Term
What do we do in order to describe the motion of n object in mathematical language?


Definition
In order to describe the motion of n object in mathematical language we have to introduce the model of the object, simplifying complicated situations. 


Term

Definition
The study of matter, motion, fores, and energy. It describes the motion of objects that are: 1. Large compared with the dimensions of atoms (10^10 m) 2. Moving at speeds that are low compared of the speed of light (c = 3x10^8 m/s) 


Term

Definition
Describing particles moving at any speed, even those whose speed approach the speed of light. 


Term

Definition
deals with heat, temperature, and the behavior of large numbers of particles. 


Term

Definition
Involves the theory of electricity, magnetism, and electromagnetic fields. 


Term

Definition
a theory dealing with the behavior of submicroscopic particles. 


Term

Definition
Anything you can measure or calculate in physics 


Term
What should you be concerned with in the study of mechanics? 

Definition
We should be concerned with physical quantities (units), these can be described in terms of three fundamental quantities: 1. Length (L); SI unit m 2. Time (T); SI unit s 3. Mass (M); SI unit kg 


Term

Definition
A scientific fact is a guess that has been tested over and over again and always found to be true. 


Term
