100
This scientist and philosopher developed the universal law of gravity
Who is Issac Newton?
100
The scientist that observed that all object fall at the same rate due to gravity
Who is Galileo Galilei
100
The tendency of all objects to resist any change of motion, and it is based on mass.
What is inertia
100
The upward force that fluids exert on all matter
What is the buoyant force
100
Liquids and gases are examples of _______
What is fluids
200
A force of attraction between two objects due to their masses.
What is gravity
200
The friction that falling objects feel when traveling downwards in the sky
What is air resistance
200
Every force has an equal and opposite reactive force
What is Newton's 3rd law
200
An object will sink if the buoyant force is ________ than the weight of the object
What is less
200
The equation used to calculate pressure
What is p=F/A or pressure is equal to force per unit area
300
If the distance between two objects increase, then the force of gravity between them will _______.
What is decrease
300
An object does this when it falls from the force of gravity but there is no air
What is free falling
300
Objects will not change their velocity unless acted on by an unbalanced force.
What is Newton's 1st law
300
Objects will sink or float based on this physical property of matter. It is the amount of mass per unit volume
What is density
300
The weight of the air on our planet
What is atmospheric pressure
400
This measurement can change if you were in outer space or on the Moon, and is effected by the force of gravity.
What is weight
400
The curved path an object follows when thrown or propelled in the air near the surface of our planet.
What is projectile motion
400
This makes Newton's 1st law hard to observe on our planet
What is friction/air resistance
400
Three ways to change the overall density of an object
What is changing the shape, changing the volume or changing the mass of the object
400
The lower you are in fluids, whether air or water, the _______ pressure you feel
What is more
500
A nonmoving object that is kept in place due to the balanced net forces of gravity, tension and friction.
What is a static object
500
This takes place when an object has reached it's top speed falling due to the force of air resistance is equal to the force of gravity.
What is terminal velocity
500
The equation that Newton's 2nd law states
What is F=ma or Force = Mass x Acceleration
500
State Archimedes' Principle
What is the buoyant force on an object is equal to the weight of the water being displaced
500

What is fluids move/flow from where the pressure is high to where the pressure is low
