Day 1 Review Units (1-3)

Front

What is resistance in an electrical circuit?

Back

Resistance is a measure of the opposition to the flow of electric current, measured in ohms (Ω).

Front

How do you calculate resistance using voltage and current?

Back

Resistance (R) can be calculated using Ohm's Law: R = V/I, where V is voltage in volts and I is current in amps.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the formula for calculating speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.

Front

How do you rank speeds of different objects?

Back

To rank speeds, calculate the speed of each object and compare the values; the highest speed is ranked first.

Front

What is wavelength in the context of waves?

Back

Wavelength is the distance between successive crests of a wave, typically measured in meters.

Front

How do you calculate wavelength using wave velocity and frequency?

Back

Wavelength (λ) can be calculated using the formula: λ = Velocity / Frequency.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: a = (Final Velocity - Initial Velocity) / Time.

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed at a specific moment.
