The Dynamics of Newtons Laws

- By Casey Frerichs

Magnetic Force

- Magnetic forces like electric forces are very

large in comparison to gravitational forces. In

fact magnetic forces are produced by moving

electric charges. Electric and magnetic forces

are very closely related. At the present time

this relationship is not completely understood.

Electric Force

- The force that appears when you push something

with your hand is an electric force. The electric

force of repulsion develops as the electrons of

an object. In the same way the force between an

automobiles tires and the road is an electric

force.

Gravitational Force

- Gravitational force is an extremely weak force in

comparison to the other forces. If two tennis

balls are held one meter apart the gravitational

force between them is only 0.00000000001 newtons.

Weak interaction and Nuclear Force

- Nuclear force is much stronger than all the other

forces. The nuclear force holds the nucleus of an

atom together in a spite of the strong force of

repulsion. There is a second force inside the

nucleus. It is called the weak interaction.

Newton's First law

- It is that an object continues to move or rest

unless it is acted upon by an outside force. An

example is throughing a ball and someone catching

it in a glove.

Newtons Second law

- Newtons second law states that when an

unbalanced force acts on a body it will

accelerate. An example is when u hit a baseball

the ball will accelerate.

Newtons Third law

- His third law is that every force is joined by an

equal and opposite force. An example is two

people pushing against each other.

FMA

- It is that force equals mass times acceleration.

An example and a car and its weight and its

acceleration

MF/A

- It is mass equals force divided by acceleration.

The force of the car and the acceleration would

get you the mass.

AF/M

- It is that the acceleration equals the force

divided by the mass. You would take the force

divided by the mass of the car to get the cars

acceleration.

WMG

- You get the weight by multiplying the mass by the

gravitational pull. You take the gravity on a car

and the mass to get the weight of the car.

MW/G

- Its that mass equals the weight divided by the

gravitational pull on an object. The mass of car

is the weight divided by the gravity.

GW/M

- It is that the gravity equals the weight divided

by the mass. To get the gravitational pull on a

car you would divide the weight by the mass of

the car.
