1 Physics 1 Summer Assignment Welcome to the Physics 1- Honors level course. Physics 1 course is an Algebra and Trigonometry based College- Level course in Physics. The following topics will be covered in the course: Kinematics, Force, Work and Energy, Momentum, Circular motion, Rotational motion, Fluids and Thermo Physics, SHM, Electricity, Magnetism and Optics. You will be given a series of assignments to be completed over the summer break. These assignments will help you prepare for next year by strengthening important skills required. Conceptual math problems and physical applications will be practiced and useful basic information will be imparted through these assignments. Investigation of physical phenomena in the course will be helped by the math reviewed. These assignments cover previously learned material in your Math and SIA class, and their understanding is essential for the course. This packet contains 8 sections (A-H). Please answer all questions in a separate sheet of paper. You need to show all work neatly and clearly. When completing (section H) problems, do not just put the answer; you must show all givens, what you are looking for (unknown), equations you are using for a solution, and the plug-in with answer. (See example problem) When working problems follow this format: A drag racer starts from rest, and accelerates at 7.40-m/s 2. How far has it traveled in 2.00-s? Given: v i = 0 a = 7.40 m/s 2 t = 2.00 s Unknown: distance Equation: d = v i t + ½ at 2 Solution: d = (0)(2) + ½(7.4)(2) 2 d = = 14.8 m

2 Due Date: Assignment is due on September 6, 2018 Please note that hand written or typed assignments are welcome. Hand written assignments must be legible and neat. Late assignments will not be accepted. It is best to NOT wait until the last week before school begins to start on this material. Student who do not complete the assignments over the summer have typically not done well in class. Please make the commitment to complete the work. We are looking forward to an exciting year in Physics 1 class. Have a great summer. See you in September. Physics Teachers Physics 1 Summer Assignment All answers are in a separate sheet of paper A. Convert the following metric measurements: 1 hour = 3600 seconds 1 mile = 5280 feet 1 yard = 3 feet 1 meter = 3.28 feet 1 km = 0.62 miles 1 kg = 2.2 lbs 1 lb = 0.45 kg 1 quart = liters 1 m/s = 2.2 miles/hour 1 foot = 12 inches 1 inch = 2.54 cm 1m = 100 cm 1 kg = 1000g mg = g 198g = Kg 8 mm = cm cm = mm 75 ml = L 6.3 cm = mm g = Kg 50 cm = m 5.6 m = cm m = Km 5 L = ml 26,000 cm = m Km = m 16 cm = mm 56,500 mm = Km 6. 1 L = ml 65 g = mg 27.5 mg = g cm = m 2500 m = Km g = kg Km = cm ,900 seconds into days years into minutes

Write the following numbers in scientific notation with 3 significant figures ,000, C. Multiplying Numbers in Scientific Notation 1. (2.5*10 8 ) (1.2*10 1 ) = 2. (1.8*10 3 ) (7.3*10-8 ) = 3. (6.0*10-2 ) (6.1*10-2 ) = 4. (5.5*10 9 ) (4.0*10 11 ) = D. Adding Numbers in Scientific Notation 1. (2.5*10 8 ) + (1.2*10 1 ) = 2. (1.8*10 3 ) + (7.3*10-8 ) = 3. (6.0*10-2 ) + (6.1*10-2 ) = 4. (5.5*10 9 ) + (4.0*10 11 ) =
