Momentum is a vector, it is mass times velocity. To say that momentum slows is the same as saying that velocity (speed) drops - it is making something simple sound complicated.

Why did the neighbor say you had great acceleration as you slowed down and swerved to avoid hitting a rock?
Because you had good speed and good direction in velocity.
What does the law of conservation of momentum say about the total amount of momentum after a collision?
the total momentum after a collision must be equal the total momentum before the collision.
Is it true that an object never loses its momentum?
Momentum is related to velocity and mass. When an object's velocity is zero relative to its surroundings, it has no momentum. Therefore it is untrue to say that an object never looses its momentum.
How much momentum does and object have when it stops?
The Same! The statement above is true depending on what u mean. Think of it as a person running. While the person is running they have momentum ( momentum is mass times velocity). Now say they for some reason have to suddenly stop all at once, at the exact moment they stop the momentum is the same, this is why their body would jerk forward. However after that, when they were no longer moving, they would no longer have momentum, mathematically speaking that person's mass times their velocity of zero is then zero.
What is an example of transformation between kinetic energy and thermal energy?
Any time an object is slowed down by friction, most of the kinetic energy is converted to thermal energy.Any time an object is slowed down by friction, most of the kinetic energy is converted to thermal energy.Any time an object is slowed down by friction, most of the kinetic energy is converted to thermal energy.Any time an object is slowed down by friction, most of the kinetic energy is converted to thermal energy.

When the momentum within a system is the same before and after an event you say that what?
You say that momentum is conserved. This is always the case, if the system has no interaction with anything outside the system.

Why is it incorrect to say that impulse equals momentum?
Impulse is the change in momentum. Therefore Impulse is only equal to momentum if the initial momentum was equal to zero. Its the same phenomenon as position and displacement. Impulse= final momentum-initial momentum= mv - mv_0= Force * Time Where m is the mass and v is the velocity.
If a truck has a momentum of 25000 kg ms and a car has a momentum of 5000 kg ms what is the total momentum of the two truck?
i would have to say 30000 kg ms but i may be wrong
What what do theorists mean when the say black holes have no hair?
They mean that black holes can only exhibit mass and momentum and nothing else (i.e. they cannot exhibit any other characters, or "hair").
How would you say moment of immortality in Latin?
Momentum Immortalitas
What if your friend says that the law of conservation of momentum violated when a ball rolls down a hill and gain momentum what do you say?
it could be said that since potential energy (mgh) is lost at the exact rate kinetic energy (ke) is gained, that energy is translated into another form since force applied (gravity) over time then impulse applied and increase of momentum

What does calm and unruffled mean?
calm down mean when like your mad so people usually say "calm down "
