8. Centripetal Forces & Gravitation

At what height above the earth is the free-fall acceleration 10% of its value at the surface?

The acceleration due to gravity is approximately $10\text{m}/{\text{s}}^2$. Why does the seconds unit appear twice in the denominator?

What is the standard value of the acceleration due to gravity near the Earth's surface?

What is the approximate value of the acceleration due to gravity on the surface of the Moon?

What is the approximate value of the acceleration due to gravity for an object in free fall near the surface of the $Earth$?

The acceleration due to gravity on Earth is $9.8m/s^2$. What is the weight of a $75\mathrm{kg}$ person on Earth?

What is the approximate value of the free-fall acceleration at the surface of the Sun?

What is the approximate value of the free-fall acceleration due to gravity at the surface of the Moon?

What is the approximate value of the free-fall acceleration due to gravity at Earth's surface?

What is the standard value of acceleration due to gravity on the surface of Earth?

What is the acceleration due to gravity on the surface of the Moon (in $m/s^2$)?

The acceleration due to gravity is approximately $10m/s^2$. Why does the unit second appear twice in the denominator?

What is the approximate value of the acceleration due to gravity on the surface of the Earth?

A particle is released at a height r_E (radius of Earth) above the Earth’s surface. Determine its velocity when it hits the Earth. Ignore air resistance. [Hint: Use Newton’s second law, the law of universal gravitation, the chain rule, and integrate.]

What is the approximate acceleration produced by Earth's gravitational force on objects near its surface?
