Semester 1 Physical Science Final Previous Material

Front

What is the dependent variable in an experiment?

Back

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

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between two or more variables in a scientific investigation.

Front

What are the two components of a vector?

Back

A vector includes direction and magnitude.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, which is directly related to its mass.

Front

How do you calculate net force?

Back

Net force is calculated by summing all the forces acting on an object, taking into account their direction.

Front

What is the formula for speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is a scientific law?

Back

A scientific law is a statement based on repeated experimental observations that describes an aspect of the world.

Front

What is the purpose of a control in an experiment?

Back

A control is used to provide a standard for comparison, ensuring that the results are due to the independent variable.

Front

What is the significance of units in measurements?

Back

Units provide a standard way to quantify measurements, allowing for clear communication and comparison.
