Question

URGENT! Please give the correct answer.

Describe motion in terms of frame of reference, displacement, time, and velocity. Elaborate.

Answer 1

In physics, motion is the phenomenon in which an object changes its position with respect to time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed and frame of reference to an observer and measuring the change in position of the body relative to that frame with change in time.

Answer 2

Step-by-step explanation:

In order to describe motion, a frame of reference needs to be established. All measurements are made relative to this frame of reference. A frame of reference commonly is stationary, but can also be moving. For example, if a car is moving relative to a person standing on a sidewalk, the point where the person is standing is the (0,0) of the coordinate system. All measurements then are based on that point of origin.

Displacement is a vector, meaning it has magnitude and direction. It is the straight-line distance (regardless of path taken) of an object or point from the point of origin, with direction indicated.

Velocity is the change in displacement per unit time, therefore velocity is a vector, having both magnitude and direction. Velocity is the rate of change of displacement.
