DOL_Momentum and Conservation of Momentum

Front

What is momentum?

Back

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 does mass affect momentum?

Back

An object's momentum increases with its mass if its velocity remains constant. A heavier object moving at the same speed as a lighter object will have greater momentum.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before and after a collision remains constant, provided no external forces act on it.

Front

What happens to momentum in a collision?

Back

In a collision, momentum is transferred between the colliding objects. The total momentum of the system is conserved.

Front

Calculate the momentum of a 2 kg object moving at 3 m/s.

Back

Momentum = mass × velocity = 2 kg × 3 m/s = 6 kg*m/s.

Front

What is the difference between elastic and inelastic collisions?

Back

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

Front

What is the formula for calculating momentum?

Back

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

Front

If a car and a truck collide, which has more momentum?

Back

The object with greater mass or greater velocity will have more momentum. If the truck is heavier or moving faster, it will have more momentum.

Front

What is the unit of momentum?

Back

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

Front

How does velocity affect momentum?

Back

An increase in velocity will increase the momentum of an object, assuming mass remains constant.
