Question

Short answer questions - 2 marks 1. Define pressure 2. How do fluids exert pressure? 3. A force of 100 N is applied on an area of 4 m2. Compute pressure being applied on the area. 4. What are the effects of force on an object?

Answer 1

Answer:

1. The force acting on a surface is called the pressure. When the area of contact increases pressure decrease

2. The particles of fluids are constantly moving in all directions at random. As the particles move, they keep bumping into each other and into anything else in their path. These collisions cause pressure, and the pressure is exerted equally in all directions.

3.p=f/a

so,f=100N and a=4m ^2

100/4 n/m^2

25n/m^2

4. A force acting on an object causes the object to change its shape or size, to start moving, to stop moving, to accelerate or decelerate

PLEASE MARK ME BRAINLIEST

Answer 2

Answer:

1.)force per unit area is known as pressure...

2.)fluids exerts pressure normal to the surface of container it is contained...

3.) pressure=force/area=100/4=25 Pascal

4.) force is something which can:-

i) can cause motion of an object

ii) change shape of an object.
