Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the equation p = m x v.

Front

What is the unit of momentum?

Back

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

Front

What is an elastic collision?

Back

An elastic collision is a type of collision where the total kinetic energy and total momentum are conserved, and the objects bounce apart.

Front

What is an inelastic collision?

Back

An inelastic collision is a type of collision where the total momentum is conserved, but the total kinetic energy is not conserved, and the objects may stick together.

Front

What does the conservation of momentum state?

Back

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

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = m x v, where m is mass and v is velocity.

Front

What factors affect momentum?

Back

Momentum depends on two factors: mass and velocity of the object.

Front

What is the relationship between mass and velocity in momentum?

Back

Momentum increases with an increase in either mass or velocity; if either is greater, the momentum will be greater.

Front

What happens to momentum in a closed system during a collision?

Back

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

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved; in inelastic collisions, only momentum is conserved.
