Topic 6 and 7 Vertical and Projectile Motion

Is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity that follow a parabolic path.

• Vertical Motion

• Free Fall

• Projectile Motion

• Uniform Accelerated Motion

How many motion components does the projectile motion has ? and what are the names of them ?

• 3 components direction, south and north

• 4 acceleration, velocity, time and direction

• 2 components, Horizontal and Vertical Motion

• There is no a good answer.

In a projectile Motion:

How is the acceleration in the X component ?

• It is constant due to gravity -9.8 m/s²

• It is constant due to no change in velocity

• There is no acceleration in the X component

• Time is constant

In a projectile Motion:

How is the acceleration in the y component ?

• Varies during the time of the thorw

• There is no any acceleration in the y component

• It's constant due to gravity -9.81 m/s²

• Time is always constant

True or False: Vertical motion and horizontal motion are linked together by time

• True

• False

How is velocity in x component during the parabolic path?

• Always the same magnitud and sense.

• It changes during the path.

• Same magnitud different sense

• Different magnitude same sense

How is velocity in y component during the parabolic path?

• It is always the same

• It decreases in the positive sense till the max hieght and then increases in the opposite sense

• It is always the same but with opposite sense

• There is no good answer

Which is the physical quality that link vertical motion and horizontal motion together ?

• acceleration due to gravity

• Final Position

• time

• initian velocity

What path should a horizontal projectile motion follow?

• parabolic

• semi parabolic

• horizontal line

• diagonal path

In what manner does projectile motion is similar to the free fall ?

• because of the time

• Both reach a highest point and then go down due to gravity .

• Both are throws

• There is no a correct answer.
