The Dynamics of Newtons Laws

- Mikayla Peyton

Magnetic Force

- Magnetic force is large when compared to

gravitational force - A magnetic force occurs when a force is exerted

between magnetic poles - Its also a force which exist between two

electrically charged particals

Electric force

- Electric force is the most observable of all

forces. - An electric force occurs when a force is exerted

on an object.

Gravitational Force

- A gravitational force is the force of attraction

of all masses. - Its also the force that holds you to Earth

Nuclear and weak interaction forces

- Nuclear forces only occurs within the nucleus of

an atom - Scientists believe that another force exists

within the nucleus of an atom, this is called the

weak interaction force

Newtons 1st law of motion

- An object in motion stays in motion unless acted

upon by an outside force. An object at rest stays

at rest unless acted upon by an outside force. - Newtons 1st Law of Motion is also known as the

Law of Inertia - When you are riding in a car and the car stops,

you still move forward. This is because of

inertia

Newtons 2nd law of motion

- When an unbalanced force acts upon a body, the

body is then accelerated - An example of this is you and your friend are

sitting in a chair with your feet up, you push

your feet against theirs, the person with more

mass pushes with more force therefore sending the

other person faster when they push off

Newtons 3rd law of motion

- For every action there is an opposite and equal

reaction - One example of this is If a 3,000 pound car

crashes into a 5,000 car the 3,000 pound car is

more likely to have more damage

F M x a

- Force equals mass times acceleration
- If a driver pushes a car that ways 3,000 pounds

with a mass 0.5 then the force exerted is 1,500

M f/a

- Mass equals force divided by acceleration
- If an engine exerts 6.0 newtons of force, and

its placed on a cart that accelerates at 3.5,

then the mass would be 1.71

A f/m

- Acceleration equals force divided by mass
- A ball that is thrown with a force of 8 newtons,

if the mass is 4 then the acceleration of the

ball would be 2

W m x g

- Weight equals mass times gravity
- If a rock has a mass of 10, then and the amount

of gravity pulling on the rock is 2, then the

rock would way 20 poounds

M w/g

- Mass equals weight divided by gravity
- If a rock weighs 20 pounds, and the gravity

pulling on the rock is 2, then the mass would be

2.

G w/m

- Gravity equals weight divided by mass
- If a rock weighs 20 pounds, and the mass is 2

then the gravity pulling on it would be 2.
