Pressure is the force exerted on a surface per unit area.

• Pressure is a measure of how much force is applied to a given area.

• It is calculated by dividing the force applied by the area over which it is distributed.

• Pressure can be expressed in various units such as pascals, pounds per square inch (psi), or atmospheres.

• Examples of pressure include the air pressure in a tire, the water pressure in a pipe, or the blood press

Strain is the measure of deformation or elongation of a material under stress.

• Strain is a ratio of change in length to the original length of a material.

• It is measured in units of percentage or in terms of length per unit length.

• Strain can be either tensile (stretching) or compressive (shrinking).

Force is a physical quantity that describes the interaction between two objects.

• Force is measured in Newtons (N)

• It can be calculated using the formula F = m x a (force = mass x acceleration)

• There are different types of forces such as gravitational, electromagnetic, and frictional forces

• Force can cause an object to accelerate, change direction, or deform
