Could someone please explain the Laws of Issac Newton and the basics of Force?!?!?!?

Question

I need like "Issac Newton and Force for Dummies" kinds of crap.. I've got a test tomorrow and when it comes to Science, I'm completely clueless!!! I also need the equivalent of one Newton and the formulas for conversion.

THANKS TO WHOEVER ANSWERS CORRECTLY!!!!

BTW, I think someone said there are three laws...

Answer 1

1st law
An object is either at rest or travelling at a constant velocity, unless an unbalanced force acts on it
(or - kick it, and it moves)

2nd law
The rate of change of momentum is equal to the unbalanced force; F=ma
(or - kick it harder, it moves more)

3rd law
For every action, there is an equal and opposite reaction
(or - kick it, and it kicks back)

Answer 2

First Law
Objects in motion tend to stay in motion, and objects at rest tend to stay at rest unless an outside force acts upon them.

Second law
The rate of change of the momentum of a body is directly proportional to the net force acting on it, and the direction of the change in momentum takes place in the direction of the net force.

Third law
To every action (force applied) there is an equal but opposite reaction (equal force applied in the opposite direction).

Answer 3

NEWTON'S FIRST LAW
any object in a state of rest or motion resists any change in its state.(i.e ........if a body is moving it will resist when u try to stop it and any body in rest will resist when u try to move it )
NEWTON;S SECOND LAW
the force experienced by a body is equal to the product of the mass and accelaration of the body .
NEWTON;S THIRD LAW
every action has an equal and opposite reaction
(example.........when u try to compress a spring.........it will try to regain its original shape when u leave it ..........this is due to the restoring force in the spring ..........and the restoring force is of equal magnitude ad tat of the force applied by u .but in opposite direction)
1 newton is defined as tat force which has to be applied to accelarate a body of mass 1 kg by 1 m\s^2.
1 newton=1kg*1m/s^2[SI system]
i dyne=1gram*1cm/s^2[CGS system]


hope this helps !!

Answer 4

For every action, there is an equal and opposite reaction.

Answer 5

and how exactly will you know if they have answered correctly???
