The circuit closes and allows electricity to flow.
Maggie is pushing a box filled with books to her room. She has to push very hard to get the box to move. Why is the box difficult to move?
The box of books has a large mass and requires more force to move.
The students are doing an experiment to see which of 4 toy cars goes the farthest down a ramp. The ramp is the same height for each car. The force applied to each car is the same. The cars are all different shapes. What would be the variable in this experiment.
