The dynamics of Newton's law

- ByG.Arnett

Magnetic Force

- The force between to magnets is magnetic force.
- You can feel magnetic force when you put a

positive side of a magnet to another part of the

magnet then you can feel the force that is

pushing.

Electric Force

- A electric force is a force from electricity.
- A example of electric force is when something has

electrical energy and it give a force to another

object.

Gravitational force.

- When the only force on a object is gravity it

will fall. This is also called free falling. - A example is when a apple is falling from a tree

is a gravitational force.

Weak interactions and nuclear force

- Weak interactions and nuclear forces are hard to

observe because they are formed in the nucleus.

Newton's first law.

- An object at rest stays at rest and an object in

motion stays in motion with the same speed and in

the same direction unless acted upon by an

unbalanced outside force. - A hockey puck will slide till something stops it

or it runs out of power.

Newton's second law

- The acceleration of an object as produced by a

net force is directly proportional to the

magnitude of the net force, in the same direction

as the net force, and inversely proportional to

the mass of the object.

Newton's third law

- For every action, there is an equal and opposite

reaction. - If you shoot a basketball the equal reaction

would be it going into the basket the oppisit

reaction would be it not going in.

FMA

- Force massacceleration
- Example- when pushing a car to find out how much

force there is you have to multiply the mass

times the acceleretion.

MF/A

- MASS FORCE / ACCELERATION
- A 300g cart reaches a speed of 50m/s in 20

seconds from a standing start.

AF/M

- ACCELERATIONFORCE/MASS

WMG

- WEIGHT MASS GRAVITY

MW/G

- MASS WEIGHT/ GRAVITY

GW/M

- GRAVITY WEIGHT/ MASS
