I have 2 questions that I need help with please.

1.What are the three parts of the law of conservation of mass/matter? Do not need the definition but the 3 laws please.

2. How are velocity, speed, and acceleration related? I know how they are different only.

Thank you

1. i would go on conversation of mass wikipedia. Since they give a lot of detail.

2.Velocity is usually the average of moving from one place to another over a period of time. Ex. running 4 miles in 12 minutes = an average 1/3 miles/hour. Acceleration is the rate of change in a distance over a period of time, so you may have run faster down a hill than up a hill, therefore you would have different acceleration rates during those times or distances. Acceleration is referred to as the "1st derivative" of motion.

Hope this helps :)
