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

What happens to gravitational force as mass increases?

Back

As mass increases, the gravitational force also increases.

Front

What is the force of gravity acting on an object called?

Back

The force of gravity acting on an object is called its weight.

Front

How does distance affect gravitational force?

Back

The farther apart two objects are, the weaker their gravitational attraction.

Front

What is the relationship between mass and weight?

Back

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

Front

What is the formula for calculating gravitational force?

Back

The formula is 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

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2, a key value in the formula for gravitational force.

Front

What is weight measured in?

Back

Weight is measured in newtons (N).

Front

What is the effect of gravity on objects in free fall?

Back

In free fall, all objects accelerate towards the Earth at the same rate due to gravity, approximately 9.81 m/s².

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
