Energy and Waves

Josh and Heather were at the bowling alley. Josh decided to take careful aim at the front bowling pin and roll the ball slowly down the lane. Heather decided to take careful aim and roll the ball as fast as she could. Which strategy for knocking down the most pins do you agree with and why.

• Josh because rolling it slowly, he will be more careful.

• Heather because the faster the bowling ball travels the stronger the force is when it collides with the pins.

• Josh because rolling it slowly he will be more accurate.

• Heather because the faster the ball has less energy.
