On a two dimensional diagram, sometimes a vector perpendicular to the plane of the diagram is desired. These vectors are commonly shown as small circles. A circle with a dot at its centre (Unicode U 2299 ⊙) indicates a vector pointing out of the front of the diagram, toward the viewer.

X and Y ponents of a Force Vector. Back Trigonometry Vectors Forces Physics Contents Index Home. This article discusses the x and y components of a force vector. Understand that the diagrams and mathematics here could be applied to any type of vector such as a displacement, velocity, or acceleration vector.

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate.Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

Using Trigonometry to Determine a Vector's Direction. The direction of a resultant vector can often be determined by use of trigonometric functions. Most students recall the meaning of the useful mnemonic SOH CAH TOA from their course in trigonometry.

Right hand ruleThe ordinary, or dot, product of two vectors is simply a one dimensional number, or scalar. In contrast, the cross product of two vectors results in another vector whose direction is orthogonal to both of the original vectors, as illustrated by the right hand rule.

The Weak Force. One of the four fundamental forces, the weak interaction involves the exchange of the intermediate vector bosons, the W and the Z.Since the mass of these particles is on the order of 80 GeV, the uncertainty principle dictates a range of about 10 18 meters which is about 0.1% of the diameter of a proton.. The weak interaction changes one flavor of quark into another.

Introduction: In this lesson we will examine a combination of vectors known as the dot product. Vector components will be combined in such a way as to result in a scalar (number). Applications of the dot product will be shown. Definitions: In general, if v = (v 1, v 2) and u = (u 1, u 2), the dot product. In three dimensions if v = (v 1, v 2, v 3) and u = (u 1, u 2, u 3), the dot product.

As mentioned earlier in this lesson, any vector directed at an angle to the horizontal (or the vertical) can be thought of as having two parts (or components).That is, any vector directed in two dimensions can be thought of as having two components. For example, if a chain pulls upward at an angle on the collar of a dog, then there is a tension force directed in two dimensions.

Coulomb's Law Like charges repel, unlike charges attract. The electric force acting on a point charge q 1 as a result of the presence of a second point charge q 2 is given by Coulomb's Law: where ε 0 = permittivity of space. Note that this satisfies Newton's third law because it implies that exactly the same magnitude of force acts on q 2.Coulomb's law is a vector equation and includes the ...
