If two people are pushing a desk in opposite directions and the desk doesn’t move, what forces are being applied?
Balanced Forces
What does NEO stand for?
Near Earth Objects
What is Newton's First Law?
An object at rest stays at rest and an object in motion stays in motion unless acted upon by an external, unbalanced force.
What invisible force acts downward on all objects?
Gravity
Based on the similarities and differences between two skeletons, what can you infer about the two animals?
They are most likely related.
If two force arrows of the same length were pointing the same direction on an object, would the object be moving or at rest?
The object would be in motion.
What is a solar eclipse?
What is Newton's Third Law?
For every action, there is an equal and opposite reaction
What variables might affect the magnetic repulsion strength between magnets?
The number of magnets and their distance from each other.
What patterns might you find when you compare skeletal structures in modern and extinct organisms?
Many modern and extinct organisms share anatomical structures and features.
How does mass affect motion?
Objects with more mass require more force to move the objects. Objects with less mass require less force to move.
What is a lunar eclipse?
When the Earth passes BETWEEN the Sun and the Moon, casting a shadow on the moon.
What tools do athletes have to help protect themselves in a collision? Please provide examples.
Protective gear like helmets, pads, and gloves
As mass of a planet INCREASES gravity of the planet ___________(INCREASES or DECREASES).
Increases
What is relative age dating?
What is absolute age dating?
Relative Age Dating is when they look at the different layers to determine the oldest and youngest.
Absolute Age Dating is when they can determine a more specific age or date range.
How does force affect motion?
The stronger a force, the more motion an object can have. The weker a force, the less motion an object can have.
What criteria makes an asteroid a threat?
The size of the asteroid.
If two people collide, who feels the force from the collision?
Both people will feel the impact from the collision.
How would an object feel on mars compared to on Earth and why?
An object on Mars would feel much lighter than on Earth since the gravitational force on Mars is less.
How can discovering more evidence make the fossil record more reliable?
If more fossils are discovered, it can help fill gaps and help us understand how organisms fit into the fossil record. It will help make the bigger picture clearer.
What is the evidence for energy in a thermal store and what is the evidence for energy in a kinetic store?
Thermal= heat
Kinetic= motion
Why do we have seasons?
The earth is tilted on its axis. This means that different places on Earth get different amounts of light at different times of year.
Why is important to conduct tests on helmet prototypes?
It allows us to collect data that helps us evaluate how well the prototype works (solve the design problem).
What different variables do you have to now when determining the gravitational force between two objects?
Mass and Distance
Which two animals share a more recent common ancestor—the pig and the whale, or the whale and the fish?
The pig and the whale
