For those of you who want a bit of a challenge with vectors – here is a modelling and problem solving question that involves the concept of conservation of momentum mixed with vectors as well as conservation of kinetic energies. Must be okay with understanding the difference between vector and scalar quantities and finding the …
We show you how to add/subtract vectors in geogebra. We also show you how to multiply a vector by a scalar and then add/subtract another vector.
Today we show you how to draw vectors in Geogebra, either using the x and y components of a vector or using the magnitude and direction of a vector.
In this lesson we discuss how the distributive law works for the dot product.
In this lesson we talk about whether the associative law for real numbers works for vectors. The answer is it works for vector addition but not dot product.
In this lesson we talk about how vector addition and vector dot product is commutative. We also started making a summary table to compare commutativity between real numbers and vectors.
In this lesson we talk about how dot product is used to calculate how much work is done (in Physics). Work = force x distance.
In this lesson we discuss where the dot product comes from, how to calculate the dot product, given the length/maginitude of 2 vectors and the angle between them.
Prior to introducing you guys to the dot product, you must understand this concept of the scalar resolute – how much of one vector is acting in the direction of another vector.
In this lesson we’re going to talk about how the distributive law in algebra works with vectors (only with a scalar). Next lesson we will talk about the dot product.
