Gravitational Forces

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects with mass. It pulls objects toward each other, and its strength depends on the masses of the objects and the distance between them.

Front

What two factors affect gravitational force?

Back

Mass and Distance.

Front

How does mass affect gravitational force?

Back

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

Front

How does distance affect gravitational force?

Back

The greater the distance between two objects, the weaker the gravitational force between them.

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.

Front

What happens to weight on different planets?

Back

Weight varies on different planets due to differences in gravitational force.

Front

What is the relationship between mass and weight?

Back

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

Front

What is escape velocity?

Back

Escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a planet or moon.

Front

What is the gravitational pull of Earth?

Back

Earth's gravitational pull is approximately 9.81 m/s².

Front

What is the effect of gravity on falling objects?

Back

Gravity causes objects to accelerate towards the Earth at a rate of 9.81 m/s², regardless of their mass.
