The Dynamics of Newtons Laws

- By Hayden Holley

Magnetic Force

- Magnetic forces are produced by moving electric

charges - Positive to negative attract
- Negative to negative repels
- Positive to positive repels
- Ex On a rollercoaster there is a positive magnet

on the car and there is a negative magnet on the

track which causes it to attract.

Electric Force

- The force that appears when you push on something

with your hands. - This appears when the electrons of the hand is

brought close to the electrons of an object. - When two objects come in contact.
- Ex When you high five somebody its an electronic

force.

Gravitational Force

- Gravitational forces is an extremely week for

compared to the other forces. - Ex Two tennis balls are held to one meter

apart, the gravitational force between them are

0.00000000001 newton's the forces in the other

hand can be way great such as 500 000 000 000 000

000 000 newton's.

Weak interactions and nuclear force

- Nuclear forces are much stronger than any other

force. - Weak interactions is the force that cause some

atoms to break down. - But neither of them are observable because their

in the nucleus.

Newtons First Law

- An object at rest must stay at rest until a force

is acted upon it. - An object in motion will stay in motion until a

force is acted upon it. - Ex When your in a car, it will keep moving until

a force is acted upon it such as the breaks.

Newtons Second Law.

- If you exert the same force on two objects of

different mass, you will get different

accelerations. - Ex A soccer ball and a basketball are dropped

from a building, the acceleration of one of the

balls is going to be faster than the other.

Newtons Third Law

- For every action there is an equal and opposite

reaction. - Ex If you throw a heavy ball or block away from

your body, the force exerted will push back on

you, possibly pushing you backward onto the

ground.

F M x A

- Force equals mass times acceleration
- F force
- M mass
- A acceleration
- Ex 50 10 x 5

M F/A

- Mass equals force divided by acceleration
- M mass
- F force
- A acceleration
- Ex 4 3/12

A F/M

- Acceleration equals force divided by mass
- A acceleration
- F force
- M mass
- Ex 20 5/100

W M x G

- Weight equals mass times gravity
- W weight
- M mass
- G gravity
- Ex 12 4 x 3

M W/G

- Mass equals weight divided by gravity
- M mass
- W weight
- G gravity
- Ex 5 10/2

G W/M

- Gravity equals weight divided by mass
- G gravity
- W weight
- M mass
- Ex 5 4/20
