Solving for Work: Tips and Hints | Work Equation Explained

Click For Summary
SUMMARY

The discussion focuses on solving a work-related problem using the equation W=F*d, where W represents work, F is force, and d is distance. A participant expresses confusion about calculating work without a given distance and suggests integrating the force equation with respect to time. Another user clarifies that to find distance, one can use the relationship F=ma, allowing for the calculation of distance by dividing force by mass and integrating acceleration twice. This method provides a clear path to solving the problem effectively.

PREREQUISITES
  • Understanding of the work-energy principle
  • Knowledge of Newton's second law (F=ma)
  • Basic calculus, specifically integration
  • Familiarity with kinematic equations
NEXT STEPS
  • Study the work-energy theorem in physics
  • Learn about integrating force equations over time
  • Explore kinematic equations for motion analysis
  • Practice problems involving force, mass, and acceleration
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the principles of work, force, and motion in a practical context.

Hi, I am new to this forum and to any forums in general. I am not too sure as to how to solve this problem given the shown statements. I know the equation for work is W=F*d but I am not given any distance. The only thing I can think of is to integrate the Force equation with respect to time and plug in my t=5,0 but that won't give me the work. I don't think I can relate this to energy. Can someone give me a hint as to how to solve this problem?

U can find the force by the equation in terms of 5 sec interval. At the same time, u know that F = ma. Therefore, u can find distance d by dividing F by mass and integrate a twice.
