Examples of rotational equilibrium problems include a beam supported at one end, a spinning top, and a rotating wheel. These problems can be solved by applying the principle of torque, which is the product of force and distance from the pivot point. To solve these problems, one must calculate the net torque acting on the object and ensure it is balanced to maintain rotational equilibrium.
Some examples of simple statics problems that can be solved using basic principles of physics include calculating the forces acting on a stationary object, determining the equilibrium of a structure under various loads, and analyzing the tension in a rope supporting a hanging mass.
Common spring problems in physics include calculating the spring constant, determining the force exerted by a spring, and analyzing the motion of objects attached to springs. These problems can be solved by applying Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position. By using this law and relevant equations, such as F -kx, where F is the force, k is the spring constant, and x is the displacement, these problems can be effectively solved.
Examples of Lenz's Law practice problems include calculating the direction of induced current in a coil when a magnet is moved towards or away from it, or determining the direction of induced current in a rotating loop within a magnetic field. These problems can be effectively solved by applying Lenz's Law, which states that the induced current will always flow in a direction that opposes the change in magnetic flux that caused it. By understanding this principle and using the right-hand rule to determine the direction of induced current, these problems can be solved accurately.
Examples of Boyle's law problems include calculating the final volume or pressure of a gas when the initial volume or pressure is changed. Charles' law problems involve determining the final temperature or volume of a gas when the initial temperature or volume is altered. These problems can be solved using the respective formulas for Boyle's and Charles' laws, which involve the relationships between pressure and volume, and temperature and volume, respectively.
Common Atwood machine physics problems involve determining the acceleration of the system and the tension in the connecting string. These problems can be solved using Newton's second law of motion and the concept of conservation of energy. By setting up equations for the forces acting on each mass and applying the principles of equilibrium and motion, the acceleration and tension in the system can be calculated.

Hardy-Weinberg problems involve calculating allele frequencies in a population to determine if it is in genetic equilibrium. Examples include calculating the frequency of homozygous dominant, heterozygous, and homozygous recessive individuals. These problems can be solved using the Hardy-Weinberg equation: p2 2pq q2 1, where p and q represent the frequencies of the two alleles in the population.
