When a force acts on an object, the object's momentum changes, according to the symbol equation: F × t = m × v - m × u . Complete this word equation: I m p u l s e o f f o r c e =

Forces acting a very short time are called impulse forces. The impulse equals the change in momentum. So, the word equation will be; I m p u l s e f o r c e = C h a n g e i n m o m e n t u e m

When a force acts on an object, the object's momentum changes, according to the symbol equation: F × t = m × v - m × u . Explain what each of the five symbols in the symbol equation represents.

The given equation represents the impulse. The impulse equals the change in momentum. The symbols in the given equation represents: F × t = m × v - m × u Where, F is force applied on the object, t is the short time period, m is the mass of the object, v is the final velocity of object, u is the initial velocity of an object.
