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

According to the principle of conservation of momentum, what is true about the interaction between two isolated objects?

Back

The change in momentum of the 1st object is equal to and opposite to the change in momentum of the 2nd object.

Front

What happens during the collision between two billiard balls according to the conservation of momentum?

Back

The solid ball gains momentum and the white ball loses an equal amount of momentum.

Front

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

Back

m₁v₁initial + m₂v₂initial = m₁v₁final + m₂v₂final

Front

When using the conservation of momentum to solve a problem, what is important to include?

Back

Include all objects involved, their masses, velocities, and direction of motion.

Front

Define momentum in physics.

Back

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

Front

What is an isolated system in the context of momentum?

Back

An isolated system is one where no external forces are acting, allowing momentum to be conserved.

Front

Explain the concept of elastic collision.

Back

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

Front

Explain the concept of inelastic collision.

Back

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

Front

What is the significance of the direction of momentum?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction, which must be considered in calculations.
