WebVideo transcript. I'm going to show you some examples of how to solve problems involving work. Imagine a 4 kilogram trashcan. The trashcan is disgusting. So someone ties a string to it and pulls on the string with a force of 50 newtons. The force of kinetic friction on the trashcan while it slides is 30 newtons. WebBreakout the gravity force vector into components which are parallel -mg*sin (Θ) and perpendicular -mg*cos (Θ) to the incline. The normal force will be equal and opposite to the perpendicular gravity component so N = +mg*cos (Θ). To keep the block from sliding, you would then need to apply a horizontal force equal and opposite to the ...

WebMar 16, 2024 · The kinetic energy equation is as follows: KE = 0.5 × m × v², where: m – Mass; and. v – Velocity. With the kinetic energy formula, you can estimate how much energy is needed to move an object. The same energy could be used to decelerate the object, but keep in mind that velocity is squared. WebOnce an object is moving, there are fewer points of contact (fewer molecules adhering), so less force is required to keep the object moving.
