GSC101: General Science Notes (pdf)
Are motion and rest absolute or related?
No, these words rest and move together. For example, a person in a car, holding a ball in his hand, will see the ball rest. While for someone else, outside the car you will see the ball moving.
how can a state of motion of a body depend upon the observer?
Consider two spectators – one on a train and the other on a plate form. The person on the train has a book next to him, and the passenger in the train rests with respect. To the viewer on the platform, the book was traveling at high speed as the train passed by. Thus, the position of the observer would determine the state of the body’s movements.
Can we say that a body is completely at rest, or a body is at absolute rest?
Think of the book on the table, though the book rests on the table but still travels the earth as it orbits its axis and orbits the sun in its orbit. Also, we know that the sun, the galaxy, and the off-course atmosphere continue, so the idea of complete or complete rest is not yet available.
Physical Quantity is one that can be defined or measured in terms of basic, acquired, or added units. The weight or length or temperature of any value can be measured, that number is known as the virtual value. The measurements remain the same (within the accuracy of the measurement system) regardless of who performs the measurements in length, location, volume, time, frequency, speed, volume, magnitude, power, electrical parameters, and magnetic field. of building materials etc.
Values do not have the same value for all viewers but depend on who makes the estimate that is, they agree, not non-physical values. Examples are values that affect emotions or happiness such as love, hate, beauty, happiness, etc.
Scalar portable quantities that do not need to be directed to be defined as 4 kg or 11 liters of milk etc. Although vectors are an apparent volume that is incomplete unless specified, such as 200N power upwards. It is worth noting that Virtual values that are already defined as vectors (weight, acceleration, speed, etc.) usually do not need to be referred to in the direction of the problem unless they change during the solution.
vector, in physics, value having both magnitude and direction. It is usually represented by an arrow whose shape is similar to that of the masses and whose length is equal to the size of a number. Although the vector has size and direction, it has no place.
