The dynamics of Newton's laws

Magnetic Force

- Magnetic forces are produced by moving electric

charges.

Electric Force

- The force that appears when you push on

something with your hands is electric force. This

electric force of repulsion develops as the

electrons of the hand are brought close to the

electrons of an object.

Gravitational Force

- Gravitational force is an extremely weak force

in comparison to the other forces.

Weak Interaction and Nuclear Forces

- Nuclear forces are much stronger than other

forces. The nuclear force holds the nucleus of an

atom together in spite of the strong electric

force of repulsion between its protons.

Newton's first law

- His first law of motion states, A body

continues in its state of rest, or of uniform

motion in a straight line, unless it is acted

upon by a net external force.

Newton's second law

- the second law says that the acceleration of an

object produced by a net applied force is

directly related to the magnitude of the force,

the same direction as the force, and inversely

related to the mass of an object.

Newton's third law

- The third law says that for every action there

is an equal and opposite reaction. Forces are

found in pairs.

FMxA

- The more force the more acceleration. F force,

A acceleration, M mass.

M F/A

- m mass, f force, a acceleration

AF/M

- A acceleration, F Force, M mass. This means

acceleration equals force divided by mass.

W MxG

- W means weight, M means mass and G means

gravity. This means weight equals mass multiplied

by gravity.

M W/G

- M means mass, W means weight, and G means

gravity. This means that mass equals weight

divided by gravity.
