
  • Explore the dynamics of pulley systems and their force interactions.
  • Review Newton's laws of motion with a focus on practical applications in lab settings.
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and force analysis, as well as educators seeking to clarify concepts related to force components in pulley systems.

Hi ppl..

I have to hand this questions about Physics on Dec 6th.. & I really need help on it... Plz if possible answer this question. I will love to help someone in other way. Thx in advance :)

This is a question on Lab:Angle dependence of work

1) What is the relationship between the Newton scale reading and the horizontal component of the force exerted by the mass?

2) how to find horizontal component of the force mass?
 
Physics news on Phys.org
if u are given an angle, then just use Fx = F cos theta, Fy = F sin theta
 
Thx for reply ,, BuT

I do have an angle.. for the first part i have 0.1 kg, distance=0.1m, angle=70*, N=0.2

but the question asks for Horizontal component of the force mass. Y does it say mass??

this is about the cart pulled away by Newton's scale and mass hangin over the pulley problem.

and you wht is the relationship between Newton scale reading and horizontal component of the force exertd by the mass ?

Do I use m*N?
