In any collision (crash) the ______ is ALWAYS constant

Back

Total Momentum

Front

What is the formula for momentum?

Back

Momentum = mass × velocity

Front

What is the relationship between force and momentum?

Back

Force is the rate of change of momentum.

Front

What is the principle of conservation of momentum?

Back

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

Front

How does increasing mass affect momentum if velocity is constant?

Back

Increasing mass increases momentum.

Front

How does increasing velocity affect momentum if mass is constant?

Back

Increasing velocity increases momentum.
