According to the text, Newton's laws are often stated in terms of point or particle masses because

internal parts of real bodies can be neglected

the separation between bodies is much larger than their size

real bodies have negligible volume

real bodies can be approximated as pointlike (correct)

In the context of motion, what does it mean for a body to have a one-dimensional motion?

The body can only move in a circular path

The body can move in any direction

The body can only move in a straight line (correct)

The body can move in multiple dimensions

The mathematical description of motion, or kinematics, is based on the idea of

representing movement using numbers

assigning values to each position coordinate

using a time variable to represent a body's trajectory

specifying positions using numerical coordinates (correct)
