The speed of an object in a particular direction.
Momentum is always conserved, so provided no pieces come off:initial momentum = final momentum (where momentum is mass*velocity)MU=MV+mv is the equation to be used, if m is very small, then V is roughly equal to U, that is that if the stationary object is very light compared to the moving one, the moving one doesn't change it's veocity very much and the smaller one moves at a similar speed. I m is bigger (like a wall), the moving mass can stop, or even reverse its motion.if energy is conserved, speed of separation = speed of approach (ie. U=v-V)I hope this was helpful to youI don't know if this is right! :o
An object that decreases its speed also decreases the magnitude of its velocity and decreases the magnitude of its momentum. Momentum is mass time velocity. Less velocity, less momentum. Technically, velocity is a vector and therefor momentum is a vector. One can speak of smaller or larger magnitudes of a vector, but not smaller and larger vectors because vectors have magnitude and direction. Speed is the magnitude of velocity.
Under free fall, the only force acting upon an object is the force of gravity. But realistically, there is also the force of friction from the air (Air Resistance) that opposes the force of gravity.
The formula for velocity is velocity = distance / time. It represents the rate at which an object changes its position.
The oil has less veocity therfore your engine must warm up the oil and the eninge at the same time. Also you probly have the heater on and that draws from your alternator and makes it work with puts strian on your motor
