Learners will plan, design, conduct, and analyze investigations using cars on ramps and balloon rockets to test how forces affect motion and energy transfer.
investigate and explain how equal and unequal forces acting on an object cause patterns of motion and transfer of energy; and
design a simple experimental investigation that tests the effect of force on an object in a system such as a car on a ramp or a balloon rocket on a string.
