what is a frames of reference in physics?
240443
In physics, a frame of reference (or reference frame) consists of an abstract coordinate system and the set of physical reference points that uniquely fix (locate and orient) the coordinate system and standardize measurements within that frame.

The three laws of Physics refers to Newton's three laws of motion as follows: Newton's first law. Newton's second law. Newton's third law.

The absolute unit of force in the International System of Units (SI units) is Newton. It is defined as the force necessary to provide a mass of one kilogram with an acceleration of one meter per second per second. Whereas the gravitational unit of force is "kgf" or "kilogram-force" .

Reference is a relationship in which a symbol or sign (a word, for example) signifies something; the referent is the thing signified. The referent may be an actual person or object, or may be something more abstract, such as a set of actions.

A frame of reference is a complex set of assumptions and attitudes which we use to filter perceptions to create meaning. The frame can include beliefs, schemas, preferences, values, culture and other ways in which we bias our understanding and judgment.

Non moving objects on the Earth's surface are often used as reference points for local motion. All Motion is relative to a reference point. Object appears to move whether object moves, the reference point moves, or both move.

Position, velocity, and acceleration all describe the motion of an object; all three are vector quantities. In one dimension, position is given as a function of x with respect to time, x(t). ... The acceleration of an object is equal to the derivative of its velocity and describes the object's change in velocity over time.

Time of flight (ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium.

The difference between velocity and relative velocity is that velocity is measured with respect to a reference point which is relative to different point. While relative velocity is measured in a frame where the an object is either at rest or moving with respect to absolute frame.

A reference is an address that indicates where an object's variables and methods are stored. You aren't actually using objects when you assign an object to a variable or pass an object to a method as an argument. You aren't even using copies of the objects. Instead, you're using references to those objects.

Roughly speaking, the uncertainty principle (for position and momentum) states that one cannot assign exact simultaneous values to the position and momentum of a physical system. Rather, these quantities can only be determined with some characteristic “uncertainties” that cannot become arbitrarily small simultaneously.

The larger the mass of a moving object, the less readily it moves. According to Newton's second law of motion, the acceleration that the object experiences is inversely proportional to its mass, and you can calculate this acceleration from the object's change in speed over a set amount of time.

In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object's acceleration is given by the orientation of the net force acting on that object.

Stop motion animation (also called stop frame animation) is animation that is captured one frame at time, with physical objects that are moved between frames. When you play back the sequence of images rapidly, it creates the illusion of movement.

Physics is the the use of mathematics to study, model, and predict phenomena in the observable universe. Mechanics is the branch of physics which has to do with motion, mass, acceleration and force. Often, as a shorthand, mechanics is referred to as 'Newtonian Mechanics' or 'Classical Mechanics'.

Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
