The dynamics of Newton's Laws

- By Landen Holder

Magnetic force

- Magnetic forces are produced by moving electrical

forces - Magnetic and electrical forces are very close

related

Electric force

- An electric force is produced when you push

something - The electric force of repulsion develops when the

electrons in your hand are brought close to the

electrons of an object

Gravitational force

- Gravitational force is extremely weak compared

tot the other forces - Gravitational force is when an object is

attracted to another larger object

Weak interaction and nuclear force

- Nuclear forces are much stronger than any of the

other forces - This force holds together the nucleus of an atom
- Scientists believe that a force exists inside the

nucleus of atoms called weak interaction - It is believed to be the force that causes atoms

to break apart

Newton's first law

- Newton's first law states that an object in

motion will stay in motion and an object at rest

will stay at rest unless acted upon by an outside

force - Throw a baseball and someone catches it to stop it

Newton's second law

- A force on an object will move the object in the

direction of the force - An example of this is a person hitting a golf

ball with a golf club and the ball traveling in

the direction of the club

Newton's third law

- Every action has an equal and opposite reaction
- An example of this would be a rocket taking off.

The force is the blast of ignited fuel and the

reaction is the rocket shooting upwards

F M x A

- This formula means that force equals the mass

times the acceleration of an object - This means that if a car has a mass of 1000 N and

it is accelerating by 20 N its force would be

20,000 N

M F / A

- This formula means that mass is equal to force of

an object divided by its acceleration - An example is a football with a force of 50 N and

its traveling at 10 N its mass is 5 N

A F / M

- This formula means that an objects acceleration

can be found by dividing its force by its mass - An example is if a car has a force of 600 N and

its mass is 200 N its acceleration is 3 N

W M x G

- This means that weight is equal to the mass of an

object multiplied by the gravitational force

acting on it - For example is a vehicles mass is 25 N and their

gravitational pull from the Earth is 30 N their

weight is 750 N

M W / G

- This means that an objects mass is equal to the

weight of an object divided by its gravitational

pull - For example if a car weighs 100 N and has a

gravitational pull of 10 N its mass is 10 N

G W / M

- This formula means that the gravitational pull on

an object is equal to its weight divided by its

mass - For example if a car has a weight of 25 N and its

mass is 5 N its gravitational pull on the car is

5 N
