Gravity

Front

What are the two factors affecting the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

Why does a ball fall to the ground?

Back

Earth's force of gravity is GREATER than the ball's, so the ball gets attracted to the ground.

Front

What changes with different gravitational forces?

Back

Weight.

Front

Does gravity attract all objects towards one another?

Back

True.

Front

Does any object with mass have gravity?

Back

True.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between them.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

How does distance affect the force of gravity?

Back

As the distance between two objects increases, the force of gravity between them decreases.

Front

What is the formula for calculating gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two masses.

Front

What is the gravitational constant (G)?

Back

A constant used in the calculation of gravitational force, approximately equal to 6.674 × 10^-11 N(m/kg)^2.
