The Dynamics of Newtons Law

- By Preston Crump

Magnetic Force

- Magnetic forces are produced by moving

electrical charges. - Magnetic and electric forces are very closely

related.

Electric forces

- The force that appears when you push something is

electric force. - This type of force develops as electrons of the

hand is brought close to the electrons of an

object.

Gravitational force

- This type of force is extremely weak compared to

the other forces. - This force happens when things fall.

Weak interaction and nuclear

- Nuclear force is much stronger than any other

force. This force holds together the nucleus of

an atom together. - Scientists believe that a second force exists in

the nuclei of an atom. Weak interaction is

believed to be the force that breaks atoms apart.

Newtons first law

- Newtons first states that and object in motion

will stay in motion and an object at rest will

stay at rest unless an outside force is acted

upon it. - If you were to throw a ball the ball would keep

going until friction in the air stops it.

Newtons second law

- Newtons second law states that when an

unbalanced force acts upon a body the body will

accelerated. - For example if you were to hit a ball the ball

would go in the direction that the objects force

is going

Newtons third law

- Newtons third law states that for every action

there is an equal and opposite reaction. - For example when you shoot a gun the gun will

shoot but also push back on you in the form of

recoil.

Fma

- Force is equal to the mass times the acceleration

of an object. - That means that if a car mass of 1000 N and it

is accelerating by 20 N its force would be 2O,OOO.

Mf/a

- This formula means that mass is equal to the

force of an object divided by its acceleration. - An example of this is if a car has a force of

2000 N and an acceleration of 40 N its mass would

be 50

Af/m

- This means that an objects acceleration can be

found by dividing its force by its mass. - For example if a car has a force of 100 N and a

mass of 10 N its acceleration would be 10 N

Wmg

- This formula states that an objects weight can be

found by dividing its mass by its gravitational

pull - For example if a car has a mass of 100 N and a

gravitational pull of 10 N then its weight would

be 10 N.

MW/G

- This means that an objects mass is equal to the

weight of an object divided by its gravitational

pull. - For example if a car weighs 100 N and has a

gravitational pull of 5 N its mass is 20.

G w/m

- This formula means that an objects gravitational

pull is equal to its weight divided by its mass. - For example if a car has a weight of 100 N and a

mass of 10 N its gravitational pull is 10 N.
