Question

For freely falling objects near earth's surface, _____ is constant.

• A. acceleration
• B. speed
• C. velocity
• D. momentum

Answer 1

The correct option is A acceleration

Objects are in freefall if they are falling only under gravity. Freely falling bodies near the earth's surface gain constant acceleration called the acceleration due to gravity. For earth, the acceleration due to gravity near its surface is $9.8m/s^2$.
