Description
Today, students took part in the infamous Car-Pushing Lab (see the video here). They took turns pushing my car across a 20 meter track. Using a stopwatch, they timed each pusher. Then they calculated acceleration using the a=2d/t2 formula, plugged in the mass of my car (1,350 kg), and calculated the force of each pusher.
The lessons included how to use Newton’s 2nd Law, that increasing the number of pushers will increase the force, and that increasing the mass of the car (everybody jump in!) will reduce the acceleration.

NGSSMS-PS2-2
Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object. Emphasis is on balanced (Newton’s First Law) and unbalanced forces in a system, qualitative comparisons of forces, mass and changes in motion (Newton’s Second Law), frame of reference, and specification of units. Assessment is limited to forces and changes in motion in one-dimension in an inertial reference frame, and to change in one variable at a time. Assessment does not include the use of trigonometry.
NGSSMS-PS2-1
Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects. Examples of practical problems could include the impact of collisions between two cars, between a car and stationary objects, and between a meteor and a space vehicle. Assessment is limited to vertical or horizontal interactions in one dimension.
