When an object’s velocity changes, which of the following must have occurred?
A unbalanced force acted on the object.
An balanced force acted on the object.
The object started to deviate from motion along a straight line.
The object’s speed and direction remained unchanged.

Potential energy can be thought of as which of the following?
a measure of the amount of power exerted by a system
the ability of a system to store energy
a measure of the kinetic energy that is left in a system
the storage of energy that is available to do work

Heat conduction works primarily because of which of the following reasons?
In a closed system, energy is conserved.
When two objects interact with each other, they exert equal but opposite forces on
each other.
The most likely outcome is for the particles making up the substance to go from a
less likely state to a more likely state.
In the absence of unbalanced forces, an object in motion will continue along with
that motion.

Which of the following is not a similarity between the equation for the electrical
force between charges and the equation for the gravitational force between masses?

The forces can each be either positive or negative.
The forces are each proportional to a property possessed by each of the objects.
The forces decrease with the square of the separation between objects.
The forces increase with the square of the separation between objects.

When two waves, each with identical frequencies and an amplitude of 4 cm,
interact with each other at the same point, which of the following happens?
Without knowing the timing of the waves, we can’t say anything.
The point experiences a shift of 8 cm upwards.
The point experiences no shift at all.
The point experiences a shift of 8 cm downwards.

The atomic number of an element best corresponds to which of the following?

The number of electrons orbiting the nucleus of an atom of that element.
The number of protons in the nucleus of an atom of that element.
The number of neutrons in the nucleus of an atom of that element.

An ionic bond forms where the following happens?
Atoms that like to share electrons interact with each other.
An atom that likes to share electrons interacts with an electron that likes to take
electrons.
An atom that likes to give up an electron interacts with an atom that likes to take
electrons.
Atoms that do not like to share electrons interact with each other.

The properties of a material do NOT depend on which of the following?
The kind of atoms from which the material is made

The way the atoms can be broken apart inside the material

Within a permanent magnet, which of the following is true?
The atomic-level dipole magnets are randomly oriented.
The atomic-level dipole magnets clump together in similar orientations; these
clumps tend to line up with each other in the same direction.
The atomic-level dipole magnets all point in exactly the same direction.
The atomic-level dipole magnets tend to line up with each of their nearest
neighbors.

Which of the following are accurate statements about the nucleus of an atom?
The nucleus contains very little of an atom’s total energy.
The nucleus contains the greatest part of an atom’s total volume.
The interactions within the nucleus of some atoms occasionally send matter and
energy out of the atom.
The interactions within the nucleus alone control chemical behavior of the atom.

When an atom undergoes radioactive decay, which of the following happens?
The parent nucleus loses some of its internal energy and the decay products have a
great deal of kinetic energy.
The parent nucleus converts some of its internal energy into mass and the decay
products have more mass than the parent nucleus.
The parent nucleus converts some of its mass into kinetic energy for the decay
products.
The parent nucleus converts thermal energy into kinetic energy for the decay
products.

Which one of the following is a reason why the Large Hadron Collider is so large?

The detectors must be spread out over many kilometers to catch all of the fastmoving particles.
Fast-moving protons are less likely to collide unless there are very long beams.
As the protons get closer to the speed of light, the acceleration induced by a given
force will decrease in magnitude.
A perfect vacuum cannot be achieved, but the imperfections are diminished in
effect if they are spread over a long distance.
