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 2

objects "fall" toward the center of the earth.

objects travel at a rate of 9.8 m/s toward the center of the earth.

Step-by-step explanation:

Gravity is the force of a body of mass that pulls other objects towards it.

Center of Gravity

The force of gravity always comes from the center of the body. So, when objects on Earth are affected by gravity, they fall towards the center of Earth. This is the center of gravity for the planet.

Pull of Gravity

The strength of a body's gravity is based on its mass. The more mass something has, the more pull it will have. This means that objects on Earth do have some pull on Earth; however, it is much weaker because the objects on Earth have less mass.

Speed and Acceleration

The Earth pulls towards its center, so objects fall towards the center at the rate of gravity. On the other hand, objects can accelerate across the planet at any rate, like how cars accelerate at different speeds.

The average pull of Earth's gravity is 9.8 m/s. So, this is how fast objects fall to the center of the Earth.
