The dynamics of Newton's laws

- By Emily Richards

Magnetic force

- Magnetic forces are produced by moving electric

charges.

Electric force

- Electric force is very similar to magnetic force

and gravitational force.

Gravitational Force

- Is were there is a atmosphere on earth that we

cant see that keeps us on earth instead off

floating into outer space.

Weak interaction and nuclear force

- A nuclear forces is much stronger than any other

forces, the nuclear is what holds the atom

together in spite of the stronger electric force

repulsion between in its protons. - Also these two are found inside of the nucleus.

Newtons first law

- Galileo guessed the time of the falling bodies

but had no why of proving the speed of the bodies

that fell. For example, Galileo formed small

angles, horizontal, the speed of the rolling

balls were slow enough to measure with a water

clock. Also Galileo proved that when the balls

spead up that they improved with time.

Newtons second law

- Newtons law says that the acceleration of an

object produced by net applied force is directly

related to the magnitude of the force. For

example, the effect of a 10 newton force baseball

would much greater than the same force acting on

a truck.

Newton's third law

- The third law is a every active force were there

is an equal and a opposite reaction. Forces are

found in pairs at most times. For example, think

of a chair by the time u sit down in a chair,

your body exerts a force downward and that chair

needs to exert and equal force upward so the

chair wont collapse.

FMxA

- F ma lets us work out the forces at work on

objects by multiplying the mass of the object by

the acceleration of the object. - Example The force at work on a Formula 1 car as

it starts a race! If the F1 car has a Mass of

600kg and an Acceleration of 20m/s/s then we can

work out the Force pushing the car by

multiplyingthe Mass by the Acceleration like

this 600 x 20 12000NF ma is the second law

of motion proposed by Sir Isaac Newton.

MF/A

- When you multiply a kilogram (mass unit) times a

meter per second squared (acceleration unit) you

get a kilogram-meter per second squared. So a

unit for force is actually the kilogram-meter per

second squared. However, no one really says that.

The unit for force is named after Isaac Newton,

and it is called the 'Newton', abbreviated 'N'.

One Newton is one kilogram-meter per second

squared. Another almost identical way to think

about the force unit is that one Newton is the

size of a force needed to accelerate a mass of

one kilogram at a rate of one meter per second

squared.

AF/M

- aF/m, meaning that the amount some object

accelerates is proportional to the force on it,

and inversely proportional to the object's mass

WMxG

- Weight has dimensions of a force. On the surface

of the earth the amount of force pushing down on

a scale is W Mg where g 9.8 m/sec is the

acceleration of an object dropped at the surface

of the earth.

MW/G

- 'The response of any body - with any weight (w) -

to gravity is thesame as its resistance to

acceleration' That is the ratio of anybody's

weight (w) divided by the acceleration (g) at

which it willfreefall is equal to the ratio of

the net force (f) exerted on and/orby it,

divided by the acceleration (a) that is caused.

GW/M

- each particle of matter attracts every other

particle with a force which is directly

proportional to the product of their masses and

inversely proportional to the square of the

distance between them. In other words, the larger

a planet's mass and the closer to a planet an

object is, the stronger the force of gravity on

that object
