Waves
A type of wave in which matter moves in repeated patterns
Mechanical Wave
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
The energy of motion is known as __________ energy
Kinetic
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 6N. The car has a mass of 2 kg. Find the acceleration of the car(include units)
3 m/s2
Name 4 Gods/Goddess that the Ancient Greeks believed in.
Zeus,Poseidon,Ares,Demeter,Persephone,Artemis,Athena...
What are the 3 types potential energy we discussed in class?
Chemical potential energy
Elastic potential energy
Gravitational potential energy
The law that states that energy cannot be created or destroyed but is simply transferred from one object to another
The law of conservation of energy.
True or False: The human wave seen at stadiums fits the scientific definition of a wave. Explain your answer.
True. Matter doesn't move from one location to another but energy is transferred.
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
What are 2 factors that potential energy depends on?
Mass and Height
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.
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
What are 2 factors that kinetic energy depends on?
Speed and Mass
Define: Wave
A disturbance that transfers energy from one location to another without moving matter.
