The equation F = ma is one of the most important in physics. Yet we have so far not explained how to get a quantitative operational definition of either mass or force. Somehow, from this one ...

Isaac Newton's First Law of Motion states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." What, then, happens to a body ...

The terms weight and mass are often used incorrectly. Phrases like ‘a bag of sugar weighs 1 kg’ are not scientifically correct. This means that a 1 kg mass would be attracted to Earth by a force of 10 ...

There are many physics exercises related to the game of baseball, which involve solving and calculating different parameters from objective data. Ball speed, energy, forces, distance, mass, angles and ...

For the total mass of each glider, calculate the value of \(\frac{1}{\text{mass}}\). For example, 100 g has a mass of 0.1 kg. The value of \(\frac{1}{\text{mass}}\) is \(\frac{1}{0.1}\) = 10 /kg. Plot ...

If you push an ordinary ball, it moves away from your hand. No surprise there. But if you pushed a ball with negative mass, it would actually accelerate backwards, moving towards you instead. It might ...
