Free Fall & Vertical Launch

A stone falls from the rest of the roof of a building, points out the right thing:

• its speed remains constant and so does its acceleration

• its speed increases as its acceleration increases

• its speed remains constant and its acceleration increases,

• its speed increases and its acceleration remains constant

A stone is thrown vertically upwards, neglecting friction, points out the right thing:

• the time it takes to go up is greater than the time it takes to go down

• the speed at which you go up is greater than the speed at which you go down

• the time it takes to go down is less than the time it takes to go up

• the speed with which it goes up is equal in magnitude to the speed of descent

An apple falls freely from the second floor of a room, points out the correct thing:

• has a movement in which it travels equal distances in equal times

• with each time interval the magnitude of the distance traveled decreases

• with each time interval the magnitude of the distance traveled increases

• the distance traveled when falling varies according to the mass of the object

A stone is dropped from the roof of a building, it points out the right thing:

• has maximum speed at the highest site

• its speed increases at every instant of time

• its acceleration is constantly increasing in magnitude

• its acceleration is zero all the way

Regarding the acceleration experienced by a falling book and neglecting friction, we can affirm that it is:

• maximum at highest site

• zero just before hitting the floor

• from zero to the highest place

• constant throughout the tour

When an object falls freely the acceleration at the highest point is zero

• True

• False

As an upward thrown object rises, its acceleration remains constant

• True

• False

An object that is thrown vertically upwards in the highest place its speed is maximum

• True

• False

An object that falls from a certain height its speed is maximum at the lowest place

• True

• False

In vertical movement, the time it takes to raise the object is less than the time it takes to lower

• True

• False
