The measure of the pull of gravity on an object:

• Volume

• Mass

• Buoyancy

• Weight

The closer to the Earth's surface an object is, the stronger gravity pulls on it.

• True

• False

Answer explanation

True. Gravity is stronger closer to the Earth's surface due to the inverse square law, which states that gravitational force increases as distance decreases.

The reason planets orbit stars and moons orbit planets is

• Gravity or gravitational pull

• Magnetism

• Space is big

• Mr. Scott makes them

Answer explanation

The correct answer is 'Gravity or gravitational pull' because it is the force that causes planets to orbit stars and moons to orbit planets, keeping them in stable paths around each other.
