PS Semester 1 Review

Front

What is the independent variable on a graph?

Back

The independent variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable. In this case, it is only temperature (C).

Front

What is buoyant force?

Back

Buoyant force is an upward force exerted by fluids on an object, which allows objects to float or rise in a fluid.

Front

What are arrows that have both magnitude and direction called?

Back

Arrows that have both magnitude and direction are called vectors.

Front

What happens in a circuit if a lightbulb is placed at D and B is closed?

Back

The lightbulb will be on.

Front

What is a pulley?

Back

A pulley is a simple machine that consists of a wheel on an axle or shaft that is designed to support movement and change the direction of force.

Front

What is the definition of a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only and no direction, such as mass or temperature.

Front

What is the definition of a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as force or velocity.

Front

What is the principle of buoyancy?

Back

The principle of buoyancy states that an object submerged in a fluid experiences an upward force equal to the weight of the fluid displaced by the object.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is the law of conservation of energy?

Back

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