Question

How is impulse related to velocity?

Answer 1

Explanation:

1. Impulse: A phrase that is used to explain or measure how a force changes an object's momentum over time. It is often stated in Newton-seconds or kg m/s and denoted by the symbol J.
2. Force and time combine to create the impulse that an item feels. The equation for momentum is as follows:
3. $\overrightarrow{p}=m\overrightarrow{v}$, where mass$=m$, times velocity$=v$, and momentum$=p$. The product of mass and velocity creates a vector known as momentum (which is also a vector).
4. During a collision, an object is subjected to a force for a predetermined period of time, which causes a change in momentum. The mass of the item either accelerates or decelerates as a result of the force applied for the predetermined length of time (or changes direction).
5. The object's change in momentum is equal to the impulse it experiences. The formula is $F•t=\Delta m•v$.
6. The product of an object's mass and velocity determine its change in momentum. The change in momentum is equal to the impulse:

$\begin{array}{l}\mathrm{Impulse}=\mathrm{Force}\times \mathrm{time}\\ \mathrm{Impulse}=\overrightarrow{F}\times \Delta t\end{array}$

An object experiences an impulse as a result of time and force. The product of an object's mass and velocity determine its change in momentum.

Thus, impulse is related to velocity.
