Momentum

Front

What is momentum?

Back

Momentum is defined as mass in motion. It is the product of an object's mass and its velocity.

Front

What is the formula for calculating momentum?

Back

The formula for momentum (P) is P = mass (m) × velocity (v).

If a 1000 kg truck is moving at 7 m/s, what is its momentum?

Back

Momentum = 1000 kg × 7 m/s = 7000 kg*m/s.

Front

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum, assuming velocity remains constant.

Front

How does velocity affect momentum?

Back

The greater the velocity of an object, the greater its momentum, assuming mass remains constant.

Front

What happens to momentum in a closed system during a collision?

Back

In a closed system, the total momentum before the collision is equal to the total momentum after the collision.

Front

What is the unit of momentum?

Back

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

Front

What is the relationship between momentum and velocity?

Back

Momentum is directly proportional to velocity; if velocity increases, momentum increases.

Front

What is an example of a high momentum object?

Back

A large truck moving at a high speed has high momentum due to its large mass and velocity.

Front

What is an example of a low momentum object?

Back

A small ball rolling slowly has low momentum due to its small mass and low velocity.
