Which of these is not part of the scientific method? - Experimentation - Obtain funding - Formulating a hypothesis 2. An automotive crash-test engineer would fall under what subfield of physics? - Mechanics - Optics - Electricity and magnetism 3. What is the distinction between explanations provided by science and religion? - Truth - Testability - Simplicity ## **Describing motion** 1. The slope of a distance versus time graph is the - Acceleration - Velocity - Distance 2. Police officers patrolling a highway are enforcing which measure? - Instantaneous velocity - Average speed - Instantaneous speed 3. Which of these would not be an example of a vector? - Distance - Speed - Acceleration ## **Falling objects and projectile motion** 1. The horizontal speed of a projectile: - Remains constant - Is zero - Sometimes increases and sometimes decreases 2. The vertical speed of a projectile: - Remains constant - Is zero - Sometimes increases and sometimes decreases 3. If a heavy object and a light object are dropped from a height of 5 meters at the same time, and assuming no air resistance or friction, which object hits the ground first? - Heavy object - Light object - Hit the ground at the same time ## **Newton’s laws** 1. What is the definition of terminal velocity? - The maximum velocity created by the force of gravity - The maximum velocity possible on earth - The velocity of a falling object once air resistance equals the force of gravity 2. Which of these statements is correct regarding weight? - It is equivalent to mass - It is the mass of an object multiplied by the acceleration due to gravity - It is zero for an object not in motion 3. Newton’s contributions to physics includes which of the following? - Field of optics - Field of electromagnetism - Field of quantum mechanics ## **Circular motion and gravity** 1. Who is responsible for the heliocentric model of the planets? - Galileo - Copernicus - Newton 2. Centripetal acceleration is the rate of change in the velocity of the object created by a change in - Direction - Speed - Motion 3. Newton’s law of universal gravitation is based on this early astronomer’s work - Copernicus - Kepler - Galileo
