Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, such as the Earth pulling objects towards its center.

Front

What does it mean to feel weightless?

Back

Feeling weightless occurs when there is no net force acting on a person, often experienced in free fall or during certain flight maneuvers.

Front

What is the significance of Polaris in astronomy?

Back

Polaris, also known as the North Star, is significant because it is located nearly directly above the North Pole and is used for navigation.

Front

What is the role of a timer in measuring time?

Back

A timer is a device used to measure the amount of time taken for an event or activity.

Front

How does distance affect the force of gravity?

Back

The force of gravity decreases as the distance between two objects increases.

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 a training flight for astronauts?

Back

A training flight is a simulated flight experience designed to prepare astronauts for the conditions they will face in space.

Front

What is the concept of free fall?

Back

Free fall is the motion of an object where gravity is the only force acting upon it.

Front

How do we measure the brightness of stars?

Back

The brightness of stars is measured in terms of magnitude, with lower numbers indicating brighter stars.

Front

What is the purpose of conducting multiple training flights?

Back

Multiple training flights help astronauts practice and become familiar with the effects of weightlessness and other conditions in space.
