Semester 1 Review Physical Science

Front

What is negative velocity?

Back

Negative velocity indicates that an object is moving in the opposite direction to the reference point, often represented as a decrease in position over time.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined. It determines the object's acceleration.

Front

What is an independent variable in an experiment?

Back

The independent variable is the factor that is deliberately changed or manipulated by the scientist to observe its effect on the dependent variable.

Front

What is distance?

Back

Distance is the total length of the path traveled by an object, regardless of direction.

Front

What is the formula for calculating net force?

Back

Net force (F_net) = Sum of all forces acting on an object.

Front

What is positive velocity?

Back

Positive velocity indicates that an object is moving in the same direction as the reference point, resulting in an increase in position over time.

Front

What is a dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which changes in response to the independent variable.

Front

How do you calculate the total distance traveled?

Back

Total distance traveled is the sum of all segments of the journey, regardless of direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is a control group in an experiment?

Back

A control group is a standard of comparison in an experiment that is not exposed to the independent variable.
