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

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

Front

How does velocity affect momentum?

Back

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

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 two objects have the same velocity, which one has more momentum?

Back

The object with the greater mass will have more momentum.

Front

What happens to momentum in a collision?

Back

In a closed system, the total momentum before the collision is equal to the total momentum after the collision (law of conservation of momentum).

Front

What is an example of an object with high momentum?

Back

A car driving on the freeway has high momentum due to its large mass and high velocity.

Front

What is an example of an object with low momentum?

Back

A butterfly in flight has low momentum compared to a car, even if both are moving.

Front

How do you calculate the momentum of an object with a mass of 20 kg and a velocity of 4 m/s?

Back

Momentum = mass x velocity = 20 kg x 4 m/s = 80 kgm/s.

Front

What is the relationship between momentum and speed?

Back

Momentum increases with speed; if the mass is constant, doubling the speed will double the momentum.
