If a golf ball and a ping-pong ball both move with the same kinetic energy, which has the greater speed?.
1 answer:
Given what we know, if a golf ball and a ping-pong ball both move with the same kinetic energy, the ping-pong ball must be traveling at a greater speed.
<h3>How do we know that the ping-pong ball is faster?</h3>- This has to do with the formula for kinetic energy.
- The formula is
.
- This means that mass and velocity are proportional.
- If the total Kinetic energies are equal, the object with the lower mass must have a higher velocity.
- Since ping-pong balls are known to have very little mass, we know it must be traveling faster.
Therefore, we can confirm that if a golf ball and a ping-pong ball both move with the same kinetic energy, the ping-pong ball must be traveling at a greater speed due to its lower mass and the relationship between mass and speed when calculating kinetic energy.
