1 Force motion examples.notebook April 07, 2015 MOTION AND FORCES GRAVITY: a force that makes any object pull toward another object Feb 15 12:00 PM 1

2 FRICTION: a force that acts to slow down moving objects Feb 15 12:06 PM 2

3 FORCE: push, pull, or twist that makes something move PULL Stretching springs 3

4 PUSH Bulldozers 4

5 TWIST Twisting 5

6 MASS: amount of matter in an object WEIGHT: this measure describes the amount of gravitational force of an object Mass and weight example 2 6

7 Feb 15 12:16 PM 7

8 First Law of Motion states that: an object at rest tends to stay at rest and an object in motion tends to stay in motion Inertia: the tendency of an object to remain at rest if at rest or to continue moving if in motion. Feb 15 12:23 PM 8

9 Second Law of Motion states that: acceleration is produced when a force acts on a mass. ACCELERATION: rate at which an object changes its velocity SPEED: distance covered within a certain unit of time VELOCITY: rate at which an object is traveling in a certain direction Feb 15 12:23 PM 9

10 Third Law of Motion states that: for every action, there is a separate but equal reaction. That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard. Let's study how a rocket works to understand Newton's Third Law. The rocket's action is to push down on the ground with the force of its powerful engines, and the reaction is that the ground pushes the rocket upwards with an equal force. Feb 15 12:23 PM 10

11 MOMENTUM: product of an object's mass and its velocity Feb 15 12:26 PM 11

12 Feb 15 12:43 PM 12

13 NEWTON: This English scientist first described mathematically the force of gravity NEWTON: unit of measurement Einstein: German born scientist who formulated a more accurate theory involving the force of gravity Feb 15 12:36 PM 13

14 STATE OF MOTION: describe an objects velocity or speed with a direction EQUILIBRIUM: all forces acting upon an object balancing each other, the object will be in this state Feb 15 12:40 PM 14

15 GRAVITY: a force that makes any object pull toward another object FRICTION: a force that acts to slow down moving objects FORCE: push, pull, or twist that makes something move MASS: amount of matter in an object WEIGHT: this measure describes the amount of gravitational force of an object MASS: amount of matter in an object First Law of Motion states that: an object at rest tends to stay at rest and an object in motion tends to stay in motion Inertia: the tendency of an object to remain at rest if at rest or to continue moving if in motion. Feb 15 12:53 PM 15

16 Second Law of Motion states that: acceleration is produced when a force acts on a a mass. ACCELERATION: rate at which an object changes its velocity SPEED: distance covered within a certain unit of time VELOCITY: rate at which an object is traveling in a certain direction Third Law of Motion states that: MASS: for every amount action, of there matter is a in separate an object but equal reaction.
