IPC Fall Semester Review

Front

What is the formula for Gravitational Potential Energy?

Back

PE = m*g*h

Front

What is the formula for Kinetic Energy?

Back

KE = 1/2m*v²

Front

How do we express the total amount of energy a moving object has?

Back

KE + PE

Front

What is the definition of frequency in relation to waves?

Back

Frequency is the number of complete cycles of a wave that occur in one second, measured in Hertz (Hz).

Front

What is the definition of period in relation to waves?

Back

Period is the time it takes for one complete cycle of a wave to pass a given point, measured in seconds.

Front

If a wave has a frequency of 3 Hz, what is its period?

Back

Period = 1 / Frequency = 1 / 3 Hz = 0.333 seconds.

Front

What is the relationship between frequency and period?

Back

Frequency is the inverse of period; as frequency increases, period decreases.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in motion.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy is the Joule (J).
