The Dynamics of Newtons Laws

- By Hayden Chism

Electric Force

- This is the force that appears when you push

something. - This electric force of repulsion develops as

electrons of the hand are brought close to the

electrons of an object.

Gravitational Force

- The force the pulls two objects together
- This force is extremely weak in comparison to

others

Weak Interactions and Nuclear Force

- The force that holds the nucleus of an atom

together is the nuclear force. - Weak interactions is the force that causes some

atoms to break apart.

Newtons First Law of Motion

- A body continues in its state of rest, or of

uniform motion in a straight line, unless acted

upon by a net external force. - This like how a baseball stays at rest until

thrown by someone, and it stays in motion until

it hits the glove.

Newtons Second Law of Motion

- When an unbalanced force acts on a body, the body

will be accelerated. - This is like how a kid kicks a soccer ball, so

the ball accelerates.

Newtons Third Law of Motion

- Every force is accompanied by an equal and

opposite reaction. - This is like how a air rushes a balloon and

causes the balloon to go up into the air.

FMA

- This means that force is equal to the product of

an objects acceleration and mass. - If a bus is accelerating at 5 mph and its mass

is 1000 kilograms, then the force needed to push

it is 5000 N.

MF/A

- This means that mass is equal to force divided by

acceleration. - If someone is pushing a bus with a force of 1000

N and its accelerating at a rate 10 mph, the

mass is 100 kilograms.

AF/M

- This formula means that acceleration equals an

objects mass divided by its mass. - If a football is thrown with a force of 1000N and

its mass is 50 kilograms, then its acceleration

is equal to 20 mph.

WMG

- This means than weight is equal to the product of

an objects mass and the amount of gravity acting

upon it. - If an object has a mass of 1000 kilograms and the

amount of gravity acting on it is 40 N, then the

weight of the object is 40,000 N.

MW/G

- This means that mas is equal to an objects

weight divided by the amount of gravity acted on

it. - If an objects weight is 500 N and the amount of

gravity acting on it is 100N, then the objects

mass would be 5 kilograms

GW/M

- This means that the amount of gravity acting on

an object is equal to its weight dived by its

mass. - An object that has a weight of 700 N and has a

mass of 70 kilograms, then the amount gravity

acting on it is 100 N.
