The bird must travel against air resistance, therefore energy is transferred from the bird's kinetic store to its thermal store and dissipated to the thermal store of the surroundings Air resistance (drag) does work against the bird as it flies through the air
What is the work done by air resistance on the ball? Assuming that the air resistance performs roughly the same job during the descent, calculate the speed of the ball when it returns to the starting point. How do I calculate the work of the air resistance?
The work done equation. The amount of work that is done is related to the magnitude of the force and the distance moved by the object in the direction of the force. To calculate the amount of work done on an object by a force, the work done equation is used: W = f × d.
The term −Rx in equation (3) is the work done by the resistance. The negative sign occurs since the direction of the force is opposite to the direction of motion.
To calculate the work done by a force 𝐹𝐹 on an object: 𝑊𝑊𝑊𝑊𝑊𝑊𝑊𝑊 𝐷𝐷𝑊𝑊𝐷𝐷𝐷𝐷= You may sometimes be asked to calculate the “work done against gravity”, when a particle is raised vertically.
20 lut 2022 · The calculated total work \(W_{total}\) as the sum of the work by each force agrees, as expected, with the work \(W_{net}\) done by the net force. The work done by a collection of forces acting on an object can be calculated by either approach.
This video will show you how to calculate the work done by air resistance (a non-conservative force) on a spaceship.If you think the video is helpful, please...
