What one is faster and why?

Answer Interesting question - It reminds me of the one often asked in high school Physics class, "Which is heavier, feathers or lead?". The students always answer with lead. Then the teacher states that... Read More »

Top Q&A For: What one is faster and why

When you drop a baseball and a bowling ball, you say that its velocity acts faster and faster as it falls. How can you say that the acceleration is constant at 9.8 m/s2 If it is falling faster and faster wouldn't the acceleration change also until th?

It's very important to distinguish velocity from acceleration. Acceleration is caused only by forces, so while a ball is falling freely it is accelerating according to gravity alone. In that case i... Read More »

Will 1 byte travel faster on a faster network?

The bits of data all travel at the same speed down a communications link. If there is no processing along the way then they travel at a bit under the speed of light, about 300,000,000 metres per se... Read More »

You insist over and over again that it is impossible to go faster than the speed of light. This is completely and entirely untrue. Tachyons travel faster than light. They also go faster as they exert less and less energy. — K?

I'm afraid that you confuse the hypothetical with the actual. While people have hypothesized about superluminal particles called tachyons, they have never been observed and probably don't exist. Th... Read More »

As the Space Shuttle falls, does it accelerate forever and does it go faster and faster?

Yes to the first part, no to the second part. Remember that acceleration can change the direction of velocity without changing the magnitude of velocity (the speed of the object). When the space sh... Read More »
