# Physics for exam

### First Exam

Change in position over time Motion
what you are comparing motion to Frame of Reference
states where the zero point is and the direction the value increases Coordinate System
same distance traveled each second (faster it goes, steeper the slope) Constant Speed
Series of points which represents position over equal intervals of time Motion Diagram
the length between 2 points distance
magnitude- no direction (ex. distance) Scalar quantity
distance and direction displacement
Magnitue and direction (ex. displacement) vector quantity
At a constant velocity average velocity equals the ___________ ___________ instantaneous velocity
Displacement- with constant acceleration d=1/2(Vf+Vi)t
maximum speed that a falling object can reach terminal velocity
time it takes to go up and go down are the ____ if it is thrown and caught at the same velocity. same
an object shot in the air projectile
path an object takes trajectory
When an object is moving in ______ motion it has a constant velocity horizontal
When an object is moving in _______ motion, gravity caues it to accelerate at 9.8m/s/s Vertical
Horizontal motion and vertical motion are _____ of each other independent
How does the acceleration due to gravity affect the velocity of a falling object?
sum of all forces acting on an object net force
when fnet=0, no accleration and the object is either at rest or moving t a constant velocity the object it in ________ equilibrium
the force that is perpendicular to the surface, magnitude is equal to gravity normal force
the force an object expereinces as a result of all the forces acting on it apparent weight
a push or pull exerted on an object force
Newton's second law the acceleration of an object is equal to the sum of the forces acting on the object, divided by the mass of the object
Newton's first law an object that is at rest will remain at rest, and an object that is moving will continue to move in a straight line with constant speed, if and only if the new force acting on that object is zero.
the tendency of an object to resist change inertia
the force exerted by a fluid on the object moving through the fluid. drag force
Newton's Third Law all forces come in pairs
a force exerted by a string or rope tension
