If the velocity of an object doubles, its momentum:

• doubles.

• halves.

• remains the same.

• quadruples.

The units for Impulse are

• N/s

• N*s

• N

• m/s

If the mass of an object remains constant, when I increase the speed with a direction called the ​ (a)   by a factor of (x2), then the ​ (b)   increase by a factor of ​ (c)  

• momentum

• two

• velocity
