FreeFall

Front

What is free fall?

Back

Free fall is the state that exists when the only force acting on an object is gravity.

Front

Do objects of different masses fall at the same rate in a vacuum?

Back

Yes, both objects fall with the same acceleration regardless of their mass.

Front

What happens to an object in free fall on the Moon?

Back

It would not encounter any air resistance.

Front

If air resistance is ignored, how do objects of different masses behave when dropped?

Back

They fall with equal accelerations and with equal displacements.

Front

What is the acceleration of free falling objects near the Earth's surface?

Back

Falling objects accelerate at -9.8 m/s².

Front

What is the effect of air resistance on free falling objects?

Back

Air resistance opposes the motion of falling objects, reducing their acceleration.

Front

What is the difference between free fall and projectile motion?

Back

Free fall is solely influenced by gravity, while projectile motion involves both gravity and an initial velocity.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of air resistance equals the force of gravity.

Front

How does gravity affect free fall on different celestial bodies?

Back

The acceleration due to gravity varies on different celestial bodies, affecting the rate of free fall.

Front

What is the formula for calculating the distance fallen in free fall?

Back

Distance = 0.5 * g * t², where g is the acceleration due to gravity and t is time.
