Science Flashcards
science
Distance an object moves over given amount of time
Velocity
Mass and velocity
Momentum
First that works against the effort of force
Resistance force
Unit to measure force
Newton
An object that makes work easier
Machine
The point on which lever turns
Fulcrum
The change in velocity during a period of time
Acceleration
Pull of one object on another
Gravity
Change of an object’s position
Motion
A type of simple machine a bar that turns on a fulcrum
Lever
Unit to measure work
Joule
The Force applied to simple machine
Effort force
Occurs when the force moves an object over a distance
Work
The force that resists the movement of objects against each other
Friction
Amount of space traveled from where an object starts to where it is
Distance
Of simple machine consisting of a wheel with a chain or rope wrapped in the groove of the wheel
pulley
Resistance to change in motion
Inertia
A simple machine a flat Slanted surface such as a ramp
Inclined plane
Ray at which an object travels
Speed
Of simple machine consisting of an incomplete that is wound around the cylinder or cone
A screw
A machine combines two or more simple machines
Compound machine
A type of simple machine consisting of two inclined planes back to back
Wedge
Of simple machine consisting of a wheel and a rod running through the wheel
wheel and axle
To lower and raise very heavy objects
Lever
To move objects along an incline surface
Ramp
The decrease and effort needed to move an object
Mechanical advantage
To move things along the ground
Wheel
To lift a lower objects more easily
Pulley
To break something apart
Wedge
To hold something in place
Screw
Body at rest will stay at rest but a body in motion will stay in motion unless it is acted upon by external force
1st law
A force acting to an object is equal to the mass of that object times acceleration,
f = MA
2nd law
For every action there is an equal opposite reaction.
3rd law
