Explain why the speed of a sled increase as it moves down a slow-covered hill, even though no one is pushing on the sled .
Depending on the hill and its slope will determine either is will continue to go down the hill at a faster pace . If the hill has a larger slope then it will progress quickly rather than a hill with a smaller slope.

You throw a ball upward and then it falls back down. How does the velocity of the ball changes as it rises and falls?
When the ball is thrown in the air, the velocity could be 5m N . As the ball comes down the velocity could be 10m S. As the ball goes in the air the speed is less than the speed of the ball coming downward.

Have one person from your group come forth and name the first 10 elements of the periodic table of the elements.
How does Newton's Second Law determine the motion of a book as you push it across a desktop?
The second law states that an object acted upon by a net force will accelerate in the direction of this force.

Have 2 members from your group come to the board and List as many formulas. 4 total. ***Helpful Tip ( Speed, Acceleration, Momentum, Newton's Law of Acceleration( due to a net force ) ,
Speed = Distance/Time
Acceleration = final speed - initial speed/time
Momentum = p = mv
Newton's Law of Acceleration( due to a net force ) a = F net / m
OR F net = ma
