Physics Lab and Theory Quiz Review

Vocabulary and conceptual flashcards covering Ohm's Law, circuits, projectile motion, and basic physics laboratory principles based on the quiz transcript.

Ohm’s Law

The law stating that the current flowing through a conductor between two points is directly proportional to the voltage and inversely proportional to the resistance, expressed as $I = V/R$.

Air Resistance

A common source of error in projectile motion experiments when its effects are ignored.

Parallel Circuit

A circuit configuration where voltage is the same across all branches and components are not connected in a single end-to-end pathway.

Leybold-Heraeus Linear Expansion Apparatus

The specific apparatus used for measuring linear expansion in materials.

Series Circuit

A type of circuit configuration where components are connected end-to-end, forming a single pathway for the flow of electric current.

Kirchhoff’s Current Law

A principle based on the conservation of Electric Charge used to analyze the current distribution at a junction.

Uniform Circular Motion Radius/Period Relationship

A physical relationship where increasing the radius causes the period of rotation to increase.

Maximum Range Angle

The angle of $45$ degrees, which achieves the maximum range in projectile motion if the initial height and impact point are equal.

Rotating Platform/ Centripetal Force Accessory

The apparatus used to perform experiments regarding Uniform Circular Motion (UCM).

Series Circuit Resistance

In this configuration, the total resistance is equal to the sum of all individual resistances.

Ampere

The SI unit of electric current.

Ohm

The SI unit of resistance.

Volts

The SI unit of voltage.

Kirchhoff’s Voltage Law

A law used to analyze the voltage distribution in a closed loop circuit.

Horizontal Velocity

The quantity that remains constant in projectile motion along the horizontal direction.

Newton’s Second Law

The law stating that force and acceleration are directly proportional and that a particle acted upon by an unbalanced force will accelerate in the direction of that force.

Angle Indicator

The device used to measure the angle of inclination of the linear air track.

Resultant Force

A single force whose effect is the same as the combined effect of a given set of forces.

Gravitational Acceleration

The value of acceleration for an object in free-fall, equal to $9.8\,m/s^2$.

Experiment #2 Variables

The two variables used for data gathering and computing accelerations: Distance and Time.

Percent Error Formula

$$\frac{\text{Experimental Value} - \text{Theoretical Value}}{\text{Theoretical Value}} \times 100$$
