Gravity Vocab
A force that exists between any two objects that has mass.
Gravity
Gravity not only pulls down, but to the _______ of the mass.
Center
The force of gravity makes a penguin stick to the ground.
False. The force of gravity pulls a penguin toward the center of the Earth, NOT sticks it to the ground.
Created his theory of gravity after taking a "nap" under a tree.
Isaac Newton.
the orbiting of an object around another (caused by gravity).
Revolution.
A push or pull that is applied to an object.
Force
Gravity applies _______ force to all objects.
equal
Weight is the same as Mass.
False. Weight is affected by the force of gravity. Mass is the amount of space an object occupies.
Known as the father of modern science.
Galileo Galilei
True or False
Only planets have gravity. Stars and moons do not.
False
Everything that has mass has gravity.
the force of attraction between all masses
Gravitational Attraction
In space, an object in motion will stay in motion until acted upon by an outside
force or object
Gravity applies the same force to all objects on Earth, regardless of size.
True.
Who said "What goes up, must come down"?
Sir Isaac Newton.
The amount of time it takes a planet to circle the sun.
A year
The circular or elliptical path of an object as it revolves around another object.
Orbit
This force causes heat and will act upon a moving object causing it to slow down.
Friction
Earth has more gravity than the sun because it is denser.
False, the Sun has more mass, therefore has more gravity.
Name three scientist characters from the Muppets or Science Court Series.
Dr. Bunsen Honeydew and Beaker
Professor Parsons
Julie Bean
Alison Krempel
and the list goes on!
Why do a feather and a hammer hit the ground at the same time on the moon, but not on the Earth?
Gravity pulls them down at the same rate. There is no air (atmosphere) on the moon to cause resistance on the feather there like here on Earth.
a force that is caused by air. The force acts in opposite direction to an object moving through the air.
Air resistance.
If an object moves and no FORCE affects it, it will
keep going!
Due to the difference in mass and gravitational attraction, the earth with less gravity orbits the Sun because it has greater gravity.
True.
Was imprisoned for his ideas on the Universe.
Galileo
If you can see it, touch it, weigh it, it has....
mass.
