Chapter 2 Newton\'s First Law of Motion - Inertia

Slide 3

1. ARISTOTLE ON MOTION Aristotle endeavored to comprehend movement by arrangement . Two Classes: Natural and Violent

Slide 4

Natural movement relied on upon nature of the protest. Illustrations: A rocks falls Smoke rises

Slide 5

The falling rate of a protest should be relative to its weight. Normal movement could be round (immaculate questions in flawless movement with no end).

Slide 6

Violent Pushing or pulling strengths forced movement. A few movements were hard to get it. Case: the flight of a bolt There was an ordinary condition of rest aside from divine bodies.

Slide 7

Aristotle was unchallenged for a long time. Most believed that the Earth was the focal point of everything for it was in its ordinary state. Much to their dismay that it was Texas No one could envision a compel that could move it.

Slide 8

2. COPERNICUS AND THE MOVING EARTH Sun was focus, not earth. He was reluctant to distribute on the grounds that he didn\'t generally trust it either. De Revolutionibus contacted him on the day he passed on, May 24, 15 43.

Slide 9

3. GALILEO AND THE LEANING TOWER 17 th Century researcher who upheld Copernicus. He discredited a hefty portion of Aristotle\'s thoughts. Taken a shot at falling article issue - utilized investigation.

Slide 10

4. GALILEO\'S INCLINED PLANES Knocked down Aristotle\'s push or force thoughts. Rest was not a characteristic state. The idea of inactivity was presented. Galileo is some of the time alluded to as the "father of experimentation."

Slide 11

He tried with planes. Demo - Ball and Incline Plane The adjustment in speed relied on upon the slant of the grade.

Slide 13

5. NEWTON\'S FIRST LAW OF MOTION Newton completed the topple of Aristotelian thoughts. Law 1 (Law of Inertia) Every protest proceeds in its condition of rest, or of uniform movement in a straight line, unless it is constrained to change that state by powers urged it. "In the event that you allow a protest sit unbothered, it has steady speed."

Demonstrations Demo - Weight and String Demo - Card, Cup, and Coin Demo - Swinging Rocks Demo - Coins on Elbow Demo - Table Setting Demo - Bottle, Hoop, and Chalk Demo – Lead Brick and Hammer

Slide 15

m 6. NET FORCE A drive or a mix of strengths produces changes in movement (increasing velocities). 10 N = 20 N 10 N = 10 N 10 N 0 N = 20 N 10 N 10 N

7. THE EQUILIBRIUM RULE Scales pushing up Examples of Mechanical Equilibrium: Normal up Computer setting on a table Weight down Weighing yourself on an arrangement of scales Hanging from a Tree pulling up Weight down Car stopped on a grade Normal Friction Weight down Weight down

Slide 17

The Equilibrium Rule

Slide 18

Scales pushing up Normal up Weight down Weight down 8. SUPPORT FORCE In the main case of mechanical balance the table provided a compel upward that was known as the ordinary constrain. It is a bolster constrain . Consider the second case of mechanical balance. The scales supply a bolster compel on the man.

Slide 19

9. Balance OF MOVING THINGS Equilibrium is a condition of no change. In the event that a protest moves in a straight line with no adjustment in speed, it is in balance. Cases: Driving at consistent speed Normal up Air resistance Air Resistance Force from street Weight down Terminal speed in parachuting Weight down

Slide 20

10. THE MOVING EARTH It is difficult to distinguish the movement of the earth since we are moving with it. Early science couldn\'t anticipate sufficiently expansive powers to move the earth. Could Hewitt\'s feathered creature drop down and get the worm if the Earth moves at 30 km/s? Demo - Cart and Ball Launcher Video – Snowmobile and Flare

Chapter 2 Review Questions

Slide 22

Which individual beneath is most exceptionally perceived for proposing a heliocentric universe? (an) Aristotle (b) Newton (c) Galileo (d) Copernicus

Slide 23

If a protest weighs 10 lb, what should the air resistance drive be if the question is falling and has achieved maximum speed? (a) 10 lb (b) 32 lb (c) there is no chance to get of telling without realizing what the estimation of the max speed is

Slide 24

Newton\'s idea of movement said that the characteristic condition of a question was (a) constant speed (b) constant quickening (c) constant net drive
