I'm sorry, but I cannot see the columns or the options to drag and drop. Could you please provide more information or specify the options and columns that need to be matched?
a ball rolling across the floor until bradley kicks it
ur carf breaks down your friend helps u push it ; it begins to move and speed up
when riding the bumper cars at the fair you bump into ur friend and your car bounces back
Based on the given information, the items can be matched with the following Newton's laws:
Newton's 1st Law: a ball rolling across the floor until Bradley kicks it
Newton's 2nd Law: your car breaks down, your friend helps you push it; it begins to move and speed up
Newton's 3rd Law: when riding the bumper cars at the fair, you bump into your friend and your car bounces back

What best explains why the Moon's surface gravity is only one-sixth of Earth's surface gravity?
(1 point)
Responses
Gravity is the result of an object's mass and size; the Earth is much larger than the moon.
Gravity is the result of an object's mass and size; the Earth is much larger than the moon.
The moon orbits Earth faster than Earth orbits the Sun, giving the moon less gravity.
The moon orbits Earth faster than Earth orbits the Sun, giving the moon less gravity.
Earth is closer to the Sun, so it has much more gravity.
Earth is closer to the Sun, so it has much more gravity.
Gravity is controlled by the tides, which are much closer to Earth than the moon.
The best explanation for why the Moon's surface gravity is only one-sixth of Earth's surface gravity is:
Gravity is the result of an object's mass and size; the Earth is much larger than the moon.
