Physics Assessments

Correct:

Diffraction is the phenomenon of waves bending around corners or spreading as they pass through openings.

Correct:

The gravitational force is the fundamental force responsible for the orbital motion of planets around the sun.

Correct:

Momentum is a measure of the quantity of motion an object has, calculated as the product of its mass and velocity.

Correct:

Archimedes' Principle states that the buoyant force on a submerged object is equal to the weight of the fluid it displaces.

Correct:

Energy is defined in physics as the capacity to do work, existing in various forms such as kinetic, potential, thermal, and others.

Correct:

The acceleration due to gravity on Earth is approximately 9.8 meters per second squared.

Correct:

Archimedes' Principle states that an object submerged in a fluid experiences a buoyant force equal to the weight of the fluid it displaces, which explains why ships float on water.

Correct:

Velocity is a vector quantity that refers to the rate at which an object changes its position, defined as the rate of change of displacement and including both magnitude and direction.

Correct:

Kinetic energy, which is the energy of motion, is calculated using the formula KE=\frac{1}{2}mv^2, where m is mass and v is velocity.

Correct:

According to Boyle's Law, if the volume of a gas decreases while its temperature remains constant, the pressure increases.
