Parallel circuits ensure that each component receives the same voltage, and they are widely used in electrical systems to ensure that the failure of one component does not affect the operation of others. On this page, we describe what parallel circuits are and give you an exercise to test what...

An object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an unbalanced force. Force equals mass times acceleration. For every action there is an equal and opposite reaction. Do you need to learn about Newton's first three...

We will look at the gravitational force acting on an object on a slope. These can be divided into two components, the normal (resisting) force pushing into the slope which produces friction and the shear or driving force pushing the block down the slope. So we must consider forces parallel...

Static equilibrium Structures that are stable are said to be in static equilibrium. This occurs when the sum of the forces on it in each direction is zero and the sum of the torques in each direction is zero. So there are two types of static equilibrium: translational equilibrium and...

Momentum is a vector quantity, so it is important to remember that direction must be taken into account when doing problems on momentum. Let's explore how we can do this. The moment p of an object is the product of its mass \(m\) and velocity \(v\), or: \[\begin{align*} p &...

Linear motion refers to the motion of an object in a straight line. Describing these motions require some technical terms such as displacement, distance, velocity, speed and acceleration. The terms and their relationships to one another are described in this module. Scalar and vector quantities Quantities that have only a...

Series circuits are electrical circuits in which components are connected end-to-end such that the same current flows through each component sequentially. On this page, you will find out about Kirchoff's laws and two ways of connecting circuits. Kirchoff's laws The principle of conservation of charge and the principle of conservation...

Introducing the basic concept of vectors (which are measurable quantities with direction such as force) and the concept of a scalar (which is a quantity without a direction such as heat or thermal energy). We cover vector components (aligned along the horizontal and vertical or the 3-dimensional axes), unit vectors...

The shortest distance from any point in the air to the ground is defined by a line sitting at right angles to the ground going straight down. Learn how to find the perpendicular (right angle) distance from a point to a plane. What do we mean when we talk about...

If you are on the side of a hill, the gradient depends on the direction you look. So the directional derivative is the gradient in a particular direction. (See also Linear graphs) Learn how to find the directional derivative of a function of two variables f(x,y) or three variables g(x,y,z)...
-
Vector quantities in combination will enhance or counteract each other, depending on their direction. An opposing force for example will lessen another force. However, if the forces (or vector quantities) do not act along exactly the same line, it is difficult to know how they will interact. This task is...

What is a scalar product? What is a dot product? This is the result of multiplying the magnitudes of the components of two or more vectors. The result is not a vector, but a scalar (which is without direction). There are two ways to multiply two vectors: The scalar or...

What is a vector product? What is a cross product? The vector product is a vector that is the result of multiplying the magnitudes (size) of two vectors. The magnitude is found using matrices and determinants). The result of the cross product is another vector, and the direction is perpendicular...

Two 2-dimensional planes will slice through each other (unless they are parallel). Where they slice will be defined by a straight line. There will also be an angle between the two planes.
