1. Learning Activity: Newton’s 2nd Law of Motion
Plan and conduct an investigation to provide evidence
that the change in an object’s motion depends on the sum
of the forces on the object and mass of the object.

Day 01: Planning
Get in groups, plan your investigation, draw a model on your white board, get your design approved.
Recommended items: chair or stool, triple-beam balance, spring-scales, meter sticks, rubber bands, golf balls, ping pong balls, baseballs, softballs etc.
Day 02: Conduct Investigation
hands-on demonstration of an object in motion accounting for an explaining the connection with the motion, the mass of the object, and the force(s) acting on the object.

2. Activity Criteria.
A) Your task is to put an object in motion by applying force to it.
An easy method is to make a sling-shot with rubber bands
stretched across the legs of a chair or stool.
B) Pick a constant: force or mass. Either the force should remain the same or the mass should remain the same each time you cause the object or objects to move.
If you use only one object (mass remains constant), cause it to
move (at least) two times w/different amount of forces each time.
If you use 2 objects (force remains constant), cause each object to move (at least) once w/the same amount of force each time.
C) Measure the distance that the object(s) travel(s).
1) Measure the mass of the object(s) (in grams).
2) Measure the amount of force (in Newtons) being applied.
3) Measure the distances (in meters or centimeters) that the object(s) travel.
