Free Fall 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

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

How far does an object fall in the first 5 seconds of free fall?

Back

An object falls approximately 122.5 meters in the first 5 seconds of free fall.

Front

If an object is in free fall for 3 seconds, how fast will it be falling?

Back

After 3 seconds, the object will be falling at approximately 29.4 m/s.

Front

What is the formula to calculate the velocity of a free-falling object?

Back

The formula is v = g * t, where v is velocity, g is acceleration due to gravity (9.81 m/s²), and t is time in seconds.

Front

What happens to the speed of a free-falling object as it falls?

Back

The speed of a free-falling object increases as it falls due to the constant acceleration of gravity.

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.

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.

Front

How does mass affect free fall?

Back

In free fall, all objects accelerate at the same rate regardless of their mass, assuming air resistance is negligible.

Front

What is the significance of the 9.81 m/s² acceleration?

Back

9.81 m/s² is the standard acceleration due to gravity at Earth's surface, affecting all freely falling objects.
