Jan 31, 2023 · Force can be calculated with the formula Work = F × D × Cosine(θ), where F = force (in newtons), D = displacement (in meters), and θ = the angle between the force vector and the direction of motion.

The formula to find the work done by a particular force on an object is W equals F d cosine theta. W refers to the work done by the force F. In other words, W is telling you the amount of energy that the force F is giving to the object.

- Why does one need a cos and theta when we can easily get the work by multiplying F and displacement ...Imagine that your F is at and angle starting at the origin and pointing somewhere between the x and y axis and you distance is along the x axis. To...
- Hi, i'm unclear about why Wnet=0 indicates that an object is maintained at constant. Could someone p..... the condition is that if the object is moving at a constant speed/velocity then the net work will be zero is TRUE. this is bcoz when u move at a...

- What is the exact meaning of 'NET' Force and 'NET' Work?'Net' is used as opposed to 'Gross' because in some systems you get work back. Depending on your sign convention, negative work might be work retur...
- I don't understand 2 things: 1) What are the conditions for when this formula is valid? 2) How does ...Positive work is done on the object by the lifter, but negative work is done on the object by gravity. Therefore, the net work done on the object i...

- why is the cosine theta needed in some cases, and not in other cases? I noticed that cosine theta wa...Cosine theta is applied in every case of "work" because it determines whether the system energy is positive, negative, or 0 (neutral). After that t...
- Where does 1/2 come from?If you mean the 1/2 from mv²/2 , its a factor that appears when you calculate W = ∫F.ds = m.∫a.ds = m∫(dv/dt).ds = m∫dv.(ds/dt) = m∫v.dv = mv²/2
- Why do we need theta when we are finding work as by multiplying force and displacement we can easily...You can't simply multiply force and displacement unless the force is parallel to the displacement. You need the component of the force that is para...
Example: calculating work. A conveyor belt generates a force F= 5i−3j+k F = 5 i − 3 j + k that moves a suitcase from point (1,1,1) ( 1, 1, 1) to point (9,4,7) ( 9, 4, 7) along a straight line. Find the work done by the conveyor belt. The distance is measured in meters and the force is measured in newtons.
Nov 16, 2022 · Therefore, the work to move the volume of water in the \(i\) th subinterval to the top of the tank, i.e. raise it a distance of \(15 - x_i^*\), is then approximately, \[{W_i} \approx {F_i}\left( {15 - x_i^*} \right) = \left( {9.8} \right)\frac{{640}}{9}\pi {\left( {x_i^*} \right)^2}\left( {15 - x_i^*} \right)\Delta x\]
The first formula, work = force * Distance, is used where the force applied is constant. Solving these types of problems is relatively easy. All you have to do is multiply force by distance. Example question: How much work do we need to do to lift a 30 lb box 4 feet off the ground?
W = F → × Δ x. Where W is work, F → is force, and Δ x is the distance., Kinetic Energy: Kinetic energy is the energy of movement. It is based on mass and velocity. It is measured in Joules. K...
In simple terms, work is done when a force moves an object over a distance. Work is a scalar quantity represented by the symbol 'W' and is measured in joules (J) in the International System of Units (SI units). The mathematical formula for calculating work is: W = F × d × cos(θ) where: - W represents the work done, - F is the force applied,
