Fall Review - Kinematics (1D and 2D)

Front

What is the vertical velocity of a ball at its highest point when thrown straight upward?

Back

0 m/s

Front

At what point does the vertical velocity (V_y) equal 0 m/s during the motion of a thrown object?

Back

At the highest point of its trajectory.

Front

How high is a bridge if a rock is dropped from it and hits the water 20 seconds later?

Back

1960 m

Front

What distance will a freely-falling object fall in 10 seconds starting from rest?

Back

490 m

Front

What is the resultant displacement of a hiker who walks 5 km north and 7 km east?

Back

8.6 km

Front

Define kinematics in the context of physics.

Back

Kinematics is the branch of mechanics that describes the motion of objects without considering the forces that cause the motion.

Front

What is the formula for calculating the displacement of an object in one-dimensional motion?

Back

Displacement = Final Position - Initial Position.

Front

What does the term 'free fall' mean in physics?

Back

Free fall refers to the motion of an object under the influence of gravity only, with no other forces acting on it.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.8 m/s².

Front

How do you calculate the time of flight for an object thrown vertically upward?

Back

Time of flight = (2 * initial velocity) / acceleration due to gravity.
