Electric forces & fields

Force & Fields introduction

interactions of forces

field lines

Electric, magnetic, and gravitational forces can affect the behavior interactions between objects exerting forces on each other even when the objects are not in contact

Field Lines are a visual representation of force. They show the path in which an object will be pushed or pulled when acted upon.

Electric Forces and Fields

electric forces

attraction of charges

Unlike charges attract one another ( - and +) Like charges repel (go against) one another ( + and + )

Electrically charges particles such as protons and electrons in atoms and molecules, have attractive and repulsive interactions with other charged particles.

The electric field lines point in the direction that a positive charge would accelerate if placed upon the line.

Electric force examples

To the right you will see the direction of positive charges accelerating on the field lines of electric forces.

magnetic forces & fields

Magnetic Forces & Fields

magnetic forces

magnetic fields

The area of magnetism, or magnetic influence, surrounding the magnet is known as the Magnetic Field Magnets near one another will push or pull one another depending on how their fields interact

MAGNETS HAVE TWO POLES NORTH & SOUTH Opposites Attract ( N -S) Likes Repel ( N - N) MAGNETIC North is the direction a compass needle points to, as it aligns with Earth's magnetic field

Magnetic Force & Fields

magnetic forces

magnetic fields

On a magnet, the field lines point from the north pole to the south pole This is the direction another magnet would be pulled if brought close to it

The magnetic force decreases as the distance between the magnets increase The magnetic force is the strongest inside the magnet and near the poles where the field lines come together

Magnetic Force & Fields

magnetic forces

magnetic forces conclusion

From observations, we know that two magnets exert force on one another. However, we cannot see contact between the magnets when they start pulling on one another Therefore, we use field lines thE

A compass points to TRUE NORTH (South) and TRUE SOUTH (North) of Earth Magnetic North of Earth is different than the NORTH POLE of a magnet

magnetic force examples

The image to the right shows the TRUE NORTH and TRUE SOUTH poles of Earth. Which explains why our compasses point upwards for NORTH and downwards for SOUTH

Why did the magnet break up with the fridge? It wasn’t attracted to it anymore.

gravitational force & fields

Gravitational Force & Fields

GRAVITATIONAL fORCE

GRAVITATIONAL Force

Gravitational forces are always attractive between two objects, but these forces are much weaker than electric force

Objects with mass are sources of gravitational fields and are affected by the gravitational fields of all other objects with mass

Gravitational Force & Fields

GRAVITATIONAL force

GRAVITATIONAL Field

Gravitational force extends across the space between two masses, but it is minimal except when one or both objects have a vast mass

A gravitational field is the force field that exists in the space around every mass or group of masses. This field extends out in all directions, but the magnitude of the gravitational force decreases as the distance from the object increase

Gravitational Force & Fields

GRAVITATIONAL force - large scale systems

For large-scale systems in space, such as galaxies, the solar system, or Earth and Sun, long-range gravitational forces determine the movement patterns within those systems.

gravitational force examples

Take a look at the image to see an eample of a large-scale system gravitational force exertion in space
