The Dynamics of Newtons Laws

- By Ryan Thomas

Magnetic Force

- Magnetic forces are very large in comparison to

gravitational forces. Magnetic forces are caused

by moving electrical charges. Magnetic and

electric forces are very closely related.

Electric Force

- The force that appears when you push on something

with your hand is an 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. If two tennis

balls are held one meter apart, the gravitational

force between them is only 0.00000000001 newtons.

Weak Interaction Nuclear Force

- Nuclear forces are much stronger than any of the

other forces. The nuclear force holds the nucleus

of an atom together in spite of the strong

electric force of repulsion between its protons. - The second force inside a nucleus is the weak

interaction force. This is the force believed to

break some atoms apart.

Newtons 1st Law of Motion

- A body continues in its state of rest, or of

uniform motion in a straight line, unless its

acted upon by a net eternal force. - Example When youre riding in a car and the car

stops your body lunges forward because it wants

to continue moving.

Newtons 2nd Law of Motion

- When an unbalanced force acts on a body, the body

will be accelerating. - Example when you hit a golf ball is hit by a

golf club the ball goes in the direction you hit

the ball.

Newtons 3rd Law of Motion

- Every force is accompanied by an equal and

opposite force. - Example When you hit a baseball with a baseball

bat, the ball goes further than the ball because

you hit the ball with more force than the ball

had.

FMA

- This means that force equals mass times

acceleration. - Example The force that was exerted on the car is

found by multiplying the cars mass times the

acceleration it has.

M F/A

- This means mass equals force divided by

acceleration. - Example The mass of a car is found by dividing

the force exerted on the by the acceleration of

the car.

A F/M

- This means that acceleration equals force divided

by mass. - Example The acceleration of a car is found by

dividing the force exerted on the car by the mass

of the car.

W MG

- This means that weight equals mass times

gravitational pull. - Example Your weight is found by multiplying your

mass by your gravitational pull.

M W/G

- Mass is found by dividing your weight by your

gravitational pull. - Example Your mass is found by dividing your

weight by your gravitational pull.

G W/M

- Gravitational pull equals weight divided by mass.
- Example Your gravitational pull is found by

dividing your weight by your mass.
