PRACTICE TESTSfor
PHYSICAL SETTINGREGENTS PHYSICS
STUDENTS
The purpose of this book is to give you an aid to review for the Physical Setting/Physics Regents exam, or your school physics exam. You will find answers and explanations to the questions from four previous exams. Take your time in going through each exam. Try to answer each question on your own before checking the answer and the accompanying explanation. Concentrate on those that you have trouble with. Do not wait until the last minute to start your review. Start well before the Regents exam and do 20 to 25 questions at a sitting. By the time you finish the four exams in this booklet, you should have a good understanding of the wording and types of questions to expect on the Regents, or school physics exam.
Good luck on the exam.

64 Answer Key –– June 2014 Physical Setting Physics
June 2014Part A
1. 1 A scalar is a quantity with magnitude or size only. Since mass has magnitude only, it is a scalar. The others are vectors, having magnitude and direction.
2. 1 Under Mechanics in the RT, find the equation vf 2 = vi
2 + 2ad. Substitution gives vf
2 = 0 + 2(4.0 m/s2)(8.0 m). Solving, vf = 8.0 m/s.
3. 2 In the RT under Geometry and Trigonometry, Right Triangle, find the equations sin θ = a/c and cos θ = b/c. Solving for a (the vertical component) and b (the horizontal component) respectively, gives a = c(sin θ) and b = c(cos θ). Substitution and solving gives a = (15 m/s)(sin 60°) = (15 m/s)(0.87) = 13 m/s and b = (15m/s)(cos 60°) = (15 m/s)(0.50) = 7.5 m/s.
4. 3 Under Mechanics in the RT, find the equation d = vi t + ½ at2. For free fall, a = g, the acceleration due to gravity, which is found on the List of Physical Constants. Substitution gives 500. m = ½(9.81 m/s2)(t2). Solving, t = 10.1 s.
5. 1 Newton’s Third Law of Motion sates that for every action, there is an equal and opposite reaction.
6. 3 On the RT under Mechanics, g is equal to the acceleration due to gravity or the gravitational field strength. Compared to the radius of the Earth, the distance of the mass above the surface is negligible. Consider it at the surface of the Earth. At the Earth’s surface, g = 9.8 m/s2 or N/kg (N/kg = (kg•m/s2)kg = m/s2).
7. 4 Under Mechanics on the RT, find the equation d = vi t + ½ at2. Substitution and solving gives d = (22 m/s)(3.2 s) + ½ (2.4 m/s2)(3.2 s)2 = 83 m.
8. 2 Since the acceleration of the elevator is downward, the force of the elevator floor on the person is less than the persons weight.
9. 2 In the RT under Mechanics, find the equation J = Fnett = Δp. The change in momentum (Δp) is equal to the impulse acting on the object.
10. 1 Find the equation J = Fnett = Δp. For a given change in momentum, the greater the time that the force acts, the smaller the force needed for that change in momentum.
11. 3 An electron is always surrounded by an electric field. Any moving charged particle produces a magnetic field.
