AP Physics -B Exam Review 2024 Questions with Answers 1. What two entities comprise a vector? - Answer>> Magnitude and direction 2. What do you do with any vector that is not on either the x or y axis? - Answer>> Break it up into x and y components using trig, add up the components. 3. How are velocity and speed different? - Answer>> Velocity has a direction and speed does not have direction.

What is natural movement in a gravitational field? - correct answerAll objects move in the direction of the g field on their own. Unnatural movement is against the field (when a force is exerted against the field). What is Displacement? - correct answerDisplacement is the change in location of an object. What is Velocity? - correct answerVelocity is the rate of change of displacement (x) v=x/t What is Acceleration? - correct answerAcceleration is the rate of change of velocity (v) a=v/t...

acceleration, a CORRECT ANSWER The rate of change in velocity; the change in velocity over time. acceleration due to gravity CORRECT ANSWER Acceleration of an object as a result of gravity. average acceleration CORRECT ANSWER The change in velocity divided by the time over which it changes. average velocity CORRECT ANSWER Displacement divided by time over which displacement occurs. deceleration CORRECT ANSWER Acceleration in the direction opposite to velocity; acceleration that resul...

AP Physics B Final Exam 2024 Study Guide 1. A vertical wire carries a current straight down. To the east of the wire, the magnetic field points - Answer>> South 2. A current carrying loop of wire lies flat on a table top. When viewed from above, the current moves around the loop in a counterclockwise sense. What is the direction of the magnetic field caused by this current, OUTSIDE the loop? The magnetic field - Answer>> Points straight down

AP Physics 1 Final Exam| Questions and Verified Answers (2023/ 2024) |100% Correct Q: A uniform bar is lying on a flat table. Besides the gravitational and normal forces (which cancel), the bar is acted upon by two other forces, F1 and F2, which are parallel to the surface of the table. If the net force on the rod is zero, then which one of the following is true? A: The net torque on the bar must also be zero B: The bar can accelerate translationally if F1 and F2 are not applied at the same...

AP Physics 1 Practice Test Question and Answers 2024 1. Balls 1 and 2 are each thrown horizontally from the same height above the level ground, but ball 2 has a greater initial velocity after leaving the thrower's hand. If air resistance is negligible, how do the accelerations of the balls and the times it takes them to hit the ground compare? - Answer>> E: Acceleration a: equal, Time to hit ground: equal

AP Physics 2 Midterm exam 2024 question and answers After the switch is closed and the circuit has reached a steady state, an ideal ammeter is connected between points X and Y, as shown above. The circuit is again allowed to reach steady state. Which of the following correctly indicates the reading on the ammeter and explains why it has that reading? - Answer>> The same as the current in resistor 1, because ammeters have very low resistance and it will create a short between the top and b...
