Chapter 2 Lesson 1 physics

is a series of images of a moving object that records its position after equal time intervals.

• particle model

• operational definition

• motion diagram

• association

is a series of points of a moving object that records its position after equal time intervals

• particle model

• operational definition

• motion diagram

• association

In the particle model, the ........ of the object is ignored

• acceleration

• position

• motion diagram

• internal motions

A motion diagram is a series of images of a moving object that records its position after

• 1/30 s

• equal time intervals

• it comes to rest

• an acceleration

When an object moves in the opposite direction.

• Its negative position

• Its positive position

• Its constant

What are the two components used to define motion?

• time

• distance

• displacement

• image

What is the purpose of drawing a motion diagram or a particle model?

• to calculate the speed of the object in motion

• to calculate the distance covered by the object in a particular time

• to check whether an object is in motion

• to calculate the instantaneous velocity of the object in motion
