Flashcards in Newtons Notions Vocabulary Deck (27):
1

Any of the basic mechanical devices for applying a force such as an inclined plane wedge or lever

Simple machines

2

A rigid bar resting on a pivot used to help move a heavy or firmly fixed load with one end when pressure is applied to the other

Lever

3

A piece of wood metal or some other material having one thick edge that is driven between two objects of parts of an object to secure or separate them

Wedge

4

A short slender sharp pointed metal pin with a raised helical thread running around it and a slotted head used to join things together by being rotated so that it pierces wood or other material and is held tightly in place

Screw

5

A sloping ramp up which heavy loads can be raised by ropes or chains

Inclined plane

6

A wheel with a grooved rim around which a cord passes it acts to change the direction or a force applied to the cord and is chiefly used to raise heavy weights

Pulley

7

A simple lifting machine consisting of a rope that unwinds from a wheel onto a cylindrical drum or shaft joined to the wheel to provide mechanical advantage

Wheel and axle

8

The point on which a lever rests or is supported and in which it pivots

Fulcrum

9

States that an object will remain at rest or in uniform motion in a strait line unless acted upon by an external force

Newtons 1st law

10

States that the acceleration of an objects is dependent upon two variables the net force acting upon the object and the mass of the object

Newtons 2nd law

11

For every action there is an equal and opposite reaction

Newtons 3rd law

12

Two forces acting in opposite directions on an object and equal in size anytime there is a balanced force on an object object stay still or continues moving continues to move at the same speed and in the same direction

Balanced forces

13

If two individual forces are equal in magnitude and opposite direction in the forces are said to be balanced and object is said to be acted upon by an unbalanced force only when there is an individual force that is knocking down spy a force of equal magnitude and in the opposite direction

Unbalanced force

14

Definition of inertial force A force opposite indirection to an accelerating force acting on the body and equal to the product of the Excelerator in force and the mass of the body

Inertia

15

The resistance that one surface or object encounters with moving over another

Friction

16

The speed of something in a given direction

Velocity

17

The rate at which someone or something is able to move or operate

Speed

18

The force that attracts a body toward the center of the earth or toward any other physical body having a mass for most purposes newtons laws of gravity apply with minor modifications to take the general Siri of relativity into account

Gravity

19

A coherent it typically large body of matter with no definite shape

Mass

20

The action or process of moving or being moved

Motion

21

Energy that a body possesses by virtue of being in motion

Kinetic energy

22

The energy possessed by a body by virtue of its position relative to others stresses with in itself electric charge and other factors

Potential energy

23

Activity involving mental or physical effort done in order to achieve a purpose or result

Work

24

Increase in the rate or speed of something

Acceleration

25

The overall force acting on an object

Net force

26

The constant speed that are freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration

Terminal velocity

27

The quantity of motion of a moving body measured as a product of its mass and velocity

Momentum
