Question

8. Which pulls harder gravitationally, the E arth on the Moon, or the Moon on the Earth? Which accelerates more? (a) The Earth on the Moon; the Earth. (b) The Earth on the Moon; the Moon. (c) The Moon on the Earth; the Earth. (d) The Moon on the Earth; the Moon. (e) Both the same ; the Earth. (f) Both the same ; the Moon.

Answer 1

(e) Both the same; the Earth.

Answer 2

## Step 1According to Newton's third law of motion, every action has an equal and opposite reaction. This means that the force exerted by the Earth on the Moon is equal to the force exerted by the Moon on the Earth.## Step 2The acceleration experienced by each body due to the gravitational pull of the other is inversely proportional to their masses. This means that the Earth experiences less acceleration than the Moon due to its larger mass.## Step 3However, the force is the same because force is the product of mass and acceleration. Therefore, the Earth pulls on the Moon with the same force that the Moon pulls on the Earth.## Step 4The acceleration experienced by each body due to the gravitational pull of the other is inversely proportional to their masses. This means that the Earth experiences less acceleration than the Moon due to its larger mass.
