• Do Now: Greg is interested in building a rocket that will
fly vertically the greatest distance. After research, he
determines that the fins of the rocket have the
greatest affect on altitude, but is unsure what shape is
best. Identify the following elements of a proposed
science experiment he could design to answer his
question:
– Question
– Variables
– Type of Graph?
Today’s Goals:
• Forces and Motion Review BINGO!
• We will stop occasionally to
elaborate/expand/practice and discuss
• Winner (s) get a prize!

Here We
Go!
A push or a pull
Shows the change in an object’s
location from its reference point over a
period of time.
PAUSE and PRACTICE!
Unequal push or pull applied to an
object that results in motion
The direction and speed of an object
with motion
The combined amount of force acting
on an object
PAUSE and PRACTICE!
An opposing force that acts to slow
objects in motion, stop objects in
motion or prevent motion
An object’s point of origin (where it
starts) before motion; the ZERO on a
distance-time graph
A graph that illustrates how fast/slow
an object is moving over a period of
time
PAUSE and PRACTICE!
Law of motion: there is a relationship
between force, mass and acceleration;
F=ma; the amount of force required to move an
object increases as the mass of the object
increases; the acceleration of an object
decreases as its mass increases
Law of motion: for every action, there
is an equal and opposite reaction
The natural tendency for an object to
resist a change in motion
The formula for calculating speed
PAUSE and PRACTICE!
The amount of force required to make an
object move or to stop an object in motion
The force that causes an object to
follow a circular path
The change in an object’s velocity over
a given period of time
PAUSE and PRACTICE!
What is the car’s
acceleration?
the equal amount of applied force and
opposing force acting on an object
that results in no motion
Law of motion: an object in motion,
stays in motion and an object at rest
stays at rest, UNLESS acted upon by an
outside force
The formula used to calculate force;
shows the relationship between force, mass and
acceleration
PAUSE and PRACTICE!
The force of attraction between
objects; pulls them together;
increases as distance decreases; increases as
mass increases
Negative acceleration; object’s speed
is decreasing
How fast or slow an object is changing
location over a given period of time
(movement)
PAUSE and PRACTICE!
1. What is the
Red runner’s
average
speed?
2. Which
runner is
slower?
The movement of an object; object
changes location
How far an object moves away from its
original location; NOT = distance
traveled
