Here are some key points and concepts related to Mechanics that you may find useful. However, please note that these are not full notes but rather a summary of important topics. It is recommended to consult textbooks or comprehensive resources for more detailed information: Scalars and Vectors: Scalars have only magnitude (e.g., mass, temperature), while vectors have both magnitude and direction (e.g., displacement, velocity). Vectors can be represented graphically using arrows, where the l...

*Motion in a straight line refers to the movement of an object along a straight path. *This type of motion is also known as one-dimensional motion, as the object moves only along a single axis and its position can be described by a single coordinate. *The position of the object is denoted by x, and can change due to its displacement (Δx). *Velocity (v) refers to the rate of change of displacement, and can be calculated as v = Δx / Δt, where Δt is the change in time. *Acceleration (a) ref...

PHYS 1260 EXAM 4 QUESTIONS WITH CORRECT DETAILED SOLUTIONS || GUARANTEE PASS < UPDATED VERSION> Why is a larger nucleus generally less stable than a smaller nucleus? - ANSWER Because the strong force is short range, protons in a large nucleus are farther apart on average than in a small nucleus, and the strong force is less effective between wide-apart protons. length contraction - ANSWER - as objects move through spacetime, space as well as time cha...

Exercise 7.3.1 Why does the graph of a linear function have to pass through the origin? �(� + �) = �(�) + �(�) �(��) = ��(�), A linear function by definition needs to satisfy the following two conditions: Where � and � are vectors with the same number of elements and � is a scalar. �(�1, �2 … �� ) = �1�1 + �2�2 + ⋯ + ���� Thus, a linear function must be a linear combination of some number of independent variables: If (�1, �...
