Physics A Semester Exam Practice

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

How do you calculate the volume of a rectangular prism?

Back

Volume = Length x Width x Height

Front

What is the unit of density in the metric system?

Back

g/cm³ (grams per cubic centimeter)

Front

What is Hooke's Law?

Back

Hooke's Law states that the force exerted by a spring is directly proportional to the amount it is stretched or compressed, within its elastic limit.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What does it mean if a machine is not 100% efficient?

Back

It means that some energy is lost, often as thermal energy, during the operation of the machine.

Front

How do you convert kilometers per hour to meters per second?

Back

Multiply by 5/18.

Front

What is the relationship between speed, distance, and time?

Back

Distance = Speed x Time

Front

What is the significance of negative acceleration?

Back

Negative acceleration indicates that an object is slowing down.

Front

What is the definition of work in physics?

Back

Work is done when a force causes an object to move; calculated as Work = Force x Distance.
