Free Fall

Front

What happens to an object in free fall in the physics world?

Back

It accelerates at a constant rate until it hits the ground.

Front

What is the acceleration of a ball in free fall as it rises, at the top of its path, and as it falls?

Back

The ball has constant acceleration as it moves upward, at the top of its path, and as it moves downward.

Front

If a freely falling object starts from rest, what will its speed be after falling for 6 seconds?

Back

About 60 m/s.

Front

How do the initial velocity (Vi) and final velocity (Vf) compare in a free fall problem?

Back

Vi and Vf are the same in magnitude, but different in vector.

Front

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

Back

They would hit the ground at the same time.

Front

What is the acceleration due to gravity (g) near the Earth's surface?

Back

Approximately 9.81 m/s².

Front

What is terminal velocity?

Back

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

What is the difference between mass and weight in the context of free fall?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the formula to calculate the speed of a freely falling object after a certain time?

Back

Vf = Vi + g*t, where Vf is final velocity, Vi is initial velocity, g is acceleration due to gravity, and t is time.

Front

What is free fall?

Back

The motion of an object under the influence of gravitational force only.
