Welcome to my Physics class today we are going to learn about Newton's laws. What is your guys names
Mrs.Krab's classroom
My name is Luke
My name is Mary
Do you know what the first Newton's law
Mrs.Krab's classroom
ummm
The first law is objects at rest remain at rest and objects in motion remain in motion in a straight line unless acted upon by an unbalanced force
Do you guys know what the second and third law is
Mrs.Krab's classroom
The second one is force equals mass times acceleration
The third one is for every action there is an equal and opposite reaction
Welcome to my Physics class today we are going to learn our vocab words. What is your guys names
physics: is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact.
Science: is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.

these are our vocab words Physics, Science, Theory, Observation, Inference, Hypothesis, Independent variable and Dependent variable
Theory: traditionally refers, somewhat vaguely, to a given set of notions and rules, usually formulated in the language of mathematics, that describe how some physical system or class of physical systems behaves.
Observation: can also involve the perception and recording of data via the use of scientific instruments
Mrs.Krab's classroom
Inference: a conclusion reached on the basis of evidence and reasoning.
Nice job you guys got them all right
Independent variable: is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable.
Mrs.Krab's classroom
Dependent variable: is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable
Hypothesis: a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
