Free Fall Concepts and Problems

Front

What is the acceleration due to gravity on Planet X?

Back

8 m/s²

Front

If a rock is thrown upward at 40 m/s on Planet X, what will be its velocity after 6 seconds?

Back

-8 m/s

Front

What happens to the speed of an object dropped from rest as it falls?

Back

The speed increases.

Front

What does a dot diagram represent in the context of free-falling objects?

Back

It shows the position of the object at equal time intervals.

Front

What is the acceleration due to gravity on Planet Doofenshmurtz?

Back

4 m/s²

Front

If you throw a stone straight upward on Planet Doofenshmurtz, what is the speed at which you must throw it to catch it 10 seconds later?

Back

20 m/s

Front

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

Back

v = u + at, where u is the initial velocity, a is the acceleration, and t is the time.

Front

What is the significance of a negative velocity in free fall?

Back

It indicates that the object is moving downward.

Front

How does the time of flight relate to the initial velocity and acceleration in free fall?

Back

Time of flight can be calculated using the formula t = (v - u) / a.

Front

What is the effect of gravity on the motion of a free-falling object?

Back

Gravity causes the object to accelerate downward.
