SBA Revision: Forces, Circuits, and Resistance

A set of review flashcards covering non-contact and contact forces, factors affecting forces, series and parallel circuits, and electric resistance based on lecture notes.

What defines non-contact (field) forces, and what examples are provided in the notes?

Non-contact forces involve no physical contact, with examples including gravitational and electrostatic forces.

What defines contact forces, and what examples are listed in the notes?

Contact forces occur when objects are touching, with examples including friction and tension.

What three factors affect forces according to the revision notes?

Size/Mass, Distance, and Weight.

What value is listed for Earth's gravity in the revision notes?

$$9.8\,m.52$$

What units and representations are specified for weight ($W$), mass ($M$), and gravity ($G$) in Section 1.5?

Weight ($W$) is in Newtons ($N$), mass ($M$) is in $kg$, and gravity ($G$) is $M.52$.

What are the characteristics of a series circuit regarding pathways, total cell calculation ($T_r$), and light output when adding bulbs?

A series circuit has $1\text{ pathway}$, $T_r$ is the sum of all cells, and adding more light bulbs results in less light.

What are the characteristics of a parallel circuit regarding pathways, total cell calculation ($T_r$), and light output when adding bulbs?

A parallel circuit has more than $1\text{ pathway}$, $T_r = 1\text{ cell}$, and adding more bulbs results in the same ammount of light.

What is the definition of resistance provided in the notes?

Opposing the flow of current.

What four factors affect resistance according to the notes?

Length, Thickness, Temperature, and Type of material.
