What is the unit for momentum?

Back

kg m/sec

Front

When the speed of an object is doubled, its momentum:

Back

doubles

Front

In any collision (crash) the ______ is ALWAYS constant

Back

Total Momentum

Front

The momentum of an object depends upon the object's ___________&_____________.

Back

mass and velocity

Front

The equation to calculate momentum is:

Back

p=mv

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before and after a collision remains constant.

Front

How does mass affect momentum?

Back

Greater mass results in greater momentum if velocity is constant.

Front

How does velocity affect momentum?

Back

Greater velocity results in greater momentum if mass is constant.

Front

What happens to momentum in an elastic collision?

Back

Total momentum and total kinetic energy are conserved.
