Now place your skateboarder at the 6 meters mark and let the investigation play out. You can play it at Normal Speed. What happened and why? Type Answer HERE:

If we could increase the height of the ramp to start at 12 meters. How would this affect the overall Kinetic & Potential Energy of the investigation? Explain why.

Increase the Mass of the skater to Large by using the slider in the gray box for mass. How does the mass of the skater change the total amount of energy?

. Based on the information given in the table, the skateboarder has the greatest potential energy at point A. Explain why

2. At which point in the image, would the skateboarder have the greatest Kinetic Energy & Why?

How does the type of material used as an insulator affect heat transfer? Use evidence to support you from the text given.

How does the movement of particles within a substance contribute to heat transfer?

If you were to build a home that effectively kept the cool air in during the summers and the hot air in during the winters, what materials would you choose and why?

The student says that a ball dropped from a height of 3.0 meters would have less than 96 joules of kinetic energy when it hits the ground. Is she correct and why? Type Answer HERE:

Byrd has a mug of coffee at a temperature of 93°C. He sets the mug on a counter in a room with an air temperature of 25°C. What is most likely to happen to the temperature of the coffee? Type Answer HERE: a. The hot coffee will transfer thermal energy int...

9. A student drops a ball from three different heights, as shown. For each drop, she calculates what the kinetic energy of the ball would be when it hits the ground. The table shows her data. The student says that a ball dropped from a height of 3.0 meter...

7x+3=7x+3 is this a infinte solution?

5x+5=5x+4 is this a one soultion?

5x + 5 = 5x + 4 infinte,one soultion,no solutions

What do you notice about these equations? 7x + 3 = 7x + 3 4x + 22 = 8x + 10

Consider the two equations you circled, which form a system with infinite solutions. Solve the equations.

Consider the two equations you put a square around, which form a system with no solution. Solve the equations. 2x+3=2x+7 5x+5=5x+4

What do you notice about these equations? 2x + 3 = 2x + 7 2x + 3 = 2x + 7

What do you notice about these equations? 2x + 3 = 2x + 7 5x + 5 = 5x + 4

What does it mean to have no solutions?

Consider the two equations that you underlined, which form a system with one solution. Solve the equations. 3x+18=5x+8 3(4x8)=4(3x+)

3(4x + 8) = 4(3x +6)
