Linear Momentum

What is Linear Momentum?

Back

Linear 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

How is momentum calculated?

Back

Momentum (p) is calculated using the formula: p = mv, where m is the mass of the object and v is its 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) is equal to the total momentum after the event.

Front

What happens to momentum in a collision?

Back

In a collision, the total momentum of the system (the colliding objects) is conserved, provided no external forces act on it.

Front

What is an elastic collision?

Back

An elastic collision is a type of collision where both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

An inelastic collision is a type of collision where momentum is conserved, but kinetic energy is not conserved.

Front

What is the formula for calculating the change in momentum?

Back

The change in momentum (Δp) is calculated as Δp = p_final - p_initial.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as Impulse = Force × Time.

Front

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum for a given velocity, as momentum is directly proportional to mass.

Front

How does velocity affect momentum?

Back

The greater the velocity of an object, the greater its momentum, as momentum is directly proportional to velocity.
