SUMMARY

The discussion centers on the relationship between mass, speed, and kinetic energy, specifically comparing a golf ball and a Ping-Pong ball with equal kinetic energy. According to the formula for kinetic energy, KE = 1/2 M*V^2, a higher mass (golf ball) results in a lower speed compared to a lower mass (Ping-Pong ball) when both have the same kinetic energy. Therefore, the golf ball must move slower than the Ping-Pong ball to maintain equal kinetic energy levels. This conclusion is established through the direct application of the kinetic energy formula.

PREREQUISITES
  • Understanding of kinetic energy formula (KE = 1/2 M*V^2)
  • Basic knowledge of mass and velocity concepts
  • Familiarity with the principles of physics related to motion
  • Ability to perform algebraic manipulations
NEXT STEPS
  • Study the implications of mass and velocity in different physical contexts
  • Explore the concept of momentum and its relation to kinetic energy
  • Investigate real-world applications of kinetic energy in sports physics
  • Learn about energy conservation principles in collisions
USEFUL FOR

Physics students, educators, sports scientists, and anyone interested in the mechanics of motion and energy transfer.

If a golf ball and a Ping-Pong ball both move with the same kinetic energy, can you say which has the greater speed? Explain in terms of the definition of kinetic energy.

Can you guys tell me if I'm thinking along the correct lines in my response...

Kinetic energy = 1/2 M*V^2.
Since the golf ball has a higher mass than the pingpong ball, the only way they could both have the same kinetic energy is if the golf ball has a slower speed.

Correct!

K, thanks...haha I'll try to keep these questions to a minimum when they're so simple but it was so simple I felt like I was overlooking something haha
