Question 1

Which form of energy is stored in a compressed spring?

Accepted Answer

Elastic potential energy

Answer

A compressed spring stores elastic potential energy due to its deformation from its natural equilibrium position.

Question 2

The law of conservation of energy states that in an isolated system:

Accepted Answer

Total energy remains constant

Answer

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

Question 3

What is the frequency of a wave with a period of 0.02 seconds?

Accepted Answer

50 Hz

Answer

Frequency = 1 ÷ period = 1 ÷ 0.02 = 50 Hz.

Question 4

Which type of wave requires a medium to travel through?

Accepted Answer

Sound waves

Answer

Sound waves are mechanical waves that require a medium (solid, liquid, or gas) to propagate.

Question 5

According to Boyle's Law, if the volume of an ideal gas is halved at constant temperature, its pressure:

Accepted Answer

Doubles

Answer

Boyle's Law states pressure and volume are inversely proportional at constant temperature (PV = constant), so halving volume doubles pressure.
