1. What does 'Newton's First Law of Motion' state?

AA body remains at rest or in uniform motion unless acted upon by an external force
BForce equals mass times acceleration (F=ma)
CA body immersed in a fluid experiences an upward buoyant force equal to the weight of fluid displaced
DEnergy can neither be created nor destroyed, only transformed

Show answer

Answer: A

'Newton's First Law of Motion' states that: A body remains at rest or in uniform motion unless acted upon by an external force.

2. What does 'Newton's Second Law of Motion' state?

APressure applied to a confined fluid is transmitted equally in all directions
BAt constant temperature, pressure of a gas is inversely proportional to its volume
CForce equals mass times acceleration (F=ma)
DAn increase in fluid speed occurs with a decrease in pressure

Show answer

Answer: C

'Newton's Second Law of Motion' states that: Force equals mass times acceleration (F=ma).

3. What does 'Archimedes' Principle' state?

AForce equals mass times acceleration (F=ma)
BA body immersed in a fluid experiences an upward buoyant force equal to the weight of fluid displaced
CAt constant pressure, volume of a gas is directly proportional to its temperature
DCurrent through a conductor is directly proportional to the voltage across it

Show answer

Answer: B

'Archimedes' Principle' states that: A body immersed in a fluid experiences an upward buoyant force equal to the weight of fluid displaced.

4. What does 'Pascal's Law' state?

AEnergy can neither be created nor destroyed, only transformed
BAt constant pressure, volume of a gas is directly proportional to its temperature
CPressure applied to a confined fluid is transmitted equally in all directions
DAt constant temperature, pressure of a gas is inversely proportional to its volume

Show answer

Answer: C

'Pascal's Law' states that: Pressure applied to a confined fluid is transmitted equally in all directions.

5. What does 'Ohm's Law' state?

AA body remains at rest or in uniform motion unless acted upon by an external force
BAn increase in fluid speed occurs with a decrease in pressure
CCurrent through a conductor is directly proportional to the voltage across it
DFor every action, there is an equal and opposite reaction

Show answer

Answer: C

'Ohm's Law' states that: Current through a conductor is directly proportional to the voltage across it.
