Unit of power
A simple machine and ramp
A gear ration
Work input is used to describe what type of machine?
The ratio of output force to input force of a simple machine is called ?
The ratio of useful work output to total work input is called?
The unit used for force is what?
The metric unit for work is?
Power is measured in what unit?
A set of rules that is based upon recurring facts that have been carefully documented
This helps people communicate amounts of things
This shows how two variables are related
An educated guess that predicts the relationship between the independent and the dependent variables in the expiriment
What is the equation for speed?
What is the equation for distance?
This system is easily used because it is based on factors of 10
This changes according to where you are at in the universe
Units for velocity
The slowing down of an object
Newtons 2nd law formula
Units for acceleration
An object at rest will stay at rest or an object in motion will stay in motion with the same speed and direction
Newtons 1st law
Acceleration due to gravity
9.8 m/sec squared
A force that gives 1kg mass an acceleration of 1 m/sec squared
The force of gravity is balanced by the air resistance of an object
A device with moving parts that work together to accomplish a task
Includes everything you do to make the machine work
What the machine does for you
A machine is the ratio of the output force to the input force
The force that results from relative motion between objects
Stored energy that comes from position
Energy from motion
The total momentum in a system of interacting objects cannot change as long as all forces act only between the objects in the system
Law of the Conservation of Momentum
One of these is the energy needed to push with a force of one newton over a distance of one meter
The law states that energy can never be created or detroyed just converted from one form into another
Law of Conservation of Energy
Objects that change shape or stick together. Energy is not destroyed but it is transformed into forms
For every action force, there is a reaction force equal in strength and oppostire in direction
Newtons 3rd law
Measures a moving objects resistance to changes in its motion p=mv
A change in momentum created by a force exerted over time
Occurs when objects collide so that the total kinetic energy remains the same before and after the collison
A fundamental quantity of the universe; measure of ability to change or create change
A form of energy fxd
A factor that affects the behavior of a system
Anything that has mass and takes up space
A carefully designed test done under controlled conditions
Measures the amount of matter that makes up an object
This system of measurment uses feet
Distance something traveled by the time it took to travel that far
This type of variable is kept the same in the expiriment
What variable is placed on the y-axis
The detailed explanation of the results of an expiriment
The independent variable goes on which axis
