Why did Emily Dickinson write poetry
Emily Dickinson wrote poetry to express her feelings about the
outside world.
When can the equations of kinematics not be used
Equations of kinematics or equations of motion can not be used
when the body is not accelerating or is moving with a constant
velocity.
What name is given to the rate at which velocity changes
During an inquiry activity You can use one or more of your five senses during an inquiry activity to make
When an object in free fall is dropped from a building Its starting velocity is 0 ms Ignoring the effects of air resistance what is the speed in ms of the object after falling 3 seconds
What can be defined as the rate at which velocity changes
acceleration
The rate at which velocity changes is called "acceleration".
A natural force of attraction exerted by the earth upon objects that pulls objects towards earth's center is called
When a cup of water is dropped as the cup falls the water in the cup falls out
the answer is true not false
Given no air resistance all objects near the Earth's surface regardless of size and weight fall with the same acceleration because of gravity
Why is a sheet of paper falls slowly than crumples one
Because the flat sheet of paper has greater air resistance
Velocity can be defined as what in a given direction
Velocity is speed in a given direction.
As the space shuttle orbits the Earth the shuttle and the astronauts accelerate towards the Earth with the same acceleration What effect does this create
What vector is created by pointing in a particular direction
Which of the following are not vector directions?
What three very different sizes and weights are dropped off a tower on the moon Which factor of the objects will determine which hits the ground first
Assuming that each object is held with its center of gravity at
the same height, and that each is dropped cleanly, with no rotation
induced, the one whose lowest part is closest to the ground when
dropped will hit first.
The acceleration of gravity means that for each second that passes falling objects move 98 meters
No, that's not correct.
The acceleration of gravity means that for each second that passes, falling objects fall
at a speed that's 9.8 meters per second fasterthan it was one second earlier.
Whih of the following is not a reason why gravity is important in our lives
It keeps water molecules together in a cup.
What is a practical example of gravity acting on a moving object
A car speeds up as a traffic light turns green.
Which of the following can be used to explain a statement in a geometric proof Check all that apply
Corollary.
Theorem.
Definition.
Postulate.
