1.1/1.2 Motion Diagrams/Models and Modeling

Question 1

Motion+the 4 types

Answer 1

The change of an object’s position with time

Linear, circular, projectile, rotational

Question 2

Translational motion +ex

Answer 2

The object moves through space
Linear. circular and projectile motion

Question 3

Trajectory

Answer 3

The path along which the object moves, whether straight or curved

Question 4

Why is rotational motion somewhat different?

Answer 4

Theres movement but the object as a whole doesn’t change position

Question 5

Motion diagram

Answer 5

Edited image that shows an object’s position at several equally spaced instants of time

Question 6

Model+ex

Answer 6

a highly simplified picture of reality but one that still captures the essence of what we want to study

Mass on spring for all oscillating systems is an ex

Question 7

Particle (2)

Answer 7

An object that can be represented as a mass at a single point in space

-has no size, shape and no distinction between top and bottom or between front and back

Question 8

The particle model (2)

Answer 8

a simplification in which we treat a moving object as if all of its mass were concentrated at a single point

excellence approximation of reality for the translational motion of cars, planes, rockets and similar objects

Question 9

frame in motion diagram

Answer 9

Each separate image at a fixed rate
