Momentum Conceptual Questions

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 in a closed system with no external forces, the total momentum before an event (like a collision or explosion) is equal to the total momentum after the event.

Front

What happens to momentum in an elastic collision?

Back

In an 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; some kinetic energy is transformed into other forms of energy.

Front

How does the mass of an object affect its momentum?

Back

The momentum of an object increases with an increase in mass, assuming velocity remains constant, as momentum is directly proportional to mass.

Front

If two objects collide and stick together, what type of collision is it?

Back

It is an inelastic collision.

Front

What is the formula for calculating momentum?

Back

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

Front

If an object is at rest, what is its momentum?

Back

If an object is at rest, its momentum is zero because velocity is zero.

Front

What is the effect of throwing an object in space on the thrower?

Back

When an object is thrown in space, the thrower will move in the opposite direction due to the conservation of momentum.

Front

What is the total momentum of a system of objects before and after an explosion?

Back

The total momentum of a system of objects is conserved; it remains the same before and after the explosion.
