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!

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
P = mv
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
The standard unit of measurement for force
