How to scientists communicate results?
By comparing data
What is science?
Science is a process of gathering information through observation and experimentation to ID patterns in the Natural world
When is something moving?
When the object changes it’s position relative to a reference point
Name the different ways an object can move
Straight line
Projectile
Circular
Vibrational
What is Miss. McConnell’s favorite ice cream flavor
Rocky Road
How can motion be described quantitatively?
Speed
Distance
Time
Acceleration
What is acceleration?
Rate of change of velocity
Formula for acceleration
Velocity final-Velocity initial
————————————
Time
What is a variable?
A quantity that can be specified with a numerical value and unit
What is a graph?
A mathematical tool displaying the relationships between variables
Steps to making a line graph
- Draw axis
- Label axes with independent and Dependent variables
- Create a scale
- Plot data
- ID relationships
- Fig# and title
How to calculate slope
Slope= y/x
What is the purpose of taking the average of many measurements?
To get precise and accurate data
What is force
A push or pull or any action that has the ability to change the motion if an object
What is the unit of measurement for force?
Newtons(N)
What happens when there is a balanced force?
No motion
What happens when there is an unbalanced force?
A change in motion
What is Newton’s first law?
An object in motion will stay in motion and an object at rest will stay in rest unless acted upon by an outside force
What is inertia?
Resistance an object must change in its state of motion.
+inertia=+mass
What is newtons second law of motion?
Force = mass • acceleration
F=MA
What is newtons third law of motion
For every action there is an equal and opposite reaction
What Is the unit of energy
Joule (J)
Formula for work
Newton•distance
What is energy
Ability to cause change
