PushPull strollerleash swingwagon kite string What could be added to the chart to fill in the blank? A. a toy on a string B. opening a refrigerator door C. closing a zipper D. a wheelbarrow

B. Incorrect – You pull to open a refrigerator door. C. Incorrect – You pull to close a zipper. D. Correct – You push to move a wheelbarrow. A. Incorrect – You pull a toy on a string.

Two toy cars were on identical ramps. When pushed by a science student, car A traveled 20 cm and car B traveled 25 cm. What conclusions can you draw? A. Car B was pushed harder than Car A. B. Car A was pushed harder than Car B. C. The lighter colored car would travel further. D. The darker colored car would travel further.

B. Incorrect – Car A did not travel as far as Car B. It could not have been pushed harder. C. Incorrect – The color of the car does not affect the distance. D. Incorrect – The color of the car does not affect the distance. A. Correct – Car B traveled 5cm further than Car A. The force of the push would have been harder for identical cars to travel different distances.

A_________________________________B What force would move the plastic car from point A to point B? A. Push or pull B. Magnetic C. Gravity D. Friction

A. Correct – The force of a push or pull would move the car from point A to point B. B. Incorrect – Magnetic force would not move a plastic car. C. Incorrect – Gravitational force would not move a car from side to side. D. Incorrect – Friction would provide resistance as the car moved from point A to point B.
