Waves
A type of wave in which matter moves in repeated patterns
Mechanical Waves
Diane and Ben are at the market picking up some groceries. They are pushing the shopping cart in opposite directions. Diane is pushing with 43 N of force. Ben is pushing with 32 N of force. What is the net force of the shopping cart?
11N.
Name the 7 continents
Australia, Asia, Europe, North America, South America, Antarctica
Two or more atoms connected with a chemical bond.
The speed and direction of an object’s motion.
Velocity
Waves transfer ___________ from one location to another without moving ________
energy; matter
A toy car is accelerated with an initial force of 5N. The car has a mass of 0.5 kg. Find the acceleration of the car(include units)
10 m/s2
Name 4 Gods/Goddess that the Ancient Greeks believed in.
Zeus,Poseidon,Ares,Demeter,Persephone,Artemis,Athena...

Define: Amplitude
Amplitude is the distance from the resting point in a wave to the crest.
A type of wave in which the particles move in a perpendicular pattern to the direction the wave is traveling in.
Transverse Wave
What are the 2 components of a force?
How are forces measured?
The two components are strength and direction.
Forces are measured in newtons.
Set, floater, and wipe are terms used in which team sport?
Volleyball
Identify whether it is a chemical or physical change:
Burning of paper.
Chemical change
How do you measure the frequency of a wave?
Number of wave/ time
Based on your understanding of waves, are you able to hear sound in space? Explain your reasoning.
No. Sound waves are a mechanical wave which require matter in which to travel. Space does not have matter to allow it to travel through.
Which of Newton's law applies?
A hockey puck continues to slide along an ice rink after being pushed with an initial force of 50N.
Newton's 1 Law
What country is responsible for creating the Olympic Games?
Greece
Identify whether it is a chemical or physical change: Freezing water to form ice and then leaving it outside to melt into a liquid.
Physical change
A car is traveling at 50 miles/hour on a straight road. Is the car accelerating? Explain.
The car is not accelerating because the speed and direction of motion do not change.

Explain the difference between Evaporation and Transpiration.
Evaporation: The transformation of liquid water into a gas state.
Transpiration: The evaporation of water from plants and trees.
The length of one complete wave cycle. Measured from crest to crest or trough to trough.
