the continuous change in position of an object relative to a point of reference is?
Weegy: In physics, motion means a change in the location of a body. Change in motion is the result of applied force. [ Motion is typically described in terms of velocity, acceleration, displacement, and time.[1] An object's velocity cannot change unless it is acted upon by a force, as described by Newton's first law also known as Inertia. An object's momentum is directly related to the object's mass and velocity, and the total momentum of all objects in a closed system (one not affected by external forces) does not change with time, as described by the law of conservation of momentum. A body which does not move is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position. Motion is always observed and measured relative to a frame of reference. As there is no absolute reference frame, absolute motion cannot be determined; this is emphasised by the term relative motion.[2] A body which is motionless relative to a given reference frame, moves relative to infinitely many other frames. Thus, everything in the universe is moving.[3] More generally, the term motion signifies any spatial and/or temporal change in a physical system. For example, one can talk about motion of a wave or a quantum particle (or any other field) where the concept location does not apply ] (More)

according to newton's first law of motion for every action there is an equal and opposite reaction? true or false
Weegy: False. Whenever a particle A exerts a force on another particle B, B simultaneously exerts a force on A with the same magnitude in the opposite direction. The strong form of the law further postulates that these two forces act along the same line. [ This law is often simplified into the sentence, "To every action there is an equal and opposite reaction." ] User: according to newton's first law the acceleration of an object is directly proportional to its mass? true or false Weegy: True .According to Newton's second law, the acceleration of an object depends on its MASS and the amount of FORCE applied to it.
