S2 BM Notes Scavenger & Summary Name AP Physics Complete the following unit review guides for each unit. This is due the day of your benchmark (along with your Quarter 3 project!). -65405000I SPY, WITH MY LITTLE EYE… -66040571500THINK, THINK, THINK! Find this thing in your notes. Describe it and record relevant details in this box. Solve this conceptual question with little to no math, just your brain! -60071016954500NEVER GET IN A CAR WITH A STRANGER WHO OFFERS TO DO YOUR MATH PROBLEMS. -66992513843000MINE YOUR NOTES… DIG UP GEMS & KEEP THEM SAFE UNTIL THE EXAM! They might seem nice at the time, but that Stranger Danger would be doing you a disservice. Practice makes perfect, so complete these problems to jog your math memory. Use another sheet of paper if necessary. Find 3-5 main takeaways that you will need to know for the exam. Record them and make a note of where they are in your materials so you can go back to them to study the details. Unit 1 – Kinematics -65405000I SPY, WITH MY LITTLE EYE… -66040571500THINK, THINK, THINK! A Projectile Motion table! A person trying to throw a ball as far as possible will run forward during the throw. Explain why this increases the distance of the throw. -60071016954500NEVER GET IN A CAR WITH A STRANGER WHO OFFERS TO DO YOUR MATH PROBLEMS. -66992513843000MINE YOUR NOTES… DIG UP GEMS & KEEP THEM SAFE UNTIL THE EXAM! A ball with a horizontal speed of 1.25 m/s rolls off a bench 1.00 m above the floor. a. How long will it take the ball to hit the floor? b. How far from a point on the floor directly below the edge of the bench will the ball land? Unit 2 – Forces -65405000I SPY, WITH MY LITTLE EYE… -66040571500THINK, THINK, THINK! An inclined plane! A ball is thrown straight up. Taking the drag force of air into account, does it take longer for the ball to travel to the top of its motion or for it to fall back down again? -60071016954500NEVER GET IN A CAR WITH A STRANGER WHO OFFERS TO DO YOUR MATH PROBLEMS. -66992513843000MINE YOUR NOTES… DIG UP GEMS & KEEP THEM SAFE UNTIL THE EXAM! The three ropes shown are tied to a small, very light ring. Two of the ropes are anchored to walls at right angles, and the third rope pulls as shown. What are T1 and T2, the magnitudes of the tension forces in the first two ropes? 2235200-57150000 Unit 3 – Circular Motion &Gravity -65405000I SPY, WITH MY LITTLE EYE… -66040571500THINK, THINK, THINK! Weightlessness! 23253702667000A ball on a string moves in a vertical circle (shown). Draw a FBD. When the ball is at its lowest point, is the tension in the string greater than, less than, or equal to the ball’s weight (or is it impossible to tell)? At its highest point? Explain. -60071016954500NEVER GET IN A CAR WITH A STRANGER WHO OFFERS TO DO YOUR MATH PROBLEMS. -66992513843000MINE YOUR NOTES… DIG UP GEMS & KEEP THEM SAFE UNTIL THE EXAM! Satellite A orbits a planet with a speed of 10,000 m/s. Satellite B is twice as massive as satellite A and orbits at twice the distance from the center of the planet. What is the speed of satellite B? Assume that both orbits are circular. Unit 4 – Energy -65405000I SPY, WITH MY LITTLE EYE… -66040571500THINK, THINK, THINK! An isolated system! A spring gun pointed straight upward launches a plastic ball at speed v and it reaches a maximum height h. The spring is then compressed twice the distance it was on the first shot. a. By what factor is the ball’s launch speed increased? Explain. b. By what factor is the ball’s max. height increased? Explain. -60071016954500NEVER GET IN A CAR WITH A STRANGER WHO OFFERS TO DO YOUR MATH PROBLEMS. -66992513843000MINE YOUR NOTES… DIG UP GEMS & KEEP THEM SAFE UNTIL THE EXAM! A 10 kg box is pushed with a force of 23 N over a distance of .7 meters. If the final velocity of the box is 1.4 m/s, how much energy is lost to thermal energy due to friction? Bonus challenge: What is the coefficient of friction? Unit 5 – Momentum -65405000I SPY, WITH MY LITTLE EYE… -66040571500THINK, THINK, THINK! Elastic & Inelastic collisions! Viewed from above, a small puck is sliding to the right with a horizontal, frictionless surface. A force is applied to the puck for a short time so that it travels straight downward with the same magnitude of momentum as before. What is the direction of the force that must have been applied to the puck? -60071016954500NEVER GET IN A CAR WITH A STRANGER WHO OFFERS TO DO YOUR MATH PROBLEMS. -66992513843000MINE YOUR NOTES… DIG UP GEMS & KEEP THEM SAFE UNTIL THE EXAM! A small, 100 g cart is moving at 1.20 m/s on a frictionless track when it collides with a larger, 1.00 kg cart at rest. After the collision, the small cart recoils at 0.850 m/s. What is the speed of the large cart after the collision? Unit 6 – Rotation -65405000I SPY, WITH MY LITTLE EYE… -66040571500THINK, THINK, THINK! Rotational Inertia! If you grasp a hammer by its lightweight handle and wave it back and forth, and then grasp it by its much heavier head and wave it back and forth, as in the figure, you’ll find that you can wave the hammer much more rapidly in the second case, when you grasp it by the head. Explain why this is so. -60071016954500NEVER GET IN A CAR WITH A STRANGER WHO OFFERS TO DO YOUR MATH PROBLEMS. -66992513843000MINE YOUR NOTES… DIG UP GEMS & KEEP THEM SAFE UNTIL THE EXAM! How close to the right edge of the 56 kg picnic table can a 70 kg man stand without the table tipping over? 2059940-97155000 Unit 7 – Oscillations -65405000I SPY, WITH MY LITTLE EYE… -66040571500THINK, THINK, THINK! Period of oscillation! The graph shows the position of an object on a pendulum. a. At what time(s) is the object moving to at a maximum speed? 1531620-42926000b. At what time or times is the particle instantaneously at rest? c. What is the period of motion? -60071016954500NEVER GET IN A CAR WITH A STRANGER WHO OFFERS TO DO YOUR MATH PROBLEMS. -66992513843000MINE YOUR NOTES… DIG UP GEMS & KEEP THEM SAFE UNTIL THE EXAM! A 200 g mass attached to a horizontal spring oscillates at a frequency of 2.0 Hz. At one instant, the mass is at x = 5.0 cm and has v = 30 cm/s. Determine: a. The period. b. The maximum speed. d. The maximum stretch/compression. Unit 8 – Waves & Sound -65405000I SPY, WITH MY LITTLE EYE… -66040571500THINK, THINK, THINK! Harmonics for open-open and open-closed tubes! Rank in order, from largest to smallest, the wavelengths ?1, ?2, & ?3 for sound waves (in the same medium) having frequencies f1 = 100 Hz, f2 = 300 Hz, and f3 = 800 Hz. Explain. -60071016954500NEVER GET IN A CAR WITH A STRANGER WHO OFFERS TO DO YOUR MATH PROBLEMS. -66992513843000MINE YOUR NOTES… DIG UP GEMS & KEEP THEM SAFE UNTIL THE EXAM! A speaker is connected such that it produces sound above and below water concurrently. A sensor some distance away can sense the signals, again from above and below water. If there is a 4 second difference between the sensor readings above and below water, what is the distance between the speaker and sensor? Unit 9 – Charge & Circuits -65405000I SPY, WITH MY LITTLE EYE… -66040571500THINK, THINK, THINK! Electric field lines/vectors! Two charged particles near each other put a force of 2 N on each other. Suppose the charge on each particle is doubled and the distance between them is tripled. What is the new force that the charges put on each other? -60071016954500NEVER GET IN A CAR WITH A STRANGER WHO OFFERS TO DO YOUR MATH PROBLEMS. -66992513843000MINE YOUR NOTES… DIG UP GEMS & KEEP THEM SAFE UNTIL THE EXAM! If R = 2 ohms and the current out of the battery is 5 amps, find the current and voltage across each resistor, and the voltage on the battery. 1606550-77787500
