I need a few formula's- High School Physics on Work/Energy etc

Click For Summary
SUMMARY

This discussion focuses on the need for specific equations related to work and energy in high school physics. The user, nicholz, requests formulas to calculate Work Output (J), Work Input (J), and Efficiency based on given variables: Fg (N), h (m), Fa (N), and d (m). The community emphasizes the importance of demonstrating prior understanding and effort before seeking assistance, aligning with forum guidelines.

PREREQUISITES
  • Understanding of basic physics concepts such as force, work, and energy.
  • Familiarity with the equations for calculating work and efficiency.
  • Knowledge of units of measurement in physics (e.g., Newtons, Joules, meters).
  • Ability to interpret and manipulate algebraic equations.
NEXT STEPS
  • Research the equation for Work Output: Work Output = Fg * h.
  • Learn the formula for Work Input: Work Input = Fa * d.
  • Study the concept of Efficiency: Efficiency = (Work Output / Work Input) * 100.
  • Review high school physics notes on energy conservation and work-energy principles.
USEFUL FOR

High school students studying physics, educators teaching work and energy concepts, and anyone preparing for exams in physics-related subjects.

Hi guys.

I need a few equations to complete a table.

I am given numbers for:
Fg (N)
h (m)
Fa (N)
d(m)

and I need to find:
Work Output (J)
Work Input (J)
Effeciency

If anyone has those three equations I could use it would be greatly appreciated.

Welcome to PF nicholz,

We need some idea of what your talking about first. Secondly, the forum guidelines say that you need to show some working and/or thoughts before we can assists you. So what ideas do you have? Have you looked at your class notes?
