CCSS.8.EE.C.7B

The SI unit of impulse.

• Ns

• kgm/s

• kgm/s2

• kg

The impulse-momentum theorem says that the change in momentum of a mass (any object) is equal to the ___

• change in the velocity

• mass times the force

• force time the time it is a applied

• impulse

In using impulse to slow or stop the momentum of a mass, the larger the time used, the

• smaller the force needed

• less change in momentum

• larger the force needed

To stop or slow a mass, the shorter the time a force is applied, the

• smaller the force needed

• larger the force needed

• more no force is needed

• less mass there will be
