Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is weight?

Back

Weight is the force of gravity acting on an object, calculated as the mass of the object multiplied by the acceleration due to gravity.

Front

What is mass?

Back

Mass is the amount of matter in an object, which does not change regardless of the object's location.

Front

How does gravity change with distance?

Back

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

Front

What unit is used to measure weight?

Back

Weight is measured in Newtons (N).

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases, assuming the gravitational field strength remains constant.

Front

Where would you weigh less but not lose mass?

Back

You would weigh less on the Moon due to its weaker gravitational pull compared to Earth.

Front

What is the force of gravity on Earth?

Back

The force of gravity on Earth is approximately 9.8 m/s².

Front

What happens to an object's weight in space?

Back

In space, far from any massive body, an object's weight approaches zero, but its mass remains unchanged.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by the drag force of the medium through which it is falling.
