A Freebody diagram is foreign object is shown in the figure. FA = 420 N, FB = 300 N, FC = 275N, and FD = 295N. Assume angle left = 31degrees, and alpha =13 degree. How much work in (J) does FA do on the object if it moves 2.9 m downward?
Kinematics
A machine is a device that accepts energy in some available form and utilizes it to do a type of work. Energy, work, or power has to be transferred from one mechanical part to another to run a machine. While the transfer of energy between two machine parts, those two parts experience a relative motion with each other. Studying such relative motions is termed kinematics.
Kinetic Energy and Work-Energy Theorem
In physics, work is the product of the net force in direction of the displacement and the magnitude of this displacement or it can also be defined as the energy transfer of an object when it is moved for a distance due to the forces acting on it in the direction of displacement and perpendicular to the displacement which is called the normal force. Energy is the capacity of any object doing work. The SI unit of work is joule and energy is Joule. This principle follows the second law of Newton's law of motion where the net force causes the acceleration of an object. The force of gravity which is downward force and the normal force acting on an object which is perpendicular to the object are equal in magnitude but opposite to the direction, so while determining the net force, these two components cancel out. The net force is the horizontal component of the force and in our explanation, we consider everything as frictionless surface since friction should also be calculated while called the work-energy component of the object. The two most basics of energy classification are potential energy and kinetic energy. There are various kinds of kinetic energy like chemical, mechanical, thermal, nuclear, electrical, radiant energy, and so on. The work is done when there is a change in energy and it mainly depends on the application of force and movement of the object. Let us say how much work is needed to lift a 5kg ball 5m high. Work is mathematically represented as Force ×Displacement. So it will be 5kg times the gravitational constant on earth and the distance moved by the object. Wnet=Fnet times Displacement.
![### 3D Vector Representation with Spherical Coordinates
The image presents a three-dimensional vector diagram, which is commonly used in physics and mathematics to represent vectors in space with spherical coordinates. The diagram consists of four vectors originating from a common point, indicated by a blue circle. These vectors are labeled A, B, C, and D, distinguished using different colors for clarity:
- **Vector A** – Red
- **Vector B** – Green
- **Vector C** – Purple
- **Vector D** – Black
Two angles are marked to define the orientation of these vectors:
1. **Angle φ (phi)**: This angle lies in the horizontal plane and is measured from the positive x-axis (C) to the projection of vector A on this plane. In this diagram, it is the angle between the red vector (A) and the dashed horizontal reference line.
2. **Angle α (alpha)**: This angle is measured between the projection of vector B (green) onto the horizontal plane and the vector itself (B). It represents the elevation angle from the horizontal plane to the vector.
### Description of Vectors:
- **Vector A** (Red): It is oriented upwards and to the left at an angle φ relative to the dashed horizontal line.
- **Vector B** (Green): It is oriented upwards and to the right forming an angle α with Vector C (Purple).
- **Vector C** (Purple): This vector lies horizontally to the right.
- **Vector D** (Black): This vector points directly downward.
### Concepts Illustrated:
- **Vector Components**: This diagram helps in visualizing how a vector can be broken down into its components along different axes.
- **Spherical Coordinates**: The angles α and φ are used to describe the vector's orientation in 3D space, essential in converting between Cartesian and spherical coordinate systems.
This representation is essential for understanding various physical phenomena, such as forces, electric and magnetic fields, and the movement of objects in space.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcdce31da-09da-4c4c-8ce9-9517d7b65c94%2Fd3a0deee-749e-4e13-a2ce-604e52d9a22b%2Fqfnvzgf_processed.jpeg&w=3840&q=75)
