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 determines the strength of gravitational pull between two objects?

Back

The strength of gravitational pull is determined by the mass of the objects and the distance between them.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms or grams.

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 distance affect gravity?

Back

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

Front

Why do planets closer to the Sun travel faster?

Back

Planets closer to the Sun travel faster due to stronger gravitational forces acting on them.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases.

Front

Why would a person weigh less on Mars than on Earth?

Back

A person weighs less on Mars because Mars has less mass and therefore lower gravity than Earth.

Front

What is the formula for calculating weight?

Back

Weight = Mass x Gravitational Acceleration (W = m x g).

Front

What is gravitational acceleration on Earth?

Back

Gravitational acceleration on Earth is approximately 9.81 m/s².
