Free Fall

Front

What is free fall?

Back

Free fall is any motion of a body where gravity is the only force acting upon it.

Front

What is the acceleration of a free-falling object near the Earth's surface?

Back

The acceleration of a free-falling object near the Earth's surface is approximately -9.8 m/s².

Front

What happens to the acceleration of an object in free fall as it falls?

Back

The acceleration remains constant at -9.8 m/s².

Front

What does the slope of a velocity-time graph represent?

Back

The slope of a velocity-time graph represents the acceleration of the object.

Front

If an object is accelerating negatively, what does that indicate about its motion?

Back

It indicates that the object is slowing down.

Front

What is the difference between velocity and speed?

Back

Velocity is a vector quantity that includes direction, while speed is a scalar quantity that does not.

Front

What is the formula for calculating the distance fallen during free fall?

Back

The formula is d = 0.5 * g * t², where g is the acceleration due to gravity and t is the time in seconds.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by the drag force acting against it.

Front

How does mass affect the acceleration of a free-falling object?

Back

In free fall, all objects accelerate at the same rate regardless of their mass.

Front

What is the significance of the negative sign in the acceleration of free fall?

Back

The negative sign indicates that the acceleration is directed downward, towards the center of the Earth.
