Question

Define the following.

1) Drag

2) Vibration

3) Pressure




fast​

Answer 1

Explanation:

DRAG

pull (someone or something) along forcefully, roughly, or with difficulty.

Vibration

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The word comes from Latin vibrationem. The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.

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.

Answer 2

drag

pull (someone or something) along forcefully, roughly, or with difficulty.

"we dragged the boat up the beach"

vibration

an inst ance of vibrating.

"powerful vibrations from an earthquake"

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 (Force per unit area). Unit of pressure is Pascals (Pa).
