Answer 1

Answer:

f=m*a

Explanation:

A force can be a push or a pull. When a force is exerted on an object it can change the object's speed, direction of movement or shape.

Pressure is a measure of how much force is acting upon an area.

Pressure can be found using the equation pressure = force / area. Therefore, a force acting over a smaller area will create more pressure.
