Conservation of Momentum 4.2

Front

What is the principle called that states the total momentum of a system remains constant if no external forces act on it?

Back

Law of conservation of momentum

Front

What is the formula that represents the conservation of momentum for two colliding balls?

Back

m₁v₁initial + m₂v₂initial = m₁v₁final + m₂v₂final

Front

What happens to objects in an inelastic collision?

Back

They deform and lose kinetic energy.

Front

According to the equation provided, which of the following represents the conservation of momentum for two colliding objects that move together after collision?

Back

m₁v₁i + m₂v₂i = (m₁ + m₂)vf

Front

What happens to the total kinetic energy of two objects in an elastic collision?

Back

It remains the same.

Front

Define momentum in physics.

Back

Momentum is the product of an object's mass and its velocity (p = mv).

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.

Front

What is the formula for calculating momentum?

Back

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

Front

What is the significance of the conservation of momentum in closed systems?

Back

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