Question  Answer 
Distance  The amount of space between two points. 
Origin  The starting point or reference point in which positions are described from. 
Position  The current location of an object according to the origin or starting point. 
Coordinates  The negative or positive numbers on geographic points used to describe a position 
Speed  The distance an object travels divided by the time it takes. 
Constant Speed  The speed of an object that travels the same distance every time unit or interval 
Average Speed  The total distance divided by the total time 
Velocity  The speed (the distance traveled over a period of time) with a specific direction. 
Slope  A line made by the points on a graph 
What is the formula for Speed?  Distance divided by Time d/t 
What is the formula for Distance?  Speed times Time s x t 
What is the formula for Time?  Distance divided by Speed d/s 
Force  (F) an action (push/pull) that has the ability to change motion. 
Friction  (f) a force that resists forward motion 
Vector  A quantity that includes SIZE and direction 
Magnitude  Describes the size of a vector 
Net Force  (Fnet) the sum of all known forces on an object 
Balanced Forces  When the sum of an object's forces are equal to zero. 
Equilibrium  a STATE of balance forces or when forces=0 
Normal Force  (Fn) a force that a surface exerts on an object that is pressing on it 
Tension  A pulling force that acts in a string, rope, or other object. 
Compression  A squeezing force that can act on a spring 
What are the types of Forces?  Friction Nuclear Electromagnetic Gravitational 
What are the types of Friction?  Static Rolling Sliding Air Resistance Viscous 
What forces on present on a free body diagram/force diagram  Normal Force, Forward Force, Friction, Gravitational Force 
Where are the forces located on the Free Body Diagram/Force Diagram  Normal Force(top), Forward Force(right), Friction(left), Gravitational Force(bottom) 
Which forces on the Free Body Diagram/Force Diagram are Positive and Negative?  Normal Force, Forward Force are positive and Gravitational Force, Friction are negative 
Inertia  A property of matter that an object has that resists a change in motion. More Mass=More Inertia Bowling Ball&Golf Ball, Bowling Ball is harder to push, because more INERTIA 
Unbalanced Forces  A net force result that shows a change in motion; can be (+) or () Basically the object is moving 
Acceleration  The rate that speed changes over time 
Freefall  The motion of an object only acted on by the force of gravity; air resistance has little to no effect. 
What is Newton's 1st Law?  An object at rest, will stay at rest, until an outside force changes its state. (Same with an object in motion) 
What is Newton's 2nd Law?  Force causes acceleration, but mass resists acceleration (slows it down). Proves F=mxa formula 
What is Newtons 3rd Law?  For every action, there is an equal and opposite reaction. 
What is the FIRST acceleration Formula?  Magic Triangle. F=mxa M=f/a A=f/m 
What is the SECOND acceleration formula?  Speed2Speed1  Time 
Static Friction  No object movement 
Sliding Friction  Friction that is applied to moving objects 
Rolling Friction  Friction applied to rolling objects 
Air Resistance Friction  The friction of motion through air 
Viscous Friction  Friction with movement in liquids 
Nuclear Force  The force that holds atoms together 
Electromagnetic Force  force between positively charged and negatively charged objects 
Gravitational Force  Force of attraction due to great distances in mass and difference
