Front

What is the condition for a system to undergo acceleration?

Back

A system undergoes acceleration only when acted on by a net force (total force > 0N).

Front

What axis label does column A represent by default in a Google Sheets graph?

Back

Column A represents the X-axis label by default.

Front

How do you calculate the displacement of an object that moves south 5 miles and then west 2 miles?

Back

Use the Pythagorean Theorem: Displacement = √(5² + 2²) = 5.39 miles SW.

Front

What is the purpose of a conclusion in an experiment?

Back

A conclusion uses data to answer a question, including the independent variable (IV) and dependent variable (DV) in statement form after the investigation.

Front

What must you do before conducting an experiment?

Back

You must form a hypothesis before conducting an experiment.

Front

Define net force.

Back

Net force is the total force acting on an object, calculated by vector addition of all individual forces.

Front

What is a hypothesis?

Back

A hypothesis is a testable statement predicting the relationship between variables in an experiment.

Front

What is the difference between independent and dependent variables?

Back

The independent variable is manipulated by the experimenter, while the dependent variable is measured in response.

Front

What is the Pythagorean Theorem?

Back

The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides (a² + b² = c²).

Front

What is data analysis?

Back

Data analysis involves interpreting and making sense of collected data to draw conclusions.
