1.2 Free Fall

Front

What happens to the velocity of a baseball thrown up into the air as it rises?

Back

The velocity decreases.

Front

What is the speed of a freely falling object after falling for 6 seconds from rest?

Back

60 m/s.

Front

In which direction is the velocity of a baseball thrown up into the air?

Back

Upward.

Front

Do a leaf and a stone fall with different accelerations in a vacuum?

Back

They would accelerate at the same rate.

Front

What is the acceleration of a ball moving upward in free fall?

Back

The ball has constant acceleration.

Front

What happens to the acceleration of a ball at the top of its path in free fall?

Back

The ball has constant acceleration.

Front

What is the acceleration of a ball moving downward in free fall?

Back

The ball has constant acceleration.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

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

Back

v = g * t, where v is speed, g is acceleration due to gravity, and t is time.
