Kinetic energy (Force and d(x))

Click For Summary
SUMMARY

The discussion focuses on calculating kinetic energy (KE) gained by an object when a force is applied over a distance. Specifically, it addresses two scenarios: applying a 10N force over 5m and a 20N force over 2m. The work done, which translates to KE, is determined using the formula Work = Force × Displacement, resulting in 50 Joules for the first scenario and 40 Joules for the second. Thus, the object gains 50J and 40J of kinetic energy respectively in each case.

Homework Statement



If no energy is dissipated , how much KE does an object gain if
a) A 10N force is applied for 5m
b) A 20N force is applied for 2m

Homework Equations


The Attempt at a Solution


I know there is work being done if an object moves causing it to have KE. I think work is Force * displacement and the units for Force (N) and displacement (m) works out to Joules. So does that mean I use multiply force and displacement to find the amount of KE gained?
