Module 1:
Graduated cylinder
Formula/ Define momentum
Mass X velocity
Explain/ define gravity
An active force between two objects that depends on the mass and the distance between them
What is a machine
Device that changes work or increases motion from work
What is kinetic energy
energy through motion
Difference between independent vs dependent variables
Dependent variable relays on the experiment its the response to what was done. Independent variables are what you are changing to see how it affects the dependent.
What is speed
Distance an object travel in a certain amount of time
Distance/ Time
What is friction
The force that opposes the sliding motion of two surfaces touching each other.
define work
Force applied through distance
Applied force X distance
What is potential energy
Bonus
What are the three types we learned about
Energy stored
Chemical- energy stored through chemical bonds
Elastic- energy stored though bend, stretching or compressing an object
Gravitational- energy stored through gravity
What is the difference between Theory vs Law
Theory is an explanation based off gained information from observations. A law is a statement that seems to be also true.
What is velocity
Speed of an object plus its direction
how do you find weight
Mass X gravitational strength
Difference between a simple machine and a compound machine
A simple machine is a machine that is one one movement while a compound machine is a combination of one or more simple machines
Define energy
the ability to cause change
How do you find Density
Mass / volume
what is acceleration
Rate change in velocity
What are the newton's three laws
1) object in motion/ rest stays in motion/rest unless acted upoon
2) force is equal to mass X accleration
3) for every action is an equal and opposite reaction
Formula to find Mechanical advantages.
Output force / input force
What are the three types of heat transfer
Define each one
Conduction-through direct contact
Convection- density differences
radiation- waves
List the 6 steps of the scientific method
State the problem
Research
Form a hypothesis
Test the hypothesis
Analyze data
Draw conclusions
Formula for acceleration
(Final velocity- initial velocity) / time
1) pushing in same direction you add forces
2) Pushing at different forces in opposite direction you subtract
3) pushing different direction but same force its zero
Lever-seesaw
Axel and wheel-doorknob
Wedge- fork, knife, grater, peeler, hatchet
Incline plane-ramps
pulley-flag pole
screw- jar lid
Thermal energy is the total energy of particles within an object, heat to the movement of energy from one object to another, temperature is the average kinetic energy of particles within an object
