Science ACAP Practice Part 1

A student rolls two bowling balls down the same path. The chart below shows data from the demonstration.

Bowling Ball 1 = Mass 10 kgs, Speed 10 meters per second, 8 knocked down pins.

Bowling Ball 2 = Mass 10 kgs, Speed 5 meters per second, 4 knocked down pins.

Bowling ball ____ has greater speed. Therefore, it has _______ energy because it knocked down ____ pins.

• 1; more, more

• 2, more, more

• 1, less, less

• 2, less, more

Mateo, Katy, and Robb are all competing in a sled race. They raced each other three times. Mateo always started from Height A, Katy always started for Height B, and Robb always started from Height C. In each race, Mateo has the fastest speed at the bottom of the hill and Robb has the slowest speed. Out of the three sledders, who has the most energy?

• Katy
• Robb
• Mateo
• They all have the same amount of energy.

Two identical marbles, Marbles X and Y, are traveling down ramps of the same length. Marble X travels faster down its ramp than Marble Y does. Which marble has more energy as it rolls down the ramp, and why?

• Marble X because more speed equals more energy.
• Marble X because less speed equals more energy.
• Marble Y because more speed equals more energy.
• Marble Y because less speed equals more energy.

A teacher has 4 beakers labeled A through D. Each beaker holds 150 ml of water with 5 g of a different substance. The substances are sugar, flour, salt, and sand. The teacher has built a circuit like the one in the diagram below. After plugging the adaptor into the wall socket, the teach dips the probe on the end of the cable into each beaker. the bulb produces the brightest light when the cable is inserted in the beaker of saltwater.

• Saltwater is a better conductor than the other mixtures.
• Saltwater eats away the metal threads inside a light bulb.
• Salt dissolves more easily in water than sugar, flour, and sand do.
• Salt grains are the right size to conduct electricity well.
