Get Gravity And Motion Worksheet Answer Key 2020-2025

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

Gravity is affected by the size of an object and the distance between the objects. When the mass of an object increases the force of gravity increases as well. If an object's weight is greater than the other object's weight, then the object with the greater weight will land first.

On Earth, the weight of the body (like any other object) is given by Newton's laws as mass times gravitational acceleration (w = m * g). That is, the weight of an object is determined by the pull of gravity on it.

Originaly defined by Newton, and refined by Einstein, gravity is essentially the natural force of attraction between any two objects. Two factors determine the magnitude of the gravitational force between two objects: (1) their masses and (2) the separation distance between them.

Expert-Verified Answer The force that holds the gases in the sun. It causes a ball thrown in the air to come down again. It causes a car to coast downhill even when you aren't stepping on the gas. It causes a glass you drop to fall on the floor.

The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases. Both objects exert an equal attractive force on each other: a falling object is attracting the Earth with the same size force as the Earth is attracting it.

The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.
