phy sci midterm physics

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, such as a rock at the edge of a cliff.

Front

What happens to resistance when the diameter of a wire decreases?

Back

Resistance increases, causing fewer electrons to flow through the circuit.

Front

What is a step-down transformer?

Back

A device that decreases voltage by decreasing the number of turns in the secondary coil.

Front

What is a parallel circuit?

Back

A circuit where two or more paths are available for current to flow, allowing multiple devices to operate independently.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is the formula for calculating potential energy?

Back

Potential Energy (PE) = mass (m) × gravity (g) × height (h).

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, all components are connected in a single path, while in a parallel circuit, components are connected across multiple paths.

Front

What is Ohm's Law?

Back

Ohm's Law states that voltage (V) = current (I) × resistance (R).

Front

What is the role of a resistor in a circuit?

Back

A resistor limits the flow of electric current in a circuit.
