buoyancy
What is buoyancy?
An upward force that fluids exert on all matter
What is pressure?
The measure of how much force is acting on a given area.
What is volume?
The amount of space an object takes
Who founded the idea of gravity?
Issac Newton
What is force on an object?
A push or a pull
If an object suspends in water, is it buoyant?
Yes
What causes pressure?
The particles of a substance bouncing on each other due to the space they are in, and due to the particles wanting to be free.
What is mass?
The objects weight
How many law of gravity did Issac Newton come up with?
3 laws
What unit is used to measure force?
Newton (N)
Archimedes
What is the unit of measurement for pressure?
The Pascal (Pa)
Will an object with greater mass, fall faster than an object with smaller mass?
no
What is Newton's first law?
objects in motion stay in motion; objects at rest stay at rest
what is net force?
the total force acting on an object
An object must be what that the water it displaces in order to float?
Lighter
What happens the deeper you go in a fluid (I.E water and our atmosphere)?
The pressure increases
What is density?
the weight of an object per unit of its volume
True or False; all objects exert gravitational force?
True
What is inertia?
The tendency of all objects resist a change in motion
Is Earths atmosphere a fluid, making us buoyant?
Yes
What is the equation for pressure?
p=f/a
What is the equation of density?
d=m/v
What is the acceleration of Earth's gravity toward a falling object?
What is the equation to find average acceleration?
fv-sv/t
