Motion but for our hamburger example, the force already The force in the direction of motion and only thatĬomponent of force that's directed in the direction of Theta, this just makes sure that you're singling out In the direction of motion times the displacement or youĬould say the entire force times displacement times cosine theta. ![]() I'm doing this is because there's gonna be a geometrical It was a constant amount of force, and the reason Moved five meters to the right and we exerted a constantįorce of four newtons, That's why this is a horizontal line. Hamburger to the right, so if we were to plot what the force was on our hamburger as aįunction of its position, it would look something like this. We exerted a force of four newtons for the entire five meters that we pushed this Instead of just plugging straight in, consider the fact that Way to think about this, because what we learn from this alternate approach is gonna help us in more challenging, complicated work examples. Simple problem we can just plug straight into the work formula,īut I'm not gonna do that. ![]() So a question we get asked would be how much work did we do in passing this hamburger to the person to our right? Now since this is a pretty With a force of four newtons and you're gonna do thisĪnd you're gonna push this a distance of five meters to the right. So you're gonna push this hamburger to the right, Maybe you found someone that needs it more than you do, Maybe it's because you're a vegetarian, maybe you're already full, Hamburger sitting right in front of you, but you don't want it.
