The dynamics of Newtons laws.

- By B.Patrick

Magnetic force

- Magnetic forces are produced with magnets, and

Electrical charges. - Electrical and magnetic forces are closely

related to each other, and still to this day it

is not completely understood. - Example A rocket having a magnet in front of it

and behind it.

Electric forces

- Electric force is when you push on something with

your hand. - This force of repulsion develops as electrons.
- Example You knock over one domino then that

domino hits another then it goes on and on till

all of the dominos are knocked over.

Gravitational force

- Gravitational force is the weakest force that we

can see. - If two tennis balls are held 1 meter apart then

the gravitational pull would be 0.00000000001

Newton's. - Example Dropping a book on the floor.

Weak interaction and nuclear force

- Nuclear forces are the strongest forces, but they

are so small that we cant see it happen. - This force holds the nucleus of atoms together.

Newton's first law of motion

- Newton's first law of motion stats that an object

in motion will stay in motion and an object at

rest will stay at rest until acted upon by an

outside force. - Example you drive a car and then you stop and

your body keeps going.

Newtons seconded law of motion

- Newtons seconded law of motion states that the

acceleration of an object produced by a net

applied force is directly related to the

magnitude of the force. - Example you role a ball and there are two forces

acting on it gravity and friction.

Newtons third law of motion

- Newtons third law of motion states that for

every action there is an opposite but equal

reaction. - Example A rocket going up into outer space using

thrusters.

F(m)A

- The mass of an object times acceleration of an

object will equal the force of the object. - Example a car moving 60 miles per hour weighs

200,000 pounds. 60 200,000 the force.

M F/A

- The force of an object divided by the

acceleration of an object equals the mass of the

object. - Example a car hits a wall traveling 40 miles per

hour with a force of 3,000 psi (pounds per square

inch). 403000

A F/M

- Force divided by mass equals acceleration.
- Example if the force is 20 and the mass is 5

then the acceleration is 4.

W MG

- This formula is weight equals mass times gravity.
- If the mass of an object is 20 and the

gravitational pull is .5 then the weight is 10

MW/G

- This formula is mass equals weight divided by

gravity . - Example if gravity is .5 and the weight is 50

then the mass is 100

GW/M

- This formula is gravity equals weight divided by

mass. - Example if the weight is 50 and the mass is 200

then the gravitational pull is 4.
