College Physics is a comprehensive textbook that guides students through the fundamental principles of physics, starting from classical mechanics and progressing to modern theories. The book builds a solid foundation with chapters on kinematics, Newtonian mechanics, and energy conservation before expanding into topics like fluid dynamics, thermodynamics, and wave optics. As the material advances, readers explore the dual nature of light, electromagnetism, and the revolutionary ideas of special relativity and quantum mechanics. With practical examples, diagrams, and problem-solving strategies integrated throughout, the text effectively connects theoretical concepts to real-world applications, preparing students for a deeper understanding of the physical universe.

Problem 1
In Figure $\mathbf{P} 2.1$ you see unlabeled force diagrams for balls in different situations. Match the diagrams with the following descriptions. (1) A ball is moving upward after it leaves your hand. ( 2 ) You hold a ball in your hand. (3) A ball is falling down. (4) You are throwing a ball (still in your hand) straight up. (5) You are lifting a ball at a constant pace. Explain your choices. Label the forces on the diagrams.

Problem 3
Determine the torques about the axis of rotation $P$ produced by each of the four forces shown in Figure $P 7.1$ . All forces have magnitudes of 120 N and are exerted a distance of 2.0 $\mathrm{m}$ from $P$ on some unshown object O.

Problem 4
Determine the $x$ - and $y$ -components of each force vector shown in Figure P3.2.
Problem 5
A uranium nucleus has 92 protons. (a) Determine the magnitude of the $\vec{E}$ field at a distance of $0.58 \times 10^{-12} \mathrm{m}$ from the nucleus (about the radius of the innermost electron orbit around the nucleus). (b) What is the magnitude of the force exerted on an electron by this $\vec{E}$ field? (c) What assumptions did you make? If the assumptions are not valid, will the magnitude in part (b) be an overestimate or underestimate of the actual value?

Problem 6
A car starts at rest from a stoplight and speeds up. It then moves at constant speed for a while. Then it slows down until reaching the next stoplight. Represent the motion with a motion diagram as seen by the observer on the ground.
