Space 1
Why is it advantageous to build telescopes on higher elevation?
Less light pollution.
Which energy relies on how fast the object is moving?
Kinetic
What is velocity?
Speed + Direction
Name the force that is constantly pulling down on objects.
Gravity
What type of galaxy is the Milky Way?
Spiral
What is dark matter?
Matter that cannot be seen and can only be detected by its gravitational effects.
In a swing-set, where is potential energy the greatest?
At the very top of the swing
What is the label for acceleration?
m/s2
What is an independent variable?
Variable that is being changed throughout the experiment.
Name 3/8 parts of the sun.
Convection Zone, Radiation Zone, Core, Sun-Spot, Corona, Chromosphere, Photosphere, Prominence
Give the definition of a light-year.
Distance that light travels in one year
Which energy relies on how high the object is in the air?
Potential
What is the speed equation?
Speed = Distance / Time
Name the force that happens when 2 objects rub against each other.
Friction
What is dark energy?
Energy that could be causing the expansion of the universe.
Name the 3 different types of galaxies.
- Spiral
- Elliptical
- Irregular
On a graph, what does it mean when a line is completely horizontal?
The object is not moving
What is something we use to tell if an object has moved from its original place?
Reference Point
What is a dependent variable?
A variable in which its value is dependent upon another variable.
What is 25 times more massive than the sun?
Black Hole
Recite the life cycle of a star (Less mass side).
Stellar Nebula -> Average Star -> Red Giant -> Planetary Nebula -> White Dwarf
Where is kinetic energy the greatest in a pendulum system?
At the lowest point
What does it mean when an object has constant velocity?
It has an acceleration of 0
What is a constant in an experiment?
Something that has to remain constant in order for the experiment to be considered valid.
Recite the life cycle of a star (Massive Side).
Stellar Nebula -> Massive Star -> Red Supergiant -> Supernova -> Black hole or Neutron Star
