Momentum Flashcard

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that the total momentum of a closed system remains constant if no external forces act on it.

Front

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction.

Front

What factors affect the momentum of an object?

Back

Momentum is affected by the mass of the object and its velocity. Increasing either mass or velocity increases momentum.

Front

What is an elastic collision?

Back

An elastic collision is a type of collision where both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

An inelastic collision is a type of collision where momentum is conserved, but kinetic energy is not.

Front

How do airbags utilize the concept of momentum?

Back

Airbags deploy in a car crash to increase the time over which the momentum of the passenger is reduced, thereby decreasing the force experienced.

Front

What is the formula for calculating momentum?

Back

The formula for calculating momentum is p = mv, where p is momentum, m is mass, and v is velocity.

Front

How does momentum apply in sports?

Back

In sports, momentum is crucial; for example, a baseball player hitting a fast-moving ball transfers momentum from the bat to the ball.

Front

What is the relationship between mass and velocity in momentum?

Back

Momentum is directly proportional to both mass and velocity; if either increases, momentum increases.
