The formula to calculate elastic force is F_el = k * ΔL, where k is the elastic constant and ΔL is the elongation.

The spring constant k measures a spring's stiffness, calculated by k = F_el / ΔL.

The gravitational force acting on an object is calculated by F_g = m * g, where m is mass and g is gravitational acceleration.

Converting units is essential for calculations, e.g., 1 cm = 0.01 m.

The general formula for force is F = m * a, where m is mass and a is acceleration.

The amount of matter in an object, measured in kilograms (kg).

The acceleration due to gravity near Earth's surface, approximately 10 m/s².

The force exerted per unit area, calculated as P = F / A.

The force exerted by an object due to its mass and gravity, calculated as F = m * g.

Mass per unit volume, often expressed in kg/m³.

The pressure exerted by the weight of the atmosphere, typically 100,000 Pa at sea level.

Pressure exerted by a fluid at equilibrium due to the force of gravity, often calculated as Phid + Patm.

The difference between final and initial lengths, important for calculating spring properties.

Pressure ($P_{hid}$) can be calculated from fluid height ($h$) and gravity ($g$).

The resultant force ($F_{rez}$) is the total of individual forces acting on an object: $F_{rez} = F_1 + F_2 + F_3$.

A larger force can be broken down into component forces.

Finding the component of a force vector ($F$) from a resultant force ($F_{rez}$).

In equilibrium, the sum of forces acting on a body is zero.

The force resisting motion between two surfaces in contact, calculated as Ftr = µ * F.

A dimensionless constant representing the frictional interaction between surfaces, noted as 0.6 in the problem.

The combined force of multiple weights at different distances, calculated as Wtotal = W1 * d1 + W2 * d2.

The gravitational force acting on an object, measured in Newtons (N), e.g., W1 = 14 N and W2 = 12 N.

The resultant force acting on an object, calculated as F2 = total force - other forces.

The sum of the forces exerted by mass and gravity.

The force of gravity acting on an object's mass on the moon.

The resistance force that opposes motion between two surfaces.

Force exerted by a spring, calculated as F_el = k * ΔL.

The acceleration due to gravity, typically 9.8 or rounded to 10 N/kg.

F = ρ × g × h × A calculates force using density, gravity, height, and area.

0.7 cm³ converts to 0.7 × 10⁻⁶ m³ for force calculations.

ρ = mass/volume, essential for calculating buoyancy and force.
