Newton’s Laws of Motion (Ch 5)

•Isaac Newton

•1642-1727

•English physicist &

mathematician

•By the age of 31, discovered:

•laws of motion

•universal gravitation

•calculus

•Eccentric

•read Coming of Age in the

Milky Way, by Timothy

Ferris

Force

A force is a push or pull. An

object at rest needs a force to

get it moving; a moving object

needs a force to change its

velocity.

The magnitude of a force can

be measured using a spring

scale.

Newton’s First Law of Motion

Newton’s first law is

often called the law of

inertia.

An object in motion

stays in motion and an

object at rest stays at

rest, unless acted upon

by a force.

Newton’s First Law

Every object continues in its state of rest, or of

uniform velocity in a straight line, as long as

no net force acts on it.

Newton’s First Law of Motion

Inertial reference frames:

An inertial reference frame is one in which

Newton’s first law is valid.

This excludes rotating and accelerating frames.

ConcepTest

A book is lying at rest on a table. The book will

remain there at rest because:

1) there is a net force but the book has too much inertia

2) there are no forces acting on it at all

3) it does move, but too slowly to be seen

4) there is no net force on the book

5) there is a net force, but the book is too heavy to

move

ConcepTest

A hockey puck slides on ice at constant

velocity. What is the net force acting on the

puck?

more than its weight
equal to its weight
less than its weight but more than zero
depends on the speed of the puck
zero

ConcepTest

You put your book on the bus seat next to

you. When the bus stops suddenly, the book

slides forward off the seat. Why?

1) a net force acted on it

2) no net force acted on it

3) it remained at rest

4) it did not move, but only seemed to

5) gravity briefly stopped acting on it

ConcepTest

From rest, we step on the gas of our Ferrari,

providing a force F for 4 secs , speeding it up to a

final speed v. If the applied force were only 1/2 F ,

how long would it have to be applied to reach the

same final speed?

16 s
8 s
4 s
2 s
1 s

ConcepTest

A force F acts on mass m 1 giving acceleration a 1. The same force acts on a different mass m 2 giving acceleration a 2 = 2 a 1. If m 1 and m 2 are glued together and the same force F acts on this combination, what is the resulting acceleration?

3/4 a 1
3/2 a 1
1/2 a 1
4/3 a 1
2/3 a 1 F m^1 a 1 F m^2 m^1 a 3

F

a 2 = 2 a 1 m 2

ConcepTest

What can you say about the acceleration of gravity acting on a stone and a feather?

it is greater on the feather
it is greater on the stone
it is zero on both due to vacuum
it is equal on both always
it is zero on both always

ConcepTest

What can you say about the force of gravity Fg acting on a stone and a feather?

Fg is greater on the feather
Fg is greater on the stone
Fg is zero on both due to vacuum
Fg is equal on both always
Fg is zero on both always

Newton’s Third Law of Motion

Any time a force is exerted on

an object, that force is caused

by another object.

Newton’s third law:

Whenever one object exerts a

force on a second object, the

second exerts an equal force in

the opposite direction on the

first.

More traditionally

• For every action, there is an equal and

opposite reaction.

Newton’s Third Law of Motion

application of the third
