AC HPAT Physics Exam Questions With
Correct Answers
DIstance - CORRECT ANSWER✔✔-· Distance is a scalar quantity that refers to
| | | | | | | | | | |
"how much ground an object has covered" during its motion.
| | | | | | | | | |
Displacement - CORRECT ANSWER✔✔-· Displacement is a vector quantity that
| | | | | | | | | |
refers to "how far out of place an object is"; it is the object's overall change in
| | | | | | | | | | | | | | | | |
position.
Position - CORRECT ANSWER✔✔-· Position is a place where someone or
| | | | | | | | | | |
something is located or has been put. In physics, position is usually a number on
| | | | | | | | | | | | | | |
an axis. ... Position is a vector, because direction matters. But distance is a scalar.
| | | | | | | | | | | | | | |
Distance is how far you've traveled.
| | | | |
Speed - CORRECT ANSWER✔✔-· Speed is the distance traveled per unit of time. It
| | | | | | | | | | | | |
is how fast an object is moving. Speed is the scalar quantity that is the magnitude
| | | | | | | | | | | | | | | |
of the velocity vector. It doesn't have a direction.
| | | | | | | | |
Acceleration - CORRECT ANSWER✔✔-· Acceleration is the rate of change of
| | | | | | | | | | |
velocity with time. | |
Instantenous velocity - CORRECT ANSWER✔✔-· Instantaneous velocity is the
| | | | | | | | |
velocity of an object in motion at a specific point in time. This is determined
| | | | | | | | | | | | | | |
similarly to average velocity, but we narrow the period of time so that it
| | | | | | | | | | | | | |
, approaches zero. If an object has a standard velocity over a period of time, its
| | | | | | | | | | | | | | |
average and instantaneous velocities may be the same.
| | | | | | |
A force - CORRECT ANSWER✔✔-a force is any interaction that, when unopposed,
| | | | | | | | | | | |
will change the motion of an object. A force can cause an object with mass to
| | | | | | | | | | | | | | | |
change its velocity (which includes to begin moving from a state of rest), i.e., to
| | | | | | | | | | | | | | |
accelerate. Force can also be described intuitively as a push or a pull
| | | | | | | | | | | |
Net force - CORRECT ANSWER✔✔-· Net force is the vector sum of forces acting
| | | | | | | | | | | | | |
on a particle or body. The net force is a single force that replaces the effect of the
| | | | | | | | | | | | | | | | |
original forces on the particle's motion. It gives the particle the same acceleration
| | | | | | | | | | | | |
as all those actual forces together as described by the Newton's second law of
| | | | | | | | | | | | | | |
motion.
Uniform vs. non-uniform motion - CORRECT ANSWER✔✔-· Difference between
| | | | | | | | |
uniform and non-uniform motion with examples. In Uniform motion, movement
| | | | | | | | | |
of a body is along the straight line with constant speed. In non uniform motion,
| | | | | | | | | | | | | | |
movement of a body is along the straight line with variable speed. In uniform
| | | | | | | | | | | | | |
motion, body covers equal distance in equal interval of time
| | | | | | | | |
What is the difference between constant, instantaneous, and average speed? -
| | | | | | | | | | |
CORRECT ANSWER✔✔-· constant speed is where the speed is the same
| | | | | | | | | | |
throughout and instantaneous speed is speed given at any moment and average
| | | | | | | | | | | |
speed is a total distance traveled divided by the amount of time it took to travel
| | | | | | | | | | | | | | | |
it.
Newtons Laws - CORRECT ANSWER✔✔-Newton's first law states that every object
| | | | | | | | | |
will remain at rest or in uniform motion in a straight line unless compelled to
| | | | | | | | | | | | | | | |
change its state by the action of an external force. The second law states that the
| | | | | | | | | | | | | | | |
