Question

what is force and pressure ???​

Answer 1

$\huge\underline\mathrm\purple{Answer}$

Force

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Pressure

Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure is the pressure relative to the ambient pressure. Various units are used to express pressure.

Answer 2

Explanation:

• Given,
• Given,Given,Mass =5 kg
• Given,Given,Mass =5 kgGiven,Mass =5 kgVelocity =4m/s
• Given,Given,Mass =5 kgGiven,Mass =5 kgVelocity =4m/sGiven,Mass =5 kgVelocity =4m/sNet force will be 0 . This is because an object moving with a uniform speed has zero acceleration, there is no change in velocity.
• Given,Given,Mass =5 kgGiven,Mass =5 kgVelocity =4m/sGiven,Mass =5 kgVelocity =4m/sNet force will be 0 . This is because an object moving with a uniform speed has zero acceleration, there is no change in velocity.Given,Mass =5 kgVelocity =4m/sNet force will be 0 . This is because an object moving with a uniform speed has zero acceleration, there is no change in velocity.And according to Newton's second law of motion, we know, Acceleration is directly proportional to Force.
