Question

Which are the effects of gravity on objects on the surface of Earth? Select 2 options.

Objects “fall” toward the center of Earth.
Objects are pulled by Earth but do not pull on Earth.
Objects accelerate at a rate of 9.8 m/s each second.
Objects travel at a rate of 9.8 m/s toward the center of Earth.
Objects pull on the Earth is much stronger than the Earth’s pull on the object.

Answer 1

Correct answers:
- Objects “fall” toward the center of Earth.
- Objects accelerate at a rate of 9.8 m/s each second.

Brief explanation:
- Gravity pulls objects toward Earth's center, so they fall downward.
- Near Earth's surface the acceleration due to gravity is about 9.8 m/s² (phrased here as 9.8 m/s each second).
The other options are incorrect because Earth and the object pull on each other equally (Newton’s 3rd law), and 9.8 m/s is a speed value, not the constant acceleration.
