AP Physics Unit 1 Progress Check MCQ Rock X is released from rest at the top of a cliff that is on Earth. A short time later, Rock Y is released from rest from the same location as Rock X. Both rocks fall for several seconds before landing on the ground directly below the cliff. Frictional forces are considered to be negligible. Which of the following graphs best represents the vertical displacement of Rock X as a function of time starting from immediately after the rock is released from rest? T...

Physics 180A Final Exam |True or False| Exam Elaboration [Graded A+] A large crate is at rest on a horizontal floor. A person exerts a horizontal force on the box, but the crate remains at rest. Therefore, the force exerted by the person on the crate and the force of static friction that the floor exerted on the crate form an action reaction pair. *Ans* False If an object of mass 50kg is traveling with a constant velocity of magnitude 10m/s then the net force on this object must be z...

How do inclined planes work? An inclined plane allows you to exert your input force over a longer distance. As a result, the input force needed is less than the output force. Simple Machine Is the most basic device for making work easier. What are 3 closely related simple machines from the inclined plane family? Inclined plane Wedge Screw What is a ramp an example of? A ramp is an example of a simple machine called an inclined plane. Inclined Plane Is a flat, s...
