Physical Science Final Exam Review 2023

Front

What is the formula for calculating work?

Back

Work (W) = Force (F) × Distance (d) Where work is measured in Joules (J), force in Newtons (N), and distance in meters (m).

Front

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

Back

The unit of work is the Joule (J).

Front

What is a transverse wave?

Back

A transverse wave is a type of wave in which the motion of the medium is perpendicular to the direction of the wave's travel.

Front

What happens to red litmus paper when placed in a base?

Back

Red litmus paper turns blue when placed in a base.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that is consumed during a chemical reaction.

Front

What is power in the context of physics?

Back

Power is the rate at which work is done, measured in Watts (W).

Front

What is the difference between a mechanical wave and a transverse wave?

Back

A mechanical wave requires a medium to travel through, while a transverse wave is characterized by particle motion that is perpendicular to the direction of wave propagation.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force (F) = Mass (m) × Acceleration (a).

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 kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.
