Front

What is the magnitude of the object's total displacement after 8.0 seconds?

Back

0 m

Front

A clam dropped by a seagull takes 3.0 seconds to hit the ground. What is the seagull's approximate height above the ground where the clam was dropped?

Back

30 m

Front

Which of these dot diagrams represents a free falling object dropped from rest?

Back

D

Front

What is Newton's First Law?

Back

An object at rest stays at rest, and an object in motion stays in motion.

Front

If the block in the picture has an acceleration of 1 m/s², what would be the block’s mass?

Back

2 kg

Front

What is Newton's Second Law of Motion?

Back

F = ma (Force equals mass times acceleration)

Front

Define displacement in physics.

Back

Displacement is the vector quantity that refers to the change in position of an object.

Front

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

Back

h = 0.5 * g * t², where g is the acceleration due to gravity and t is time.

Front

What does a dot diagram represent in motion?

Back

A dot diagram represents the position of an object at equal time intervals.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².
