Review actions and reaction forces. Determine interaction which occurs when a cannon fires a cannon ball. Determine why the interactions are not equal, as should be by Newton's 3rd law. If force equals mass x acceleration, then acceleration equal force/mass. The cannonball exhibits a large force and small mass while the cannon exhibits a small force and a large mass. The forces remain equal, the acceleration changes. Introduce systems. Determine why a force must be applied outside the system in order for motion to occur. The forces will not cancel each other when opposing the system. Use examples to explain why.

Review speed formula a distance/time. Discuss two types of speed, instantaneous and average speed. Differentiate between the two. Elicit that both speeds involve rate. . Define velocity as speed in a direction. Define constant velocity and show examples. Introduce the concept of acceleration.

Discuss force and air resistance. Elicit how air resistance depends on velocity and area. Elicit how air resistance is directly proportional to speed and frontal area. Define terminal speed and how acceleration becomes zero at terminal speed and the velocity becomes constant. introduce force interactions, action force and reaction force. Discuss friction as the force necessary for motion. Redefine force in terms of mass and acceleration. Note that acceleration is directly proportional to the force and inversely proportional to the mass. Demo action/reactions forces using a balloon.

Lab designed to predict the landing point of projectile. Lab involves determining both vertical and horizontal distance and time for a projectile moving along a ramp and then dropping to the floor. Determine horizontal distance and time from appropriate formulas as well as vertical speed and distance. After all measurements and calculations are completed, the exact location of the projectile of the golf ball rolling down the ramp and landing into a cup on the floor is determined and then executed.

Motion lab to determine average speed, distance traveled during a specific period of time and at a specific average speed. Utilize speed and distance formulas.

Review parts of Newtons second law as well as fee fall and formulas involved with free fall. Examine Newton's third law. Discuss force as a push or pull. Elicit why you do not fall through the wall if you lean on it. Discuss the action force and the Force of reaction, use examples. State Newton's 3rd law in terms of action and reaction forces. Discus examples of actin and reaction forces in everyday life

Define motion as being relative. Elicit how even when not moving, motion is relative to something. This may be the Earth's surface, or road, or the Sun. Define that an object is moving if its position relative to a fixed point is changing. Speed is relative to the Earth's surface. Elicit the definition of speed in terms of distance and time. Discuss instantaneous speed and average speed. Define speed as distance/time and discover that instantaneous speed will change momentarily.

Review acceleration formula which relates velocity to time and acceleration of gravity. Review formula to determine distance in free fall. Examine the relationship which exists between force, mass, and acceleration. Discuss the effect of area and force on pressure exerted. Explain free fall using the relationship between force and mass. As mass increases during free fall, the acceleration remains the same, 9.8 msl^2.

State Newton's law of inertia. Demonstrate using mass and dynamics chart the effect suddenly stopping motion has on an object. Note both the effect on motion from rest and the effect from motion to rest. Examine and discuss the effect of mass on inertia, increased mass increases inertia.
Define volume and and differentiate mass from volume.. Demonstrate how increases in volume do not necessarily relate to increases in inertia. Outline units of measurement.

Review the cause add effects of friction. Describe the effects friction has on moving objects and the need to apply a constant force to keep an object moving. Diagram the affect a rolling mass will have on the height reached when the objet moves down a ramp and then up the other side. Show that as the ramp becomes elongated on the return side, the mass reaches a higher return point. Elicit what would occur if the return ramp was infinite. Determine that the mass would roll indefinitely until stopped gy an external force.
