Gravity

Front

What is the SI unit used to measure force?

Back

The SI unit used to measure force is newtons.

Front

Who is credited with the law of universal gravitation?

Back

The law of universal gravitation is credited to Isaac Newton.

Front

Which system has the greater gravitational pull between two objects?

Back

The system with the greater gravitational pull is determined by the mass of the objects and the distance between them.

Front

What happens to gravitational attraction if one object has less mass?

Back

Less mass equals less gravitational attraction.

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

How does distance affect gravitational force?

Back

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

Front

What is the relationship between mass and gravity?

Back

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

Front

What is the formula for gravitational force?

Back

The formula for gravitational force is F = G * (m1 * m2) / r^2, where F is the 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 weight?

Back

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

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².
