Pull-Back Cars

Students can plan and conduct an investigation using the Pull-Back Cars to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.

Students can make observations and/or measurements of the Pull-Back Cars motion to provide evidence that a pattern can be used to predict future motion.

Students can plan and conduct an investigation using the Pull-Back Cars 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.

Using the Pull-Back Cars, students can develop an investigation and model to describe that when the arrangement of objects interacting at a distance change, different amounts of potential energy are stored in the system.

Students can plan and conduct an investigation using the Pull-Back Cars to use mathematical representation to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.

Students can use the Pull-Back Cars to test a design, build, and redefine a devise that works with given constraints to convert one form of energy into another form of energy.
