Vertical Motion

Free fall is condidered:

• Horizontal Motion

• 2 Dimension Motion

• Vertical Motion

• an accident

In a vertical motion, what does positive velocity mean?

• That is constant

• A body moving downwards

• A body moving upwards

• That is a constant displacement

The interaction between a moving object and the molecules in the air, it opposes the downward motion of a falling object

• Gravity

• Acceleration due to Gravity

• Free Fall

• Air resistance

What does the "y" represents in the follwing formula ?

Vf ² = Vi² + 2ay

• Velocity in the y axis

• displacement

• inertia

• air resistance

Why is acceleration in the vertical motion a constant?

• due to inertia

• due to gravity

• due to air resistance

• due to magnetism

What is the constant acceleration due to gravity?

• • - 8.9 m/s²

• • 9.8 m/s²

• • - 9.8 m/s

• • - 9.8 m/s²

Who was the first Phycisist having thought of concepts of Gravity ?

• Isaac Newton

• Galileo Galilei

• Aristotle

• Galilei Newton

What is the difference between Kinematics and Dynamics?

• Motion

• what causes motion

• Constant acceleration

• No good answer

• In our experiment of dropping 4 balls different size and mass what happened?

• The heavier ball hit the ground first.

• The lighter ball hit the ground first.

• All the balls hit the ground at the same time.

• All the balls hit the ground at different time.

Why is acceleration due to gravity represent as a negative number ?

• Because it a vector and it's going down

• I don't know

• Because it's opposite to the velocity .

• All of the previous answers.
