Momentum Test Review

mass

Momentum is the product of an object's ________ and velocity

impulse

The quantity Ft is called _________

kg*m/s

The unit of momentum in SI is ________

impulse

The change of momentum for an object is equal to and caused by the __________ given to the object

loss

Any gain of momentum by an object occurs only by the _______ of a corresponding amount of momentum by another object

m(delta)v

Complete the equation Ft = __________

In a system consisting of objects upon which no external force is acting, the momentum of the system is __________

conserved

zero

Two objects of equal mass approach each other head on with the same speed. The total momentum of the system before the collision takes place equals _________

internal

A(n) ___________ force cannot change the momentum of a system

direction

Because both ______ and magnitude must be taken into account when adding momenta, momentum is a vector quantity

negative

If the momentum of a cannon is considered positive after it fires a shell, the momentum of the shell is considered ________

accelerations

Which quantities do not always occur in equal and opposite pairs when an interaction takes place within a system?

isolated system

No external forces act on the system (or the net = zero)

closed system

No objects enter or leave (no gain/loss of mass)

momentum

When mass is multiplied by velocity, the answer is a measure of ______

Law of Conservation Of Momentum

The ________ states that the momentum of any closed, isolated system does not change

Impulse-Momentum Theorem

The ______ states that the impulse on an object is equal to the change in the object's momentum

Elastic collision

A collision where both momentum and kinetic energy are conserved

Inelastic Collision

A collision where momentum is conserved, but kinetic energy is not, some energy is lost to other forms like heat or sound

Momentum Conservation

Momentum is conserved in both elastic and inelastic collisions
