1-D Forces, Newton's Laws

        Help!  

Term
Definition
Inertia   An object's ability to resist change in its state of motion  
🗑
Force   A push or pull or another outside affect that acts on an object. Equation- F=ma Unit - kgm/s/s = Newtons, N  
🗑
Friction   A non-conservative force that acts in the opposite direction of the objects motion. Friction always reduces Net Force.  
🗑
Momentum   An object's ability to resist change in motion. Object's have momentum only when they are moving.  
🗑
Mass   How much matter an object contains. *The total number of atoms an object has. This does not change based upon location.  
🗑
Weight   An object's force due to gravity. The object's mass x gravity. This changes depending upon the location of an object.  
🗑
Gravity   A form of acceleration based upon the MASS of an object. Acceleration due to gravity on Earth = -9.8m/s/s.  
🗑
Newton's 1st Law   **Known as the Law of INERTIA** An object will maintain its state of motion unless an outside net force acts on the object.  
🗑
Newton's 2nd Law   **Known as the Law of PROPORTIONS** An object's acceleration is directly proportional to the force acting on the object and inversely proportional to the mass of the object. As MASS inc. ACCELERATION decr. As FORCE inc. ACCELERATION inc.  
🗑
Newton's 3rd Law   **Known as the ACTION/REACTION** For every force there is another force equal in magnitude and opposite in direction. **ONE OBJECT MAY NOT EXERT ANY MORE FORCE THAN ANOTHER OBJECT CAN WITHSTAND**  
🗑
Static Equilibrium   Net Forces on an object are = 0, zero Newtons AND the object is at rest.  
🗑
Dynamic Equilibrium   Net Force on an object are = 0, zero Newtons AND the object is in motion. **Think cruise control**  
🗑
Collisions   When two or more objects interact with one another exerting equal forces upon one another.  
🗑
Net Forces   The addition of all forces acting on an object. Generally done in one dimension. Equation: ∑F= F1 + F2 + Fn Unit: N, Newtons  
🗑
Conservation of Momentum and Energy   Interactions with objects will result in momentum and energy being conserved within a system. Energy and momentum may be lost by individual objects but the conservation can be tracked within the system.  
🗑
Free Fall   An object moving in the Y-Axis falls without any opposing force as it falls. NO FRICTION.  
🗑
Free Body Diagrams   An image that outlines and describes all the forces acting on a system. Fn= Force Normal/support force (Always up) W = weight (Always down) m*g Fg= Force due to gravity Ff= Force of friction Fdrag = Force of air resistance Fa = Force applied  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
