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.
In this lesson we deal with a velocity problem using vectors.
In this lesson we discuss how to find a vector joining 2 vectors from the origin.
In this lesson we talk about a different kind of notation for vectors using angle brackets (not curly brackets because that would be specifying a point not a vector). We then talk about a quick way to find a vector joining any 2 points on the Cartesian plane.
In this lesson we talk about how to find the unit vector in the same direction as any vector expressed in terms of i and j.
In this video we solve a word problem involving vectors. Have a go at it to see whether you know everything we have done so far!
In this lesson we talk about how to find the x and y components of a vector given its magnitude and direction, by drawing a right angle triangle with the x axis and using trigonometry.
