Forces Density Electricity Review

Front

What is the direction of electron flow in relation to current?

Back

Electrons flow in the opposite direction to the current.

Front

Why is it harder to stop a four-person rowing team than a three-person rowing team?

Back

The four-person team has more mass and more kinetic energy.

Front

What happens to kinetic energy as the speed of an object increases?

Back

The faster an object moves, the more kinetic energy it has.

Front

What type of circuit does not work if one bulb goes out?

Back

A series circuit.

Front

What is the relationship between mass and kinetic energy?

Back

More mass results in more kinetic energy if speed is constant.

Front

What does a steeper graph indicate in terms of acceleration?

Back

A steeper graph represents greater acceleration.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, all components are connected in a single path; in a parallel circuit, components are connected across common points.

Front

What is the unit of electric current?

Back

Ampere (A).

Front

What is density?

Back

Density is mass per unit volume, typically expressed in grams per cubic centimeter (g/cm³).
