motion the state in which one objects distance from another is
changing.
reference point a place of object used for comparison to
determine if something is in motion
speed the distance an object travels per unit of time
velocity a speed in any direction
a
Exothermic reactions a chemical reaction in which heat is
released to the surroundings
Mole Ratio The relative number of moles of the substances
required to produce a given amount of product in a chemical
reaction.
Oxidation Reduction Reaction any chemica
Force A push or a pull
Equilibrium when the net force on an object is zero
Newton's 1st Law An object at rest remains at rest; and if in
motion will remain in motion in a straight line; unless a force acts
on it
Gravity This acts on a mass to create the f
Mass An objects inertia depends on the amount of its
Acceleration The rate at which velocity is changing
Vector quantity Force, velocity, acceleration have both magnitude
and direction so are
Speed distance travelled divided by time taken
Free fall when t
unbalanced force forces that produce a nonzero net force
net force the overall force an an object
friction the force between two rubbing surfaces
gravity the force that pulls objects towards each other
free fall when the only force acting on an object is
Alpha particle Is a positively charged atom that is released in
the disintegration of radioactive elements and that consists of two
protons and two neutrons
Background Radiation The nuclear radiation that arises
naturally from cosmic rays and from radioac
Acids Any compound that increases the number of hydronium
ions when it dissolves in water. Starts with an H
Antacid a weak base that neutralizes stomach acid.

Catalyst A substance that changes the rate of reaction with out
being consumed or changed significantly.
Combustion Reaction The oxidation reaction of an organic
compound, in which heat is released.

Newton's Third law for every action there is an equal and opposite
reaction
Centripetal Force a force that causes an object to move in a cycle
energy (physics) the capacity of a physical system to do work
kinetic energy the mechanical energy that a body h
What are units for C that will make this equation unitically correct?
V= Cxat
m/s = C [m] [m/s] [s]
m/s = C [m2/s]
1/m = C
What are units for D & Z that will make this equation unitically correct?
X = D v2 t2 + Z a v t2
M = D [m2/s2] [s2]
M = D m2
1/m = D
CALCULATIONS
Percentage error= E-K divided by K and then x by 100
Absolute Error = (exp) (analytical)
Discussion:
We were able to figure out the resultant vector by vector addition with two applied forces. The
