Thursday, April 9, 2015• 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?

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
