#### Transcript of Benchmarks SC.6.P.13.3 and SC.7.P.10.3

SC.6.P.13.3
Analyzing Position-Time Graphs
This benchmark is about balanced and unbalanced forces acting on a object that changes its speed, and direction of motion.
Question: What's the difference between balanced and unbalanced forces?
Answer: Balanced forces are equal in size but opposite in direction. Unbalanced forces causes a change in the motion of an object.
Benchmarks SC.6.P.13.3 and SC.7.P.10.3

Question
Q: In a game of tug-of-war , you pull on the rope with a force of 100 N to the right and your friend pulls on the rope with a foce of 100 N to the left. What is the net force on the rope?
a. 200 N to the right
b. 200 N to the left
c. 0 N
d. 100 N to the right

Vocabulary
SC.7.P.10.3
Light Reflection; Light Refraction
This benchmark is about light waves, sound waves, and other waves that move at different speeds in different materials.
Question: What materials can light waves and sound waves move through?
Answer: Sound waves can move through air and light waves can move through both vacuums and air.
Question
Q: What is reflection and refraction?
A: Reflection is when light bounces off an object such as a prism and gives back visible light ( ROYGBIV ). Refraction is the bending of light
.
Benchmarks SC.6.P.13.3 & SC.7.P.10.3
The correct answer is C. 0 N
Balanced Force
: a set of forces on an object that cancel each other out
Force
: a push or pull exerted on an object in order to change the motion of the object
Net force
: the combination of all the forces acting on the object
Newton
: the SI unit for force
Unbalanced Force
:
a set of forces exerted on an object that change the motion of the object
Velocity
: the speed of an object with a particular direction
Vocabulary
Reflection
: the bouncing back of a particle or wave that strikes the boundary between two medias
Refraction
: the change in direction of a wave as it crosses the boundary between two medias in which the wave travels at different speeds
Sound Wave
: a wave of compression and rarefaction
Electromagnetic Spectrum
: the range of wavelengths or frequencies over which electromagnetic radiation extends
Light Wave
: the movement of light conceptualized as a wave, defined by such properties as reflection, refraction

I hope you learned something from these benchmarks and thank you for participating !!!

Question
Q: Which of the following is true about mass and weight?
a. Mass and Weight are not related.
b. Mass is always the same, weight may change
c. Weight is always the same, mass may change
d. Mass depends on gravity, weight does not
The correct answer is B. Mass is always the same , weight may change.
Question
Which of the following is a unit of mass?
a.Gram
b.Pound
c.Degree
d.Ounce
The correct answer is A. Gram
Question
What is a medium?
a. matter
b.energy
c. both matter and energy
d. neither matter nor energy

The correct answer is b. energy
Question
When a wave hits a surface through which it CANNOT pass and bounces back, it undergoes
a. reflection
b. refraction
c. constructive interfernece
d. destructive interference

The correct answer is a. reflection
My prezi based on the benchmarks SC.6.P.13.3 and SC.7.P.10.3 which benchmark SC.6.P.13.3 is about balanced and unbalanced forces, and benchmark SC.7.10.3 is about reflection and refraction ( when light bends). I hope you enjoy this prezi and participate in the questions. Thank you!!!
