Explanation

Bernoulli’s principle is based on conservation of energy in flowing fluids.

P+1/2 ρv2+ρgh=constant

For airplane wings:

• P = Pressure
• ρ (rho) = Density of air
• v = Speed of air
• g = Gravitational acceleration
• h = Height
• Higher air speed → Lower pressure
• Lower air speed → Higher pressure
• Pressure difference between the upper and lower surfaces creates lift.
• Lift acts upward and helps the airplane fly

Explanation

• Earth’s gravity provides the force that keeps satellites in orbit.
• This gravitational force pulls the satellite toward Earth.
• The satellite’s forward motion makes it continuously fall around Earth rather than directly into it.
• Newton’s Law of Gravitation explains this gravitational attraction.

• The pitch of a sound wave depends on its frequency.
• Pitch tells us whether a sound is high or low.
• Higher frequency → higher pitch (e.g., whistle).
• Lower frequency → lower pitch (e.g., bass drum).
• Frequency is measured in Hertz (Hz).
