Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

Front

What is the formula for calculating momentum?

Back

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

Front

What is the unit of momentum?

Back

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

Front

How does momentum change when the speed of an object is doubled?

Back

When the speed of an object is doubled, its momentum also doubles.

Front

What happens to the momentum of two skaters who push off each other?

Back

The total momentum before they push off is equal to the total momentum after they push off, according to the law of conservation of momentum.

Front

If two objects collide, what can be said about their momentum before and after the collision?

Back

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

Front

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

Back

Momentum is directly proportional to both mass and speed; increasing either will increase 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 remains constant if no external forces act on it.

Front

How does mass affect the momentum of an object?

Back

An increase in mass will result in an increase in momentum if velocity remains constant.

Front

What is the effect of a larger mass on the speed of an object when two objects push off each other?

Back

The object with the smaller mass will have a greater speed than the object with the larger mass after they push off each other.
