Section 1

(21 cards)

Velocity

Front

The speed of the object and the direction of its motion.

Back

40,000 kg m/s

Front

A car has a momentum of 20,000 kg • m/s. What would the car's momentum be if its velocity doubles?

Back

9 kg

Front

A bicycle has a momentum of 36 kg • m/s and a velocity of 4 m/s. What is the mass of the bicycle?

Back

Unit for velocity

Front

Velocity is measured in meters per second (m/s)

Back

Trough

Front

the opposite of a crest, so the minimum or lowest point in a cycle.

Back

Medium

Front

something waves travel through

Back

Amplitude

Front

The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.

Back

How does wave speed change?

Front

Only by changing the medium! NOT wavelength or frequency.

Back

6.0 kg m/s

Front

What is the momentum of a 5 kg object that has a velocity of 1.2 m/s?

Back

Y, W, X, Z

Front

The chart shows masses and velocities of four objects. Which lists the objects in order, from least to greatest momentum?

Back

Momentum formula

Front

mass x velocity

Back

Crest

Front

a point on the wave where the displacement of the medium is at a maximum.

Back

Frequency

Front

the number of waves per second

Back

Z

Front

The chart lists the masses and velocities of four objects. Which object requires the greatest change in momentum in order to stop its motion?

Back

Wavelength

Front

the distance between 2 crests or 2 troughs of a wave, especially points in a sound wave or electromagnetic wave.

Back

Interference (CONSTRUCTIVE, DESTRUCTIVE)

Front

Destructive- pulses of a wave completely cancel each other; it is as if there were no disturbance at all at the instant the two pulses overlap. (opposite of equilibrium) Constructive- when the resultant wave is larger than the individual displacements. (same side of equilibrium)

Back

Period

Front

the time for a particle on a medium to make one complete vibrational cycle. Period Equation= 1 / f (frequency).

Back

Unit for mass

Front

Mass is measured in kilograms (kg)

Back

Impulse formula

Front

Force x time.

Back

Friction

Front

Force that opposes motion between two surfaces.

Back

Wave speed formula

Front

wavelength x frequency
