Exploring the Moon: Distance, Gravity, and Physics

How do scientists measure the increasing distance between the Earth and the Moon?

• Using satellite imagery

• By calculating the moon's shadow on Earth

• Using reflectors left on the Moon by astronauts

• By observing the moon's orbit through telescopes

What is the effect of the Moon moving away from the Earth?

• It causes the Earth to spin faster

• It shortens the length of a day

• It increases the Earth's gravitational pull

• It lengthens the duration of a day

Why would a person weigh less on the Moon compared to Earth?

• The Moon's surface is smoother

• The Moon has less mass than Earth

• The Moon has a stronger gravitational pull

• The Moon is closer to the Sun

What happens when a hammer and a feather are dropped simultaneously on the Moon?

• The hammer lands first due to its weight

• Neither lands due to low gravity

• Both land at the same time due to lack of air resistance

• The feather lands first due to its shape

Who predicted that objects would fall at the same rate in a vacuum?

• Isaac Newton

• Albert Einstein

• Galileo Galilei

• Stephen Hawking
