Do this Write the claim of the video clip. Write the evidence use to support the claim. Tell how the evidence supports the claim. Tell why the evidence support the claim.

Leading questions. What is the main point of the video? What three things are involved? Does force affect acceleration? Examples of how force affected acceleration? How was the claim shown by big and little hits to the puck?

Claim Acceleration equals force divide by mass. If force is increased, acceleration will increase.

Evidence With a hard hit, the puck receives a large force and it accelerates a lot. With a little tap the puck receives a small force and it accelerates a little.

Reasoning (The words Since and So will help you communicate your reasoning) The harder the puck is hit, the more it accelerates, so acceleration will increase as force increases. This shows a cause and effect relationship.

(Also, acceleration will decrease if mass increases. The puck's mass doesn’t change so this is not addressed in the video)
