Kinematics is the study of the motion of objects without considering the forces that cause the motion. On the other hand, dynamics is the study of the forces that cause the motion of objects. In other words, kinematics is concerned with the "what" of motion, while dynamics is concerned with the "why."
The key to improving your problem-solving skills in physics is practice. Start by understanding the fundamental concepts and principles, and then work your way up to more complex problems. It is also helpful to break down the problem into smaller, more manageable steps and to use diagrams and equations to visualize and organize the information.
One common mistake is not properly understanding the problem and rushing to find a solution. It is important to carefully read and analyze the information given in the problem before attempting to solve it. Another mistake is not showing all the steps and skipping important details. It's important to clearly explain your thought process and show all the calculations and equations used.
Real-life examples can help make abstract concepts in physics more tangible and relatable. You can look for everyday situations that demonstrate the principles you are learning, such as using the equations for projectile motion to predict the trajectory of a thrown ball. You can also search for videos or simulations that illustrate physics concepts in action.
There are various resources available for getting help with physics problems, such as textbooks, online tutorials and videos, study groups, and tutoring services. Your teacher or professor can also provide guidance and clarification on specific problems. It's important to find a resource that works best for your learning style and to ask for help when needed.
