CBA 3 Review

Front

Where is the potential energy the greatest?

Back

Potential energy is greatest at the highest point in a system, where an object has the most stored energy due to its position.

Front

What is the magnitude (size) and direction of the net force?

Back

Net force is the overall force acting on an object, calculated by combining all individual forces, taking into account their directions.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the medium moves in a direction parallel to the direction of the wave's travel, such as sound waves.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

What are compressions in a longitudinal wave?

Back

Compressions are the regions in a longitudinal wave where the particles of the medium are closest together.

Front

What are rarefactions in a longitudinal wave?

Back

Rarefactions are the regions in a longitudinal wave where the particles of the medium are spread apart.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, often related to height in a gravitational field.

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.
