Conceptual Physical Science Study Guide Chapter 1 Part 1 Question 1 A probe in space continues in its motion due to its own inertia Question 2 A push on a 1-kg brick accelerates the brick. Neglecting friction, to equally accelerate a 10-kg brick requires the force to be 10 times as much Question 3 A ball tossed vertically upward reaches its highest point and then falls back to its starting point. During this up-and-down motion the acceleration of the ball is always directed downward Question 4 The force required to maintain an object at a constant velocity in free space is equal to zero Question 5 A kilogram is a unit of mass Question 6 A 10-kg mass at Earth's surface weighs about 100N Question 7 Compared with a 1-kg block of solid iron, a 2-kg block of solid iron has the same none of the above (mass, volume, weight) Question 8 In a dream you're in a car traveling at 50 km/h and you bump into another car traveling toward you at 48 km/h. The speed of impact is 98 km/h Question 9

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
