Conservation of Momentum

Front

What is momentum?

Back

Momentum is defined as mass in motion.

Front

How does momentum relate to Newton's laws?

Back

Momentum is inertia in motion.

Front

What are the units of momentum?

Back

The units of momentum are kg m/s.

Front

What does the Law of Conservation of Momentum state?

Back

The total momentum before a collision is equal to the total momentum after a collision.

Front

When two objects collide, how does their momentum before the collision compare to their momentum after the collision?

Back

The momentum before the collision is equal to the momentum after the collision.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v).

Front

What is an example of a situation where momentum is conserved?

Back

In a closed system, such as two ice skaters pushing off each other, the total momentum before and after the push remains the same.

Front

What is the difference between elastic and inelastic collisions in terms of momentum?

Back

In elastic collisions, both momentum and kinetic energy are conserved; in inelastic collisions, momentum is conserved but kinetic energy is not.

Front

What happens to momentum in an explosion?

Back

In an explosion, the total momentum before the explosion is equal to the total momentum after the explosion, as momentum is conserved.

Front

How does mass affect momentum?

Back

Momentum increases with greater mass if velocity remains constant.
