Force and Inertia Game

A force is a push or pull upon an object resulting from the object's interaction with another object. Inertia is the resistance of any physical object to any change in its state of motion. The relationship between force and inertia is that the more force applied to an object, the more it can overcome its inertia and change its state of motion. In the following game, push the button to move the hockey stick. While you are pushing down the stick, a constant force is applied to the hockey puck. When you release the Push button, you are no longer applying force to the puck. Your job is to make the puck stop as close to the finish line as possible.

Note that while the game shows the stick and the ball being detached, in reality, the stick and the ball should be in contact as long as you are applying force.

Score: 0 / 100

Discussion Questions

  1. What's the relationship between duration of force applied and the distance travelled?
  2. What's the relationship between duration of force applied and velocity? Between the force applied and acceleration?
  3. Which Newton's laws are relevant in understanding the motion of the puck?
  4. After you release the button, the stick is no longer pushing the puck. The puck starts to decelerate. What is making the stick decelerate? How does this relate to inertia?
  5. Use a screen recording app to record one good game where your score is between 90 and 100. Review the recording and make a table of value between time from the moment you push the Push button and the velocity. Draw a line of best fit. Plot the velocity against time. Look up the mass of a standard hockey puck and using your graph to find out the average force applied by the hockey stick.
