Physics Final Exam

Front

What is a resistor?

Back

A resistor is a device that changes electrical energy into another form of energy, typically thermal energy.

Front

Define wavelength.

Back

Wavelength is the length of one cycle of a wave, measured from crest to crest.

Front

What is an inelastic collision?

Back

An inelastic collision is when objects collide and become stuck together, and kinetic energy is not conserved.

Front

What is an elastic collision?

Back

An elastic collision is when objects collide and bounce off each other, conserving kinetic energy.

Front

What is the photoelectric effect?

Back

The photoelectric effect is the phenomenon where light causes electrons to be emitted from an object.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of its particles.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and combine to form a wave with a larger amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to form a wave with a smaller amplitude.
