What type of movement is represented in the picture?
Straight movement

Curvilinear movement
Parabolic movement
What is a frame of reference?
The trajectory of a moving object.

The distance traveled by a moving object.
Read the situation: "When you're sitting on the bus, you move in relation to an observer (1) that is on the street, but you do not move in relation to another observer (2) who is in the bus." What does this example show about movement?
That movement is always the same.
That movement is relative.
That movement is an absolute magnitude.
None of them
Read the situation: "When you're sitting on the bus, you move in relation to an observer (1) that is on the street, but you do not move in relation to another observer (2) who is in the bus" What is the point of reference of the observer (1)?

Which picture represents the net force equals zero?
A
B
C
D
What is represented in picture D?
An undefined deformation
A temporary deformation
An inertia state of matter
None of them
In picture B, how is the force applied?
In the same direction and opposite sense of the movement
In the same direction and sense of the movement
Forces are in balance.
In different direction and the same sense of the movement
What happens in picture C?
The force is applied in the same direction
and opposite sense of the movement.
The forces are in balance.
The force is applied in the same direction
and sense of the movement.
The object starts moving.
How would you describe the relationship between
mass and movement?
More mass the body has, more movement.
Less mass the body has, less movement
More mass the body has, less movement.
They are not related.
What is the meaning of the mass quantifies the inertia?
The more mass a body has, the easier to move or stop it.
More mass, more gravity attraction a body has.
The more mass a body has, it is more difficult to move or stop it.
The less mas a body has, more difficult to move or stop it.
