Force
the measure of how hard gravity pulls down an object
Weight
The application of a force to an object to move it a certain distance in the direction of the force.
Work
Made up of a bar that pivots at a fixed point
Lever
work is easier not only by changing the direction of the force, but also by multiplying the effort
Double pulleys
What is the three law of motion
Law of Inertia, the law of acceleration, the law of action and reaction
The measure of the amount of matter an object contains
Mass
An amount that an object travels
Distance
The fulcrum is in the middle, load and force on the ends
First class lever
Work is easier by changing the direction of the effort force
Single pulley
3 types of forces
Gravitational, applied, and frictional force
A push or pull action upon an object as a result of its interaction with another object.
Force
Straight slanted surface
Inclined plane
The load (resistance) is in the middle, force and fulcrum are on the ends
Second class lever
A simple machine that consists of two circular objects of different sizes
Wheel and axle
Six basic types of simple machines
Inclined plane, wedge, screw, lever, pulleys, wheel and axle
the force which the earth, moon, or other massively large object attracts another object towards itself.
Gravitational force
An inclined plane that is wider or thicker at one end than at the other
Wedge
The force (effort) is in the middle, the load and fulcrum are on the ends.
Third class lever
2 examples of wedge
Knife blade and axe
Two types of pulley
Single and double pulley
A force that is applied to an object by a person or another object.
Applied force
An inclined plane that is wrapped around a cylinder
Screw
A rope or chain wrapped around a wheel
Pulleys
two examples of screw
screw and battle cap
One example of contact force
Muscular, frictional
