AP Physics 1 Review 1 Exam UPDATED
ACTUAL QUESTIONS AND CORRECT
ANSWERS
Vector - CORRECT ANSWER quantity that involves both magnitude and direction
Scalar - CORRECT ANSWER a quantity that does not involve a direction
Average speed formula - CORRECT ANSWER total distance/ time
D/t
Slope of velocity-versus-time graph - CORRECT ANSWER acceleration
Newton's second law - CORRECT ANSWER
Newton's third law - CORRECT ANSWER for every action there is an equal but opposite
reaction (action/ reaction pair)
Newton - CORRECT ANSWER kg m/s^2
Unit of force
Inertia - CORRECT ANSWER the property of objects to naturally resist changes in their states
of motion
Weight (of an object) - CORRECT ANSWER the gravitational force exerted on it by the Earth
or whatever planet Fw or Fg= mg
Normal force - CORRECT ANSWER component of force that's perpendicular to the surface
, Free-body diagram - CORRECT ANSWER A diagram that shows all the forces acting on an
object
Friction force - CORRECT ANSWER the component of the contact force that's parallel to the
surface
Static friction - CORRECT ANSWER occurs when there is no motion between two objects
(friction that holds an object still)
Mu - CORRECT ANSWER coefficient of friction
Kinetic friction - CORRECT ANSWER occurs when there is relative motion (when there's
sliding)
Kinetic energy - CORRECT ANSWER the energy of an object due to motion
K= .5mv^2
Potential energy - CORRECT ANSWER the energy an object or system has by virtue of its
position
Ug - gravitational potential energy
△Ug= mg△h
Uniform circular motion - CORRECT ANSWER -speed is constant
- velocity is not constant because the direction of velocity is always changing
-in order to produce acceleration there must be a force towards the center
Centripetal force - CORRECT ANSWER Caused by something - friction, tension, gravity.
Always points towards the center.
Newton's law of gravitation - CORRECT ANSWER any two objects in the universe exert an
attractive force on each other called the gravitational force
