Free-Fall Review 1

Front

What is free fall?

Back

Free fall is when an object is only experiencing the force of gravity.

Front

What is the formula to calculate the height of an object in free fall?

Back

Height (h) = 0.5 * g * t^2, where g is the acceleration due to gravity and t is the time in seconds.

Front

What is the value of g on Earth?

Back

The acceleration due to gravity on Earth is approximately -9.8 m/s².

Front

How long does it take for an object to fall from a height of 44 m?

Back

It takes approximately 3.0 seconds to fall from a height of 44 m.

Front

What is the velocity of a ball dropped after 4 seconds?

Back

The velocity of a ball dropped after 4 seconds is 40 m/s.

Front

If a coin is tossed upward at +20 m/s, what is its maximum height?

Back

The maximum height reached by the coin is +20 m.

Front

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

Back

The velocity of an object in free fall increases by approximately 10 m/s every second.

Front

What is the difference between weight and mass?

Back

Weight is the force due to gravity acting on an object, while mass is the amount of matter in an object.

Front

What is the relationship between mass and free fall?

Back

In free fall, all objects accelerate at the same rate regardless of their mass.

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.
