Front

The measure of the pull of gravity on an object is ___________________.

Back

Weight.

Front

What variable do 'Newtons' represent?

Back

Force.

Front

What is the psychological illusion of heaviness called?

Back

Apparent Weight.

Front

What is Newton's Law of Universal Gravitation?

Back

It states that every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is the formula for 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.

Front

What does the gravitational constant (G) represent?

Back

It is a proportionality constant used in the equation of Newton's Law of Universal Gravitation, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two masses increases, following an inverse square relationship.

Front

What is weight?

Back

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