Question

1. Define pressure.
2. Write all the effects of force.
3. A force of 200N is applied to an object of area 4 m². Evaluate pressure.​

Answer 1

Define pressure

• Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area.
• The basic formula for pressure is F/A

Write all the effects of force

• A force can move a stationary object.
• A force can stop a moving object.
• A force can change the speed of a moving object.
• A force can change the direction of a moving object.
• A force can change the shape and size of an object.

• Define pressure.

Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.

• Write all the effects of force.

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. When there's the interaction between two objects they exert a force on each other, these exerted forces are equal in size but opposite in direction.

________________________________

• A force of 200N is applied to an object of area 4 m². Evaluate pressure.

Force → 200N

Area → 4m²

Pressure → $\small{\boxed{\sf{{Force/Area}}}}$

→ [ 200/4 ] N/m²

→ $\small{\boxed{\sf{{50 N/m²}}}}$
