M-Step

The student switches the ball used in Setup 1 with a ball that has a mass of 2 kilograms. Another student states that the potential energy of the 2 kilogram ball would be the same as the potential energy of the 1 kilogram ball since they would be placed at the same height. Which statement best explains whether the student's statement is correct or incorrect?

• The statement is correct because the gravitational force acting on objects with different masses is the same.

• The statement is incorrect because an object with more mass has less potential energy due to increased air resistance.

• The statement is incorrect because more force is needed to lift an object with more mass to the same height as an object with less mass.

• The statement is correct because the potential energy of any object with mass is based on an object's height above the ground and the speed at which it travels.

A student rolls a 3 kilogram ball down the same ramp used in Setup 2. The speed of the ball after 2 seconds was 4 meters per second. The student concludes that the kinetic energy of the 3 kilogram ball is identical to the 1 kilogram ball after it has rolled down the ramp for 2 seconds. Explain whether the student's conclusion is correct or incorrect. Use evidence from the investigation to support your answer.

The table shows the change in the size of willow tree stems in sample areas of the Yellowstone ecosystem between 1995 and 2010. Which conclusion about the number of beaver colonies between 2000 and 2010 is best supported by the data?

• The number of beaver colonies decreased because the amount of available food for the beavers decreased

• The number of beaver colonies increased because the beavers adapted to a change in the food sources available

• The number of beaver colonies increased because the amount of available resources for food and shelter increased

• The number of beaver colonies decreased because the beavers were unable to use the resources for food and to build shelters
