Question

Sheila and Kevin are helping their science teacher design a lab exercise about gravity in the universe. The simple set-up requires the use of two softballs. Ball t has nothing attached to it. Ball 2 has a long string connected to it. The first step of the activity is to throw Ball 1 in a straight line down the hallway to model a planet that is not affected by the Sun's gravity. What should be done in Step 2 to model the Sun's effect on a planet? A The ball is thrown around the body while holding on to the string. B The ball is thrown around the body with the string trailing behind. C The ball is thrown in a straight line while holding the string. D The ball is thrown in a straight line with the string trailing behind.

Answer 1

To model the Sun's effect on a planet, the ball should be thrown in a straight line with the string trailing behind.

Step-by-step explanation:

In order to model the Sun's effect on a planet, the ball should be thrown in a straight line with the string trailing behind. This is option D.

By throwing the ball in a straight line with the string trailing behind, we are representing the gravitational pull of the Sun on the planet. The string acts as the force of gravity that keeps the planet in its orbit around the Sun.
