Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

True or False: Gravity attracts all objects towards one another.

Back

True

Front

What happens to the pull of gravity as the distance between two objects increases?

Back

The pull of gravity decreases.

Front

What force holds all of the planets in orbit around the sun?

Back

Gravity

Front

When will the forces of gravity between two objects be the greatest?

Back

When the masses of both objects are large and the objects are close together.

Front

Why would a person weigh more on Jupiter than on Earth?

Back

Because Jupiter has more mass, and therefore more gravity.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

How does gravity affect the motion of falling objects?

Back

Gravity causes objects to accelerate towards the Earth at approximately 9.8 m/s².

Front

What is the formula for calculating gravitational force?

Back

F = G * (m1 * m2) / r², where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = m * g).
