Free Fall and Acceleration

Front

What happens to the velocity of a baseball as it rises in the air?

Back

The velocity decreases.

Front

In Newtonian physics, what is any motion of a body where gravity is the only force acting upon it?

Back

Free fall.

Front

What kind of motion does a distance-time graph with a straight line represent?

Back

Constant Speed.

Front

Does free fall take into consideration the frictional force of air resistance?

Back

False.

Front

What happens to the acceleration of a baseball as it rises in the air?

Back

The acceleration remains constant.

Front

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

Back

Approximately 9.81 m/s².

Front

What is the term for the force that opposes the motion of an object through air?

Back

Air resistance.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the effect of air resistance on a falling object?

Back

It reduces the acceleration and can lead to terminal velocity.
