FLASHCARD QUESTION

Front

What force do free-falling objects fall under the influence of?

Back

Force of gravity.

2.

FLASHCARD QUESTION

Front

What does the value g = -9.8 m/s² represent?

Back

The acceleration due to gravity on Earth.

3.

FLASHCARD QUESTION

Front

Calculate the maximum vertical height reached by a coin if it is tossed upward at a velocity of +20 m/s.

Back

+20 m.

4.

FLASHCARD QUESTION

Front

If a free-falling object takes 10s to travel upward, what is the total time the object is in the air?

Back

20s because of symmetry; T_up = 10s, T_down = 10s, so T_total = 20s.

FLASHCARD QUESTION

Front

How long is a coin in the air if it is tossed upward at a rate of +20 m/s?

Back

4 s.

FLASHCARD QUESTION

Front

What is the formula for calculating the height of an object in free fall?

Back

h = v_i * t + 0.5 * g * t², where h is height, v_i is initial velocity, g is acceleration due to gravity, and t is time.
