8PS2.1 and 2.2 Study Practice

The field becomes weaker

The field becomes stronger

The field changes into a contact force

The field disappears immediately

A wire that carries electric charge

A solid material attached to an object

A region around an object where forces can act

A force that only exists during a collision

The source object must be moving

The objects must always be touching

The field must be visible to the eye

A second object must interact with the field

To create gravity around a magnet

To block all field lines

To remove a field from a region

To provide evidence about properties of a field

The temperature of the surrounding air

The mass of the source charge only

The color of the electric field

The field's direction at that location

Moving them closer together

Separating them farther apart

Removing both charges from the area

Replacing the charges with uncharged objects

A charged object may attract or repel another object

Every charged object repels every other object

Charges interact only when they touch

Charges cannot produce fields in empty space

A force requires another object to interact with the field

Fields have mass but no direction

A field can exist only inside a conductor

Strength is measured only for touching objects

They are visual models of field strength and direction

They are visible only when a battery is connected

They are solid wires found around magnets

They are particles that carry electric current

The field can still exist even when no object is interacting with it

The field is created by the test object instead

The field exists only if a compass is present

The field changes into an electric current
