force
A push or pull upon an object resulting from the object's interaction with another object.
Vector Quantity
The Physical quantity that has both directions as well as magnitude
Magnitude
Represents the strength and the Direction of the force exerted.
balanced force
when 2 forces act on an object that is equal in size but are opposite in direction, we say the forces are?
unbalanced Force
when 2 forces are acting on an object and are not equal in size, we say the forces are?
Net Force
overall force acting on an object or a combination of the magnitude and the direction
Aristotle
He made pioneering contributions to all fields of philosophy and science, he invented the field of formal logic, and he identified the various scientific disciplines and explored their relationships to each other. He was also a teacher and founded his own school in Athens, known as the Lyceum.
Galileo Galilei
He used an Archimedean model of floating bodies, and later the balance, argues that there is only one principle of motionā€”heaviness. Bodies move upward not because they have a natural lightness, he says, but because they are displaced or extruded by other heavier bodies moving downward.
Isaac Newton
is popularly remembered as the man who saw an apple fall from a tree, and was inspired to invent the theory of gravity. If you have grappled with elementary physics then you know that he invented calculus and the three laws of motion upon which all of mechanics is based.
Law of Inertia
An object will not change its motion unless a force acts on it. What law of motion is this? (name of law not number,Add "Law of")
Mass
Less inertia has less?
Friction
Force present on the surface in contact with the object that tends to oppose the force acting on a body
Law of Acceleration
a quantitative description of the changes a force can produce in the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. ( NAME OF LAW NOT NUMBER, ADD" LAW OF")
a= F/m
What is the formula to find Acceleration? (Use parentheses "(a)" for multiplication, And the slash sign "/" for division)
F=(m)(a)
What is the formula to find Force? (Use parentheses "(F)" for multiplication, And the slash sign "/" for division)
m=F/a
What is the formula to find mass? (Use parentheses "(F)" for multiplication, And the slash sign "/" for division)
acceleration
m/s^2 is the unit sign of?
Force
N is the unit sign of?
Mass
Kg/g is the unit of?
Law of Action and Reaction
for every action (force) in nature, there is an equal and opposite reaction ( NAME OF LAW NOT NUMBER, ADD" LAW OF")
Beaker
are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations.
Laboratory Equipment
The type of equipment found in buildings or rooms equipped for conducting scientific research or teaching practical science and for conducting scientific experiments and research.
Bunsen burner
is a type of gas burner commonly used as a heat source in the laboratatory
Burets
are for addition of a precise volume of liquid. The volume of liquid added can be determined to the nearest 0.01 mL with practice.
Clay Triangles
are placed on a ring attached to a ring stand as a support for a funnel, crucible, or evaporating dish.
Droppers and disposable pipets
are for addition of liquids drop by drop.
erlenmeyer flask
are useful to contain reactions or to hold liquid samples. They are also useful to catch filtrates.
Glass Funnel
are for funneling liquids from one container to another or for filtering when equipped with filter paper
graduated cylinder
are for measurement of an amount of liquid.
Ring stand with Rings
are for holding pieces of glassware in place.
Test Tubes
are for holding small samples or for containing small scale reactions.
Test tube holder
are for holding test tubes when tubes should not be touched
Tongs
Similar in function to forceps but are useful for larger items.
Volumetric Flask
Used to measure precise volumes of liquid or to make precise dilutions.
Wash Bottle
Used for dispensing small quantities of distilled water.
Watch glasses
are for holding small samples or for covering beakers or evaporating dishes.
Wire Gauze
on a ring supports beakers to be heated by Bunsen burners
thermometer
is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air
alcohol lamp
is used for heating, sterilization, and combustion in a laboratory.
microscope
is an instrument that can be used to observe small objects, even cells.
Work
is the product of the force applied and the displacement; it is based also if the object is moving on the direction of the force applied.
W=(F)(m)
What is the formula to find work? (Use parentheses "(a)" for multiplication, And the slash sign "/" for division)
J
What is the unit for work?( letter only)
No work done
If there is no force applied, there will be no movement and direction of the movement, therefore there is?
No work done
If there is a force applied but the object did not move, there will be no direction of the movement, therefore, there is still?
No work Done
If there is a force applied, and the object moved, but the direction of the movement is not the same as the direction of the force applied, there is still?
Work done
If there is a force applied, and the object moved, but in the not exact direction of the force applied, there is?
Work Done
If there is a force applied, and the object moved, and in the exact direction of the force applied, there is?
1J
1,000,000 mJ is how many Joules?(add Unit sign)
J=(1,000,000)(mJ)
What is the formula of mJ to J? (Use parentheses "(a)" for multiplication, And the slash sign "/" for division)
mJ= 1,000,000/J
What is the formula of J to mJ? (Use parentheses "(a)" for multiplication, And the slash sign "/" for division)
James Watt
A Scottish inventor where developed the concept of horsepower. The SI unit of power, watt, was named after him. Watt became interested in the technology of steam engines.
Power
is the rate at which work is done and which energy is transferred
W
WHAT is the unit sign of Power? (Letter only)
Power= Work done/ Time = energy transferred/ time
What is the formula to find power?(Use parentheses "(a)" for multiplication, And the slash sign "/" for division)
