Force and Pressure

Water pressure increases with depth because the weight of the water above increases as you go deeper.

A barometer is the standard scientific instrument used to measure atmospheric pressure.

Pressure is force divided by area. The force is 10 N. The area of one side of a 1m cube is 1m * 1m = 1 square meter. Pressure = 10 N / 1 m^2 = 10 Pa.

The Pascal (Pa) is the SI unit for pressure, defined as one Newton per square meter.

Pressure is defined as the force applied perpendicular to the surface of an object per unit area. Therefore, the formula is Pressure = Force / Area.

Gravitational force is the universal force of attraction that acts between all matter that has mass. It is the force that governs the motion of planets and keeps objects on Earth.

Electrostatic force is the force between electrically charged objects. When a balloon is rubbed against a sweater, it gains a charge, allowing it to stick to the sweater due to this attraction.

When two forces act in opposite directions on an object, the net force is the difference between the magnitudes of the two forces. The object will move in the direction of the larger force.

The SI unit of force is the Newton (N), named after Sir Isaac Newton. It is defined as the force required to accelerate a 1 kg mass at 1 m/s^2.

In physics, a force is defined as a push or a pull upon an object resulting from the object's interaction with another object.
