PhySci Midterm Review

Front

What type of data is collected if participants rate their satisfaction on a scale from 1 to 5?

Back

Quantitative data is numerical and can be measured, such as ratings on a scale.

Front

Which of the following is a good conductor of electricity?

Back

Copper is a metal that allows electricity to flow through it easily.

Front

How much work is done by a force of 30 N acting over a distance of 5 meters?

Back

Work is calculated using the formula: Work = Force x Distance. Therefore, Work = 30 N x 5 m = 150 J.

Front

The relationship between current, voltage, and resistance is described by _______________________.

Back

Ohm’s law states that Voltage = Current x Resistance.

Front

Which of the following best defines speed?

Back

Speed is defined as the total distance traveled divided by the total time taken.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy = 1/2 mv², where m is mass and v is velocity.

Front

What is the unit of electrical resistance?

Back

The unit of electrical resistance is the Ohm (Ω).

Front

What is the principle of conservation of energy?

Back

The principle states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational Potential Energy = mgh, where m is mass, g is acceleration due to gravity, and h is height.
