B) 9.8 m/s2
C) 24.2 m/s2
D) 5 m/s2
List three causes of
acceleration?
If a runner starts at 2m/s and
finishes running at 10m/s over a
matter of 20s, what was that
runner’s acceleration?
If a cat goes from rest to full sprint
at 10 m/s (when attacking a mouse)
over a course of 4 seconds, what is
the acceleration?
How does gravity affect falling
objects?
Gravitational force depends on two
things. As _______ increases,
gravitational force increases.
A) Distance
B) Mass
C) Displacement
D) Velocity
The moon doesn’t fall into the earth
because it has a velocity parallel to
the earth. This is called a:
A) Maximum Velocity
B) Terminal Velocity
C) Tangential Velocity
D) Perpendicular Velocity
Which would most likely be the
acceleration due to
gravity on the Moon, if Earth’s
gravity is 9.8 m/s2?
A)10 m/s2
B)1.6 m/s2
C) 40 m/s2
D)24 m/s2
Which would most likely be the
acceleration due to gravity on
Jupiter, if Earth’s gravity is 9.8 m/s2
A) 10 m/s2
B) 4 m/s2
C) 2 m/s2
D) 24 m/s2
Gravitational force also depends
on __________. As this increases,
the gravitational force decreases.
A) Mass
B) Distance
C) Velocity
D) Acceleration
What does the speedometer
of a car read?
True or False: The moon
has less air resistance
than the Earth,
essentially acting like a
vacuum. This means a
hammer and feather
would fall at the same
rate on the moon.
Why does a hammer and feather
not fall at the same rate on Earth if
the gravitational force is the same?
Recently LIGO detected these
types of waves, resulting from the
collision of two black holes 4 billion
years ago. This proved Einstein’s
theories correct.
A flying saucer is moving
at a constant 500 mph,
but still is accelerating.
How can this occur?
What does negative acceleration
mean?
Extra 2 points:
What is it called?
If an object starts from rest, what
is it’s initial velocity?
What does the slope of this line
represent?
What does the slope of this line
represent?

A dolphin accelerates from an
initial velocity of 4 m/s for 5
seconds to catch a fish. The
dolphin’s average acceleration was
2m/s2. What velocity did the
dolphin reach?
