Newton's 2nd & Momentum Review

Front

In order for an object to have momentum it must be ________

Back

moving

Front

Momentum is a ____________________ quantity

Back

vector

Front

The larger the mass you have the _____ force you need to change its motion.

Back

more

Front

What is the equation for Newton's 2nd law?

Back

F = ma

Front

When two objects collide, the P_before is ____________ the P_after.

Back

equal to

Front

What is momentum?

Back

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

Front

What is the unit of momentum?

Back

Kilogram meter per second (kg·m/s)

Front

How does increasing velocity affect momentum?

Back

Increasing velocity increases momentum, as momentum is directly proportional to velocity.

Front

What does Newton's 2nd law state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

If an object is at rest, what is its momentum?

Back

Zero, because momentum is mass times velocity, and velocity is zero.
