This module is part of a series of modules designed for teaching the physics component of GAME2302 Mathematical Applications for Game Development at Austin Community College in Austin, TX. (See GAME 2302-0100: Introduction for the first module in the course along with a description of the course,course resources, homework assignments, etc.)

The purpose of this module is to introduce motion and to explain displacement and vector analysis.

General background information

Bodies - not a reference to people

To begin with, physics textbooks often refer to something called bodies . By this, they are not referring to living bodies or the carcasses of once livingcreatures. Instead, they are referring to what people might ordinarily call objects.

For example, somewhere in this series of modules, we will discuss something call ed a free body diagram . A free body diagram can be drawn relative to any object, such as a child sitting motionless in a swing on the playgroundor a piano hanging on a rope.

Rest and motion

While nothing in the universe is truly motionless (at rest), some things around us such as buildings seem to be at rest, while other things such asplanes, trains, and busses appear to be in motion.

There is no such thing as absolute rest. However, two bodies moving together at the same rate (with reference to some third body) may be deemed to be at restrelative to one another.

Therefore, if you are standing motionless on the Earth, you are at rest relative to the Earth with reference to the Sun.

Kinematics and kinetics

The fundamental properties of motion are often referred to as kinematics .

According to the course description, in addition to "applications of mathematics and science" , the course is also to include "the utilization of matrix and vector operations, kinematics, and Newtonianprinciples in games and simulations" ,

The relationships between motion and force are often referred to as kinetics . These are the topics that will be covered in this and the next several modules in this collection.

Environment Heredity(I am not sure about heredity)
Helpful. .. thanks
Sure, anytime
I have other questions also
Based on the factors affecting learning, how do we improve learning
I think that addressing that everyone learns in their own time
Peer group influence can also be another reason
Also knowing what's going on at home. what pressure are the parents putting on them.
am I close or no
also is there a lack of care? going one more step. with peer groups do an activity that shows how much they have in common
I think one's society has a big role to play in determining what/when & how he/she learns.
multiple reasons at different stages. at the earliest stages of development in a child is behaviour of people around. A baby starts learning basic social expressions and actions by mimicking the people around it. further social and cultural practices enforces learning and behaviour
from need to nutrition everything affect development and learning when choosing on a single factor of influence it is necessary to keep these other factors in the mind as environment around people is very plastic and flexible and there are many variables playing active role
social interaction is surely a big influence hence can be used to improve learning.
to encourage learning it is important to establish curiosity and notion of possibility for more perspectives habit of questioning possibilities and cause and effect in a great way to encourage learning in my opinion. language is another important factor
under what schedule of reinforcement do animals learn from ?

I'm asking on behalf of someone How can a guy get over his weakness for girls? Like the person have soft spot for every girl and he thinks he love them then suddenly stuff change.... Like a switch

whats the age of the boy?
16 or 17
lol. it gets over with time. it's not something that can be changed instantly. and for teenagers.. anyone of opposite sex is a tasty lollipop.
yes in time it will go away but could also take years
maybe because he doesn't really have mind of making decisions at the moment on what he need and what he doesn't want
maybe he's trying to find someone to love because he's either lacked loved and feel that's the only way to feel loved or he's lonely and feels a girl can make it better . either he's got deal with the core issue
its natural. I think it should be like this. girls also have weakness toward guys. but you can overcome on few things like concept of beauty. first step is realisation which will grow in you. also discipline help in these things.
