Total questions: 40
Worksheet time: 40mins
A change in speed over a given period of time is
velocity
motion
speed
acceleration
What is the formula to calculate speed?
Speed = time + distance
Speed = distance/time
Speed = distance x time
Speed= time - distance
A textbook is dropped from a second floor window and falls to the ground. What happens to the velocity as the book falls to the ground
the velocity increases
the velocity decreases
the velocity remain constant
A baseball is thrown up into the air. What happens to the velocity as the ball rises in the air?
the velocity increases
the velocity decreases
the velocity remains constant
A baseball is thrown up into the air. What happens to the acceleration as the ball rises in the air?
the acceleration increases
the acceleration decreases
the acceleration remains constant
The standard acceleration due to gravity (or standard acceleration of free fall),is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is defined by standard as:
9.8 m/s.
9.8 m.
9.8 m/s2.
9.8 s.
In Newtonian physics, ________________ is any motion of a body where gravity is the only force acting upon it.
kinematics
free fall
mechanics
velocity
Which of the following graphs best represents free fall motion?
A deer running 15 meters per second due west
If a 50-N person is to fall at terminal speed, the air resistance needed is
50 N
More than 50N
Less than 50N
There is not air resistance in nonfreefall
As the skydiver in FREEFALL falls faster and faster through the air, ACCELERATION
increases
decreases
stays the same
