200
if the volume decreases, then the ________ increases.
What is pressure?
200
the attraction or joining of two different objects or fluids to each other.
What is Adhesion?
200
A force which involves positive and negative charged particles.
What is Electrostatic force?
300
if a person's mass is 45kg, their weight on Jupiter is ________ (Jupiter's gravity is 2.35 times stronger than Earth)
What is 1036.35N?
300
A group of forces that have an effect by touching (ex. twist, bend, push).
What is contact forces?
300
a change of shape without being being forced into a smaller volume.
What is deformation?
300
the strength of which particles of an object or fluid attract each other.
What is cohesion?
300
A German-born physicist who developed the general relativity theory as well as quantum theory.
Who is Albert Einstein?
400
On Earth a person's mass is 45kg. On a planet with twice the size of Earth, the mass of that person is _______.
What is 45kg?
400
Forces with equal strength and opposing each other in direction.
What is Balanced forces?
400
A device which creates and stores pressurized gas.
What is an air compressor?
400
H2O molecules have a ________ which gives it a dipole nature, which means one end is slightly positive and the other is slightly negative.
What is Polarity?
400
If gravity is pulling us towards the center of the Earth, why do we not sink into the Earth?(do not have to answer in jeopardy format)
Because the ground we stand on provides a force upwards which balances out gravity.
500
If gravitational forces are two masses that attract each other at a close distance, how come we do not attract anything? (do not have to answer in jeopardy format)
Because the Earth's mass is so massive everything is attracted to Earth a lot more than us.
500
When the net force of an object is 0, then the object is __________.
What is stationary or moving at a constant speed?
500
compressing liquid or gas, which is easier, why? (do not have to answer in jeopardy format)
Air, because air particles are more spread apart, so they have more room to compress. Liquids does not compress because there aren't any room for the particles to move together.
500
Why do fluids adhere to certain surfaces?(do not have to answer in jeopardy format)
because of the polarity of water molecules that makes them attracted to certain surfaces.
