|
|
Mechanical Equilibrium |
A state of matter where no physical changes occur |
|
|
|
Equilibrium |
multiple things in balance together |
|
|
|
Force |
Push or pull |
The group arguing |
|
|
Vector |
An arrow which represents magnitude and direction of a certain quantity |
The map of Terminus |
|
|
Net Force |
All forces acting together on an object, which depends on the magnitudes and directions of the applied forces |
The group working together to get to Terminus |
|
|
Scalar Quantity |
Magnitude only, no direction. For example, time, area, and volume are scalar quantities |
|
|
|
Tension |
A stretched string is under a "stretching force" Tension acts opposite to weight and gravity. |
|
|
|
Resultant |
A sum of two vectors |
|
|
|
Normal Force |
The upward force that balances the weight of an object on a surface |
|
|
|
Friction |
A contact force between objects that slide or tend to slide against each other |
Glenn and Maggie <3 |
|
|
Static Equilibrium |
Objects at rest |
Bob, Beth, Lizzie, Meeka, and basically everyone who has died :( |
|
|
Dynamic Equilibrium |
Objects moving at a constant speed in a straight- line or path |
The road to Terminus |
|
|
Free Body Diagram |
A image showing all forces acting on an object with vectors |
The map of Terminus |
|
|
Inertia |
The property of a body to resist changes to its state of motion |
The group surviving the winter |
|
|
Newton's 1st Law |
Inertia |
|
|
|
Mass |
roughly the amount of material present in the object -Mass is not weight |
|
|
|
Weight |
A measure of gravitational force acting on the object |
Walkers falling into a hole |
|
|
Newton |
- The SI unit force is the newton. The SI symbol for the newton is N. - One newton is equal to slightly less than a quarter of a pound |
|
|
|
Law of Inertia |
Every object continues in a state of rest, or of uniform speed in a straight line, unless acted on by a nonzero net force. |
|
|
|
Speed |
- Can calculate by dividing the distance traveled by time - how fast an object is moving |
How fast the group can run from the walkers |
|
|
Instantaneous Speed |
A speed at any instant |
The speed of the walkers |
|
|
Average Speed |
The total distance covered divided by the time |
Total distance from Terminus |
|
|
Velocity |
How fast and in what direction it moves |
Abraham's tank |
|
|
Acceleration |
- Can be found by dividing the change in its velocity by time -The rate at which the velocity is changing |
|
|
|
Inversely |
The two values change in opposite direction. As the denominator increases, the whole quantity decrease by the same factor |
|
|
|
Newton's Second Law |
States the acceleration produced by a net force on an object is directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of the object. |
|
|
|
Fluids |
- Liquids and gases that flow - occurs as an object pushes aside the fluid it's moving through |
|
|
|
Air resistance |
The friction acting against something in the air
|
|
|
|
Free Fall |
An object moving under gravitational force |
|
|
|
Elapsed Time |
The time that has passed since the beginning of motion like a fall |
|
|
|
Interaction |
A mutual action is an interaction between one thing and another |
|
|
|
Newton's Third Law |
For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. |
|
|
|
Action Force |
A force acting against the reaction force |
|
|
|
Reaction Force |
A force against action force and always need each other. |
|
|
|
Momentum |
- inertia in motion - The mass of an object multiplied by its velocity - Momentum = mass * velocity - p = mv |
|
|
|
Impulse |
The quantity of force * time interval is called impulse - Impulse = F * t - The greater the impulse the greater the change in momentum - Impulse = change in momentum or F*t = /\ (mv) |
|
|
|
Law of Conservation of Momentum |
states that in the absence of an external force, the momentum of a system remains unchanged |
|
|
|
Law of Universal Gravitation |
Every object attracts every other with a force |
|
|
|
Universal gravitational constant |
- 6.67 * 10 ^ -11 - N*m^2/kg^2 - Describes the strength of gravity |
|
|
|
Center of gravity |
The point where gravity reacts |
|
|
|
Center of Mass |
The average position of mass in an object |
|
|
|
Joule |
Unit of work is the newton-meter |
|
|
|
Work |
when a net force acts on an object and the object moves in the directon of the net force |
|
|
|
Power |
power is the rate of doing work. It is equivalent to an amount of energy consumed per unit time. - work/ time |
|
|
|
Watt |
A watt is the unit of measure for calculating the power of a circuit. A single watt (W) is equivalent to one joule (J) per second (S), where a joule is a measurement of the energy. |
