Ch12 Test - Short

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, indicating how much motion an object has.

Front

How do you calculate momentum?

Back

Momentum (p) = mass (m) × velocity (v).

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What are the two types of forces?

Back

Contact forces and non-contact forces.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for acceleration?

Back

Acceleration (a) = (final velocity - initial velocity) / time.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through air.

Front

What are the four universal forces?

Back

Gravitational, electromagnetic, strong nuclear, and weak nuclear forces.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses.
