  • Why does the water stay in the cup when turned upside down?

    When you flip the water glass over in this experiment, the water in the glass is pulled down by gravity. But, the force of the water pushing down is lower than the force of atmospheric pressure, which is pushing up on the card. That’s why the water stays in the glass. Water molecules like to […]

  • What is a vertical spring-mass system?

    In other words, a vertical spring-mass system will undergo simple harmonic motion in the vertical direction about the equilibrium position.

How do you find the […]

  • Why do we ignore air resistance in physics?

    Air resistance is insignificant for heavy objects precisely because it doesn’t depend on the mass. This is because a force is just an interaction that tries to change the momentum of an object, and the momentum depends on the mass; the larger the mass, the larger the momentum, and the more force you need to […]

  • Which falls faster heavy or light?

    Answer 1: Heavy objects fall at the same rate (or speed) as light ones. The acceleration due to gravity is about 10 m/s2 everywhere around earth, so all objects experience the same acceleration when they fall. Why doesn’t a whole brick fall faster than half a brick? A whole brick has more mass than half […]
