Students are investigating changes from potential to kinetic energy by rolling a marble down a ramp made by propping up a plastic ruler on a book and letting it roll down. Which of the following will change the potential energy the marble starts with?

The illustration shows a rollercoaster and indicates four different positions the car might be at as it moves along the track. At which point in the rollercoaster’s journey is its potential energy the greatest?

At which position does the pendulum have the most kinetic energy?

A box and forces are shown below. A box rests motionless on the ground. One student is pushing the box to the right with a force of 2 Newtons. The other student is pushing to the left with a force of 5 Newtons. In which direction and with what type of speed will the box move?

The simplified graph shows the motion of an object as measured and recorded in consistent units of time and distance. From the graph, it can be concluded that the object was moving -

Time and distance data for a bicycle is provided in the graph. According to the data in the graph, what was the average speed of the bicycle?

John left his home and walked 3 blocks to his school, as shown in the accompanying graph. What is one possible interpretation of the section of the graph from point B to point C?

The diagram shows an investigation in a science classroom. Students pull the same mass up an inclined plane propped up on five blocks, then six, seven, and eight blocks. Each time, they use a spring scale to measure the force needed to pull the mass up the inclined plane. This investigation can show how which of the following affects the force needed to move an object up an inclined plane?
