Free Fall and Motion

Front

Define Displacement

Back

The vector quantity that gives the straight line distance from starting position to ending position.

Front

Define Acceleration Due to Gravity

Back

The constant acceleration on an object because of gravitational force; on Earth it is about 10 m/s².

Front

What is the acceleration of a ball that is dropped off the side of a cliff after 1,2,3,4,5 seconds? (assume g is rounded to 10 m/s²)

Back

10, 10, 10, 10, 10 m/s².

Front

Define Scalar Quantity

Back

A quantity that is fully described by the magnitude and does not have a direction.

Front

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

Back

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude, while vector quantities have both magnitude and direction.

Front

What is the value of acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

If an object is in free fall, what is its initial velocity?

Back

The initial velocity is 0 m/s if dropped from rest.

Front

What happens to the speed of an object in free fall as time increases?

Back

The speed increases due to the constant acceleration of gravity.

Front

What is the maximum height reached by an object thrown upwards?

Back
