Newtons Laws & Momentum

Front

What is the principle of conservation of momentum in a collision?

Back

In any collision, the total momentum of the system before the collision is equal to the total momentum after the collision, provided no external forces act on it.

Front

What two factors determine the momentum of an object?

Back

The momentum of an object depends on its mass and velocity.

Front

How do you calculate the momentum of an object?

Back

Momentum (p) is calculated using the formula p = mass (m) × velocity (v).

Front

What is Newton's 1st Law of Motion?

Back

An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an outside force.

Front

What is the unit of momentum?

Back

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

Front

What happens to momentum in an elastic collision?

Back

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

Front

What happens to momentum in an inelastic collision?

Back

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

Front

What is the relationship between mass and velocity in determining momentum?

Back

Momentum is directly proportional to both mass and velocity; increasing either will increase momentum.

Front

What is the formula for calculating momentum?

Back

The formula for momentum is p = m × v, where p is momentum, m is mass, and v is velocity.

Front

What does it mean for momentum to be conserved?

Back

Momentum is conserved when the total momentum of a closed system remains constant over time, regardless of the interactions within the system.
