During intercourse, the penis ejaculates sperm, produced in the testes, into the vagina. Some of the sperm makes their way to the uterus where, if they encounter an egg to fertilize, unite with the ovum to form a fertilized egg or zygote. The zygote then may implant in the uterus and eventually develop into a fetus.
Momentum is a measure of how difficult it is for a moving object to stop. Which of the following is the formula for momentum?
none of these |
|
\(\vec{p} = { \vec{v} \over m}\) |
|
\(\vec{p} = m\vec{v}\) |
|
\(\vec{p} = {m \over \vec{v}}\) |
Momentum is a measure of how difficult it is for a moving object to stop and is calculated by multiplying the object's mass by its velocity: \(\vec{p} = m\vec{v}\). Like velocity, momentum is a vector quantity as it expresses force applied in a specific direction.
