Energy and Motion

A faster ball knocks over more pins. Why? Learners gather evidence that the faster an object moves, the more energy it has, using a ramp simulation and collision data. They trace where the energy goes when objects collide (into the motion of the other object, sound and a little warming), predict collision outcomes and write an explanation that connects speed and energy.

What learners will discover

  • Use evidence to explain that the faster an object moves, the more energy of motion it has.
  • Describe and predict the energy changes that happen when objects collide, including transfer to the other object, sound and heat.
  • Construct an explanation from investigation data that relates an object's speed to its energy.
