Flashcards in Lesson 3: Newton's Laws of Motion Deck (12):
1

a change in an object's position over time

motion

2

the object the appears to stay in place when comparing to see if something is moving

reference point

3

the measure of the distance of an object in a given amount of time

speed

4

a quantity that describes the speed of an object and its direction of travel

velocity

5

the rate at which velocity changes

acceleration

6

Newton's first law is sometimes called the

law of inertia

7

the tendency of objects to resist any change in motion

inertia

8

when the force increases, acceleration of an object with constant mass increases with the same amount of the force, so it is

directly proportional

9

Since acceleration increases when mass increases, it is

inversely proportional

10

Newton's third law is sometimes called

action and reaction forces

11

the force of attraction between objects due to their masses

gravity

12

a set of objects that are all stationary with respect to each other

reference frame
