The units for Impulse are

• N/s
• N.s
• N
• m/s

The impulse-momentum theorem states that

• the impulse on an object is equal to the change in momentum it causes 
• the force on a moving object is equal to the magnitude of the impulse.
• the impulse on an object is greater than the change in momentum it causes 
• the impulse on an object is less than the change in momentum it causes
