A change in speed, direction or both

What is acceleration?

100

The chemical formula for diphosphorus pentoxide.

P2O5

100

Includes both liquids and gasses

What are fluids?

100

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

100

The charge on a chloride ion in AlCl3 is

What is -1?

200

F= ma

What is Newton’s 2nd law?

200

Force that opposes the motion of objects as they move past one another

What is friction?

200

Pressure within a fluid is distributed equally throughout the fluid

What is Pascal's Principle?

200

Momentum depends upon

force only

velocity and friction

weight and mass

mass and velocity

mass and velocity

200

Why do equations need to be balanced?

matter can't be created or destroyed, so reactants' mass has to = product's mass

300

Carter runs 30ft north, 20 ft west, and 30 ft south.  What is the distance and displacement for Carter?

Distance = 80ft

displacement = 20ft W

300

What is the molar mass of P5O10

  155 +160

315g/mol

300

Buoyant force is equal to the weight of the fluid displaced

What is Archimedes's principle?

300

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

300

Name the compound Na3PO4

sodium phosphate

400

Resistance to change in the motion of an object

What is inertia?

400

A chemical bond that forms when atoms share electrons.

What is a covalent bond?

400

The faster a fluid moves the lower the pressure within it

What is Bernoulli's principle?

400

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.
