Temperature
What temperature does water freeze in Fahrenheit?
32 ° F
What does the variable 'vf' stand for?
(a) Final Vector
(b) Final Velocity
(c) Final Vibration
(d)Final Velcro
(b) Final Velocity
The final velocity, or also know as just 'v', is the end velocity in that portion of the problem.
Ex: a ball starts at rest and is then is kicked, and it passes the goal line at a speed of 12m/s.
vf=12 m/s
What is the distance to the center of the circle called?
What is an S.I unit? (or International System of Units)
The units used to measure and record information. It's the modern form of the metric system and the world's most widely used system of measurement.
What Temperature does water freeze in Celsius?
0° C
(a) Alpha
(b) Acetone
(c) Average
(d) Acceleration
(d) Acceleration
Acceleration is the rate at which Velocity changes.
Ex: the car accelerated at 4 m/s2
True or False?
Energy can be created or destroyed.
False!
Energy cannot be created or destroyed, it can only change forms.
What is the S.I unit for mass?
Kilogram
Kg
What temperature does water boil in Celsius?
100° C
What is the equation for Force (F) using the variables 'm' and 'a'?(hint: Newton's second law)
m=mass
a=acceleration
F=ma
This is Newton's Second law
Force=Mass x Acceleration
Where does the tennis ball have the most potential energy?
In my hand.
What is the difference between mass and weight?
The mass is the amount of matter in it, and the weight is the measurement of gravitational force acting on it.
What are the 3 units to measure temperature?
Fahrenheit, Celsius, Kelvin
What does the variable 'g' stand for?
(a)Acceleration due to gravity
(b)Velocity of given object
(c)Goal of the equation
(d)Mass gained
(a) Acceleration due to gravity
this is the acceleration that is caused by the force of gravity on Earth.
It is equal to 9.8 m/s2
Where is the initial height, and where is the final height?
Initial - In my hand
Final- On the floor
ho=hand
h=floor
How many laws of motion did Isaac Newton create?
3
True or False?
The way to convert Celsius to Kelvin is...
Kelvin = ° Celsius + 273.15
True!
What is the equation for Weight (w) in Newtons.
w=mg
The weight in Newtons is equal to the mass of an object multiplied by the acceleration due to gravity.
Weight=Mass x Acceleration due to gravity.
What is a revolution? In regards of circular motion.
One trip around a circular path.
At what temperature does water boil? In Fahrenheit.
212°F
