Question

_________ is a change in the position of a body with respect to time relative to a reference point.

Answer 1

Rest

Step-by-step explanation:

Rest is a change in the position of a body with respect to time relative to a reference point. The stationary state of an object or body relative to a reference position or another object is called Rest.

Taking Newton's First Law of motion into consideration, an object will remain in its state of rest or uniform motion until acted upon by an external force. This implies an object at rest is an object with zero (without) velocity and acceleration.

Answer 2

Motion

_________ is a change in the position of a body with respect to time relative to a reference point.

Step-by-step explanation:

In physics, the concept of motion describes the sudden change in the position of an object after a certain amount of time. It is understood after assimilating the concepts of speed, time, distance, displacement, and acceleration. To achieve it, certain strength has to be applied to the object and it also requires a frame of reference to be noticed.
