Momentum

Front

What is momentum?

Back

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

Front

What is the unit of momentum?

Back

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

Front

Is momentum a scalar or vector quantity?

Back

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

Front

What happens to momentum in a closed system?

Back

In a closed system, the total momentum before and after an event (like a collision) remains constant.

Front

What is the principle of conservation of momentum?

Back

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

Front

How does doubling the speed of an object affect its momentum?

Back

If the speed of an object is doubled, its momentum also doubles.

Front

What is the relationship between mass and momentum?

Back

Momentum is directly proportional to mass; increasing the mass of an object increases its momentum.

Front

What is a collision in terms of momentum?

Back

A collision is an event where two or more bodies exert forces on each other for a relatively short time, affecting their momentum.

Front

What is an elastic collision?

Back

An elastic collision is one in which both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

An inelastic collision is one in which momentum is conserved, but kinetic energy is not.
