Human Systems
What system is responsible for transporting blood throughout the body?
Circulatory System
What type of energy does a moving object have?
Kinetic Energy
A push or pull is known as a...?
Force
What is the main gas released by burning fossil fuels that contributes to climate change?
Carbon Dioxide
During which moon phase does a solar eclipse occur?
New Moon
Name two organs that are part of the respiratory system
Lungs, Trachea, Diaphragm, etc.
What type of energy is stored energy?
Potential Energy
How does friction affect the motion of a moving object? Why?
Slows it down, force is acting in the opposite direction of the object's motion.
Which is faster, sound or light? Why?
Light is faster, as it travels through a vacuum. Sound travels through a physical medium
What causes tides on Earth?
Gravitational pull between Earth & Moon, due to the Moon's ***
Name the system that includes the brain and spinal cord
Nervous System
Energy cannot be created or destroyed, only .... ________ or __________
Transformed or Transferred
What law states that objects in motion stay in motion unless acted on by a force?
Newton's 1st Law
Define consumerism, and explain how does it contribute to climate change?
Buying more things than we need. It increases pollution and greenhouse gas emissions from factories, transportation, and waste
How long does it take for the Earth to orbit the Sun?
365 days
What are the 2 functions of the digestive system?
1. Digestion (breaking down food)
2. Absorption (nutrients)
What is the equation for potential energy?
PE = m * g * h
What happens to an object's motion when an unbalanced force acts in the same direction as the object is already moving?
The object speeds up (accelerated)
What are coal, oil, and natural gas examples of, and why do they contribute to climate change?
Fossil Fuels, they release CO2 when burned for energy.
What was the Antikythera mechanism?
The Antikythera Mechanism is an ancient Greek device, often called the world’s first computer. Used to predict astronomical events such as eclipses.
Name two systems that work together to deliver oxygen to muscles, and briefly explain how it works.
Respiratory and Circulatory
Name 1 (of 2 possible) energy transformations that occur when a flashlight is turned on.
What are chemical to electrical, and electrical to light energy
A car goes 100 km in 2 hours. What is its average velocity? (units!)
50 km/hr
What is wavelength, and how does it relate to the amount of energy—do shorter or longer wavelengths carry more energy?
the distance between two wave crests, shorter wavelengths have more energy.
How does the speed of the Moon’s rotation on its axis compare to the speed the Moon orbits around the Earth? How does this affect our viewing from Earth?
Moon has the exact same rotation as its revolution - resulting in us only ever seeing one side of the moon.
