 ## What is Buoyant force? Formula, Examples, Uses

If we throw some balls of different weight in a container filled with water or pond or swimming pool, we can see some balls will float and some will sink. Why this happens? This is the effect of buoyant force. Now, the question is what is buoyant force? Take another example, when we get into… ## What is viscosity in Physics? How does it work? Examples

When we pour liquids from one bottle to another bottle, it takes different times for different fluids. In general concept, water will take less time compared to syrup and honey. Because, water is thin, honey and syrup are thick. In physics, to explain this fact a special term is used –“Viscosity”. Now the question arises,… ## What is impulse in physics and how it Works?

Impulse is defined as the force multiplied by the amount of time. When a force is applied for a certain amount of time on a particle, momentum of the particle changes (if the particle moves). Simply, the impulse in physics is the effect of both forces applied and amount of time. Impulse is involved with…
