What is Physics?

• Physics is the science of how matter and energy interact

  
  

• physics covers various physical interactions and phenomena that occur in the real world. 

• Examples; Transportation,Texting,Gaming,etc

8,059,000

• 3

• 4

• 7

• 6

Vectors & Scalars

• Scalars are quantities that are described by magnitude alone

• magnitude means amount or quantity

• How far, how strong, how much?

• Vectors are quantities that are magnitude and direction

• needs to be calculated to determine

Scientific Method

• a methodical way to test a hypothesis, based on data collection and controlled variables.is

• Hypothesis is an educated guess

• Independent variable a variable that is changed in an experiment.

• Dependent variable a variable that changes in response to the independent variable changes.
