AP Physics 1 Unit 7 Progress Check A and B Q&A. AP Physics 1 Unit 7 Progress Check A A group of students must conduct an experiment to determine how the location of an applied force on a classroom door affects the rotational motion of the door. The rotational inertia of the door about its hinges is known. The initial angular velocity of the door is zero. Which of the following lists what measuring devices the students need and the measurements they should take to collect the necessary data to te...

AC HPAT Physics Latest Update (2024/2025) Graded A+ DIstance · Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement · 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 · 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 vecto...

STRAIGHTERLINE PHYS 250 EXAM QUESTIONS 2024 STRAIGHTERLINE PHYS 250 EXAM QUESTIONS 2024 WITH GUARANTEED ACCURATE ANSWERS An amusement park game consists of throwing a quarter into a small bowl. If you win, you get to take home a giant purple stuffed elephant. The dish is on a shelf that is 0.4 m above the point where the quarter leaves your hand. The horizontal distance between the bowl and the place where the quarter leaves your hand is 1.8 m. Ignoring air drag, if you toss the quarter a...

Why does a figure skater spin faster as she pulls limbs in? - Answer Angular velocity increases, moment of inertia decreases what is the law of acceleration - Answer Rate of acceleration is proportional to unbalanced load and inversely proportional to inertia How does a dumbbell and tape fall at the same rate? - Answer All objects fall at an acceleration of 9.81 m/s2 - more mass = more weight, more gravity is pushing down - overcomes their greater inertia

Traumatic brain injury - correct answer an acquired brain injury due to damage to the brain as a result of the sudden application of mechanical energy from external physical forces Penetrating (open) TBI - correct answer when a foreign object enters the brain; pathology concentrated around the path of the intruding object Contact (closed) TBI - correct answer when the head suddenly at force comes into contact with a stationary object; brain compresses against the inner surface of the skull...
