This is the direction of its acceleration after it’s left your hand. $300 Question: 1-D Motion What is down? $400 -- 1-D Motion A rock is dropped from rest from a height of 12m. This is how long it takes to hit the ground. $400 Question: 1-D Motion What is 1.56 sec? $500 -- 1-D Motion Speedy the snail accelerates from 2 m/s to 15 m/s at a constant acceleration of 5 m/s2. This is the distance Speedy covers as he accelerates. $500 Question: 1-D Motion What is 22.1m? $100 -- 2-D Motion If the passenger in a convertible throws a rock straight up, this is why it lands back in the passenger’s lap. $100 Question: 2-D Motion What is because both the car and the rock have The same horizontal speed? $200 -- 2-D Motion This is the direction of the velocity vector in projectile motion. $200 Question: 2-D Motion What is tangential to the path? $300 -- 2-D Motion Of dependent or independent, this is which one that describes how the vertical and horizontal motions are related to one another in projectile motion.. $300 Question: 2-D Motion What is independent? $400 -- 2-D Motion If a projectile is fired with V0 = 19 m/s and θ = 200, This is the projectile’s horizontal range. $400 Question: 2-D Motion What is 23.68 m? Bonus: explain when you are allowed to use the range equation. $500 -- 2-D Motion A projectile is fired at V0 = 19 m/s and θ = 200. This is the time of flight if the starting and landing heights are the same. $500 Question: 2-D Motion What is 1.33 sec? $100 -- Vectors If FX = 20 N and FY = 13 N, this is the magnitude of F. $100 Question: Vectors What is 23.9 N? $200 -- Vectors If AX = 6 m/s2 and AY = 7 m/s2, this is the direction (angle) of the acceleration. $200 Question: Vectors What is 49.40? $300 -- Vectors An ice skater is travelling at 12 m/s at an angle of 380 above the X-axis. These are the x- and ycomponents of his velocity. $300 Question: Vectors What are VX = 9.460 m/s and VY = 7.39 m/s? $400 -- Vectors These are the short equations for FX and FY if you know F and θ. $400 Question: Vectors What are FX = Fcos(θ) and FY = Fsin(θ)? $500 -- Vectors It is the means of finding the direction of a vector if You know the x- and y- components. $500 Question: Vectors What is θ = tan-1(y-comp/x-comp)? $100 – Forces ΣF = ? $100 Question: Forces What is ma? $200 -- Forces This is the equation for the force of static friction. $200 Question: Forces What is What is FFS = μSFN? $300 -- Forces For a horizontal surface, FN = this. $300 Question: Forces What is mg, or the weight of the object? $400 -- Forces This is the force of gravity between two 10 kg objects separated by 4m. $400 Question: Forces What is 4.17 X 10-10 N? $500 -- Forces These are the magnitude and direction of the resultant force for the diagram below: 7N 12N 7N 4N $500 Question: Forces What are F = 5.83N and θ = 1490? $100 – Work and Energy This is the Work-Energy theorem. $100 Question: Work and Energy What Work = ∆KE? $200 -- Work and Energy This is the full formula for conservation of energy. $200 Question: Work and Energy What is mghf + ½ mvf2 = mghi + ½ mvi2? $300 -- Work and Energy This is the formula for Work done on an object. $300 Question: Work and Energy What is W = Fdcos(θ)? $400 – Work and Energy If Tarzan is standing on the branch at rest and has a potential energy of 11,000J, this is the value of his kinetic energy when his height above the ground is zero. $400 Question: Work and Energy What is 11,000 J? $500 -- Work and Energy This and that are examples of a conservative and nonconservative force, respectively. $500 Question: Work and Energy What are gravity and friction, for example? $100 -- Catch-all This is the formula for speed in a circle. $100 Question -- Catch-all What is V = 2Πr/T? $200 -- Catch-all This is the conversion of 25 mi/hr into m/s. $200 Question -- Catch-all What is 11.17 m/s? $300 -- Catch-all When a 1 kg rock, 2 kg rock and 3 kg rock are dropped from the same height, it’s the one that hits the ground first. $300 Question -- Catch-all What is they all hit at the same time? $400 -- Catch-all Yes, there is gravity here. $400 Question -- Catch-all Where is the moon? $500 -- Catch-all This is the definition of power. $500 Question -- Catch-all What is work/time or energy/time? Final Jeopardy This is the most awesomest school subject ever and one that all of you should be thankful you get to take. Final Jeopardy Answer What is Physics?
