Momentum, Impulse, and Newton's 3rd Law

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 formula for calculating impulse?

Back

Impulse is calculated using the formula Impulse = Force × Time, which represents the change in momentum of an object.

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum for a given velocity, as momentum is directly proportional to mass.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg m/s).

Front

In a perfectly elastic collision, what is conserved?

Back

In a perfectly elastic collision, both momentum and kinetic energy are conserved.

Front

What happens to momentum in an inelastic collision?

Back

In an inelastic collision, momentum is conserved, but kinetic energy is not conserved.

Front

If a 2 kg object is moving at 3 m/s, what is its momentum?

Back

The momentum is 6 kg m/s (calculated as p = mv = 2 kg × 3 m/s).

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object, expressed as Impulse = Δp.

Front

What is the effect of doubling the velocity of an object on its momentum?

Back

Doubling the velocity of an object doubles its momentum, since momentum is directly proportional to velocity.
