Physical Science Semester 1 Units (2024)

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) = Force (F) / Mass (m)

Front

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

Back

Newton (N)

Front

What is the work function in the context of the photoelectric effect?

Back

The minimum energy required to remove an electron from a material.

Front

What happens to the potential energy of a ball when it is dropped?

Back

It converts to kinetic energy as it falls.

Front

What type of energy is associated with an object's position?

Back

Potential energy.

Front

What type of energy is associated with an object's motion?

Back

Kinetic energy.

Front

What is the definition of ultraviolet (UV) radiation?

Back

A type of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays.

Front

What is the relationship between temperature and the state of matter?

Back

Temperature affects the kinetic energy of particles, which determines the state of matter (solid, liquid, gas).

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the definition of a wave?

Back

A disturbance that transfers energy through space or matter.
