Physical Science Fall Exam 2024

Front

What is conduction in heat transfer?

Back

Conduction is the process of heat transfer through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is the formula to calculate force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is the direction of heat flow?

Back

Heat always flows from higher temperature to lower temperature.

Front

What does a flat line on a velocity vs. time graph indicate?

Back

A flat line indicates zero acceleration.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot soup.

Front

What is the significance of the slope in a velocity vs. time graph?

Back

The slope of a velocity vs. time graph represents acceleration.

Front

What is a hypothesis in the scientific method?

Back

A hypothesis is a testable prediction about the relationship between variables.
