Worked Example
Compare the energy transferred when a 1 kg ball rolls at 2 m/s versus 4 m/s into a bowling pin:
1
Recall kinetic energy relation to speed
Kinetic Energy increases exponentially with speed (KE ~ v²)
Doubling the speed quadruples the kinetic energy.
2
Evaluate comparative collision energy
4² / 2² = 16 / 4 = 4 times more energy
The ball rolling at 4 m/s carries 4 times as much kinetic energy.
3
State physical consequence
Pin is displaced significantly farther
Greater kinetic energy does more mechanical work during the collision.
✓Verification Check
Does higher velocity result in greater collision transfer?
Speed = 4 m/s
•
Energy is 4x greater (Verified)
⚠️ Common Pitfalls & Misconceptions
Thinking stationary objects contain kinetic energy
✗ Thinking a stopped ball has motion energy✓ Kinetic energy requires motion; motionless objects have potential or thermal energy
Kinetic energy specifically describes energy of mass in motion.
