The type of forces we have learned about means they do not need to touch to affect the field around them. This is called:

• non-contact

• neutral

• north/south pole reversation

• invisible forces surrounding objects

A field is defined as:

• repulsion of forces

• noticeable pull between two objects

• invisible and extends through space

In magnetic forces we know that the following is true:

• N/S poles repel while two like poles attract

• N/S poles attract while two like poles repel

Gravitational forces affect anything with:

• charges

• mass

• gravity

• sweaters

Electric Fields act not on a force for themselves but:

• a force on others

• on like charges

• on gravity

• on light switches

NGSS.MS-PS2-5

In our experiment with magnets we could feel the force of:

• North pole vs south pole

• positive and negatives

• attraction and repulsion

NGSS.MS-PS2-3

NGSS.MS-PS2-5

This is a gravitational force

• weight

• mass

• pounds

• scales

Tags

NGSS.MS-PS2-4

NGSS.MS-PS2-5

This force increases with mass, decreases with distance, and points towards the center of the object

• Reverse magnetic electrical forces

• Electrical Force

• Magnetic Force

• Gravitational Force
