Projectile Motion
This lesson covers the definition of projectile and projectile motion. It explains the concepts of time of flight, maximum height, and range, along with the relevant equations and examples from sports and warfare.
- 15:21 “The range, the range, the range, bearing the mind that R equal to U squared sin 2 theta over G, then by inserting the parameters, we have R is 200 squared times sin 2 theta means 2 times the angle of projection, which is...”
- 16:15 “you can go about a projector or motion. Like number one, a body is projected upwards with an initial speed of 400 meters per second at an angle of 30 degrees, find about one time of flight to horizontal distance traveled...”
- 11:17 “over G. So these are formula for the range of projectile. Yeah, so R equal to U squared sin 2 theta over G. When theta is 45 degrees, we say that range is maximum. At 45 degrees, our range is maximum. So 2 theta, that's...”
Measures of Central Tendency
This lesson covers the measures of central tendency, including mean, median, and mode. Students will learn how to calculate the median, find the mode, calculate the mean, and determine the range of a given data set. The lesson emphasizes the application of these measures in analyzing data.
- 18:58 “my median? My median, before you get your median, the first thing to do is to, we have, we've rearranged it, you count, one, two, three, four, five, six, seven. So, it could easily be divided into three. So, I'll have th...”
- 20:34 “of the value, highest minus lowest. So, when I have this behind, so it's a goal. Now, if you look at the first set of data, what's the lowest? The lowest my range would give me the lowest here, the highest in this set of...”
- 19:47 “is another way of summarizing what is set of data tells us. A measure of spread tells us how spread, spread out the data are. For example, there are the two set of data that we have here. How are these data spread out? T...”
