Motion
A change in speed, direction or both
What is acceleration?
The chemical formula for diphosphorus pentoxide.
P2O5
Includes both liquids and gasses
What are fluids?
An object at rest will stay at rest, and an object in motion will stay in motion, unless acted upon by an unbalanced force
What is Newton's first law of motion
The charge on a chloride ion in AlCl3 is
What is -1?
F= ma
What is Newton’s 2nd law?
Force that opposes the motion of objects as they move past one another
What is friction?
Pressure within a fluid is distributed equally throughout the fluid
What is Pascal's Principle?
Momentum depends upon
force only
velocity and friction
weight and mass
mass and velocity
mass and velocity
Why do equations need to be balanced?
matter can't be created or destroyed, so reactants' mass has to = product's mass
Carter runs 30ft north, 20 ft west, and 30 ft south. What is the distance and displacement for Carter?
Distance = 80ft
displacement = 20ft W
What is the molar mass of P5O10
155 +160
315g/mol
Buoyant force is equal to the weight of the fluid displaced
What is Archimedes's principle?
An object accelerates 8.2 m/s2 when a force of 20.1N is applied to it. What is the mass of the object?
F=ma
2.5 kg
Name the compound Na3PO4
sodium phosphate
Resistance to change in the motion of an object
What is inertia?
A chemical bond that forms when atoms share electrons.
What is a covalent bond?
The faster a fluid moves the lower the pressure within it
What is Bernoulli's principle?
3 forces act upon a crate that is initially at rest. Once force is acting on the crate with a magnitude of 3N East, another force with 8N west, and the last force is 5N East. Draw a free body diagram, determine the net force acting on the object, and describe the resulting motion of the crate.
Net force is 0N. Object will not move as it is balanced forces acting upon it.
KClO3 -> KCl + O2
If you start with 1 mole of potassium chlorate, how many moles of oxygen can be made?
2KClO3 -> 2KCl + 3O2
1.5 mol O2
Rachel walks 3km north, and then turns east and walks 6km. What is her distance and displacement?
Distance = 9km
d= 6.7km NE
For every action there is an equal and opposite reaction
What is Newton’s 3rd law?
If the area of a box touching the ground is 1.5 square meters, and its' weight is 2,700 Newtons. What pressure does the box exert on the ground?
What is 1,800 Pa?
What is 1,800 N/ sq. m
