AC HPAT PHYSICS EXAM GRADED
A+ LATEST UPDATE.
1. DIstance ANS >>> · Distance is a scalar quantity that refers to "how much ground
an object has covered" during its motion.
2. Displacement ANS >>> · 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.

, 3. Position ANS >>> · 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.
4. Speed ANS >>> · 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.
5. Acceleration ANS >>> · Acceleration is the rate of change of velocity with time.
6. Instantenous velocity ANS >>> · 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.
7. A force ANS >>> 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
8. Net force ANS >>> · 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.
