average speed -ANSWER distance an object travels divided by the time the object travels
without regard to direction of travel
average speed equation -ANSWER average speed (Vav) = distance/time = d/t
velocity -ANSWER speed in a specific direction
scalar quantity -ANSWER quantity described simply by a numeric value e.g., speed
speed -ANSWER expressed in units of magnitude
vector quantity -ANSWER quantity describing the time rate of change of an object's
position e.g., velocity which must be expressed in both units of magnitude and direction
of motion
average velocity -ANSWER determined by averaging the initial speed and the final speed
of the object (add the two together and divide by 2)
average velocity equation -ANSWER Vav = (Vf + Vi)/2
Vav= average velocity
Vf= final velocity
Vi= initial velocity
acceleration -ANSWER rate of change in velocity over a period of time, it is a vector
quantity and is expressed in terms of magnitude and direction
acceleration equation -ANSWER a = (Vf - Vi)/change in t
a= acceleration
Vf= final velocity
Vi= initial velocity
t= time
gravity -ANSWER accelerates an object released above the earth's surface rate of
9.8m/s^2
projectile motion -ANSWER possible for an object to display two types of motions
simultaneously. can be kicked form a ledge and fall, which causes it to move
horizontally at the same time it falls toward Earth.
, horizontal distance (dx) -ANSWER dx = (Vx)t
Vx= velocity
t= time
x subscript= denote motion along the horizontal plane (x axis)
vertical motion -ANSWER Vf^2 = Vi +2ad
d=((1/2)at^2) + (Vi)t
Vf= Vi + at
Vf= final velocity
Vi= initial velocity
a= acceleration
d= distance
t= time
force -ANSWER push or pull on an object
net force -ANSWER the sum of the individual forces acting on an object
true or false: when two forces are equal in magnitude and in opposing directions they
cancel each other out and result in a balanced force -ANSWER true, however if one of
the two forces are greater than the other, an unbalanced force exists and with it
acceleration
+ and - signs are used -ANSWER to indicate direction of force
newton's first law of motion -ANSWER a body at rest will remain at rest, and a body in
motion will remain in motion with a constant velocity, unless acted upon by an
unbalanced force
newton's second law of motion -ANSWER an unbalanced force will cause acceleration,
and this acceleration is directly proportional to the unbalanced force.
F=force
a= acceleration
k= the constant of proportionality = mass of object
F = ma
newton (N) -ANSWER unit of force
weight (W) -ANSWER W = mg
m= mass (in kilograms)
g= 9.8 m/s^2
newton's third law of motion -ANSWER for every action there must be an equal and
opposite reaction
