Free Fall and Acceleration

Front

What is free fall?

Back

Free fall is any motion of a body where gravity is the only force acting upon it.

Front

Does free fall take into consideration air resistance?

Back

No, free fall does not take into consideration the frictional force of air resistance.

Front

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

Back

Free-falling objects accelerate at approximately 10 m/s².

Front

What happens to the velocity of an object in free fall?

Back

The velocity of an object in free fall increases at a uniform rate.

Front

If a feather and a metal bolt are dropped from the same height in a vacuum, which hits the ground first?

Back

They would hit the ground at the same time.

Front

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

Back

Air resistance slows down the acceleration of free-falling objects, but in a vacuum, there is no air resistance.

Front

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

Back

The distance fallen can be calculated using the formula: d = 0.5 * g * t², where g is the acceleration due to gravity and t is the time in seconds.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

Front

How does mass affect free fall in a vacuum?

Back

In a vacuum, all objects fall at the same rate regardless of their mass.

Front

What is the difference between free fall and projectile motion?

Back

Free fall occurs when an object is only influenced by gravity, while projectile motion involves an initial velocity and the influence of gravity.
