Temperature
Name three different temperature scales.
Fahrenheit
Celsius
Kelvin
Who was the first scientist to define gravitational force?
Isaac Newton
How do you calculate speed?
Speed equals distance divided by time
Energy that an object has due to its motion.
Kinetic
In Fahrenheit, what degrees does water boil?
212 degrees F
This is the official scale used by the US and a few other countries.
Fahrenheit
What is the law of inertia?
Newton's First law that states an object in motion will stay in motion unless acted upon by an outside force.
Which is faster, the speed of light or the speed of sound?
Speed of light
Energy stored in an object possesses due to it's motion.
Potential energy
In Celsius, what is the freezing point?
0 degrees C
The temperature scale used by the rest of the world
Celsius
According to Newton's Second Law, how do you calculate force?
Force equals mass times acceleration
The speed of sound is 4.3 times faster when traveling through this substance.
Water
Energy stored in objects by tension.
Example: Stretched rubber bands or compressed springs.
Mechanical energy.
Decreasing the force on an object will _________ the acceleration it experiences.
a. decrease
b. increase
c. not enough information
a. decrease
Temperature scale mostly used in science and engineering
Kelvin
Finish the sentence...
For every action there is an ________ ____ ________ _________.
equal and opposite reaction. Newton's 3rd law
The acceleration of an object is equal to what?
The net force acting on it.
Energy stored within chemical bonds
Example: batteries, petroleum, natural gas and coal.
Chemical energy
A book sitting up on a shelf is an example of...
a. gravitational force
b. kinetic energy
c. potential energy
d. mechanical energy
c. potential energy
3 Part Question
1. Scale based on freezing point at 32 degrees
2. Scale for absolute zero.
3. Scale based on boiling point at 100 degrees
1. Fahrenheit
2. Kelvin
3. Celsius
How do you calculate acceleration?
Acceleration equals force divided by mass
Which weighs more a pound of feathers or a pound of bricks.
They are both a pound so they weigh the same.
What kind of energy is from the sun?
Radiant energy
__________ energy can be potential OR kinetic
a. Thermal
b. Radiant
c. Mechanical
d. Sound
C. Mechanical because it can come from built up tension or an object's movement.
