Properties | are the qualities or attributes that, taken together, are usually peculiar to an object. |
Measurement | a comparison. a process of comparing a property to a well-defined and agreed-upon referent. The well-defined and agreed-upon referent is a standard called a unit. |
The most two common systems of units are: | The English System and the Metric System (Le Systeme International d' Unites) or SI. |
Length | Metric Unit: meter Symbol: m |
Mass | Metric Unit: kilogrm Symbol: kg |
Time | Metric Unit: second Symbol: s |
Current | Metric Unit: Ampere Symbol: A |
Temperature | Metric Unit: Kelvin Symbol: K |
Amount of Subsance | Metric Unit: Mole Symbol: mol |
Luminous Intensity | Metric Unit: Candela Symbol: cd |
4 Fundamental Properties of the Metric System | Length, Mass, Time, Charge |
The standard unit of Length | meter |
The standard unit of Mass | kilogram |
The standard unit of Time | second |
The value of a second is based off of the vibrations of | the cesium-133 atom |
speed | change in position over change in time d/t distance/time |
velocity | change in position over change in time df - di/tf - ti |
acceleration | change in velocity over change in time vf - vi/tf - ti |
If the acceleration is in the direction of motion it is | positive |
If the acceleration is in the opposite direction of motion it is | negative |
average speed | distance/time m/s |
average velocity | change in position/change in time m/s |
acceleration | change i velocity/change in time m/s2 |
find vf | vi + at |
find vf2 | vi2 + 2ax |
find x | vit + 1/2at2 |
acceleration due to gravity (g) | 9.8m/s2 |
Inertia | an object's tendency to resist changes in it's motion. |
Newton's Laws of Motion | 1 - Inertia 2 - Related Force to Acceleration 3 - Action - Reaction |
Four Fundamental Forces | 1- gravitational 2- electromagnetic 3- strong nuclear 4 - weak nuclear |
1 Newton | 1kg x m/s2 |
Weight (W) | measure of the force of gravity on a mass. Measured in Newtons |
Normal Force (N) | always perpendicular to a surface, surface pushing back, electromagnetic force in nature |
