Physics Final Review

Front

What is wave-particle duality?

Back

Wave-particle duality is the concept in quantum mechanics that every particle or quantum entity can be described as either a particle or a wave. For example, photons can exhibit properties of both waves and particles.

Front

What is an Electric Generator?

Back

An Electric Generator is a device that converts mechanical energy into electrical energy, typically by rotating a coil of wire within a magnetic field.

What is the purpose of gamma particles in radiation therapy?

Back

Gamma particles are used in radiation therapy to help stop the growth of cancer cells by damaging their DNA.

Front

What is an Emission Spectrum?

Back

An Emission Spectrum is a spectrum of the electromagnetic radiation emitted by a source, which can be used to identify the elements present in a sample.

Front

What is a Superconductor?

Back

A Superconductor is a material that can conduct electricity without any resistance when cooled below a certain temperature.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law of Motion states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula for calculating kinetic energy?

Back

The formula for calculating kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the law of universal gravitation?

Back

The law of universal gravitation states that every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
