What is the unit used by scientists to measure forces like gravity?

Back

Newtons are the unit used to measure forces, including gravitational force.

Front

What happens to your weight if Earth's mass is cut in half?

Back

Your weight would decrease because gravitational force decreases.

How does changing the distance of the string in a model represent the orbits of planets?

Back

The longer the string, the longer the orbit time of a planet.

Front

Which system has greater gravitational attraction between two objects?

Back

System B has greater gravitational attraction.

Front

Which system has greater gravitational pull between two objects?

Back

System 2 has greater gravitational pull.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses.

Front

What factors affect gravitational force?

Back

Gravitational force is affected by the masses of the objects and the distance between them.

Front

What is the formula for 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 weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

How does mass affect weight?

Back

Weight increases with mass; more mass means more gravitational force acting on it.
