evan b said:What is the work done by the two forces together in moving an object a distance of d = 14 m as shown in the diagram? The magnitude of each force is 7 N.
evan b said:ya, so i found force by sqrt of 7^2 + 7^2. then i multiplied it by 7 and go 69.30 J. What am i doing wrong?
Work is the transfer of energy from one system to another. In physics, it is defined as the product of force and displacement, where the force is applied in the direction of the displacement.
Forces are interactions that cause a change in the motion or shape of an object. They can be either contact forces, such as pushing or pulling, or non-contact forces, such as gravity or magnetism.
Work can be calculated by multiplying the force applied to an object by the distance the object moves in the same direction as the force. In other words, work = force x distance.
The unit of work is the joule (J), which is defined as the amount of work done when a force of 1 newton is applied to an object and moves it a distance of 1 meter in the direction of the force.
When two forces are involved, the work done by each force can be calculated separately and then added together to find the total work done. In the case of two forces at 45 degrees pulling an object a distance of 14, the work done by each force can be calculated using the formula work = force x distance x cosine(theta), where theta is the angle between the force and the displacement.
