Difference Between Force and Pressure

What You'll Learn?

There is often a significant difference between force and pressure, although both are physics entities. To know the difference, weâ€™d like to grasp the definition and its application. Force is that the push and pulls action leading to the change of motion and direction, whereas pressure is that the physical force per unit area.

What is Force?

Force is a very important concept because it influences motion. It will be defined as an interaction that changes the motion of an object if unopposed. But the easy definition of the force is that itâ€™s the push or pull experienced by any object. Force could be a vector quantity, thus itâ€™s both magnitude and direction. Therefore, one needs to specify both the direction and also magnitude to explain the force functioning on an object.

Types of Force

By applying force, one can make an object at rest move. This application of the force will be done either by touching the thing or by without touching the article. Therefore, there are two forms of forces:

1. Contact force
2. Non-contact force
1. Contact Force

The force is applied to the objects by bringing them into contact. There are three styles of contact forces:

• Frictional force
• Applied force
• Normal force

2. Non-Contact Force

The force which is applied to the body without coming in-tuned is thought of as a non-contact force. Gravitational force is an example of a non-contact force.

Force: Push and Pull

For instance, the force has been defined as an interaction that changes the motion of an object if unopposed. When this statement is examined closely, we see the role of push-pull during this. A force that changes the direction of an object towards you, would be a pull. On the opposite hand, if it moves away, itâ€™s a push. Sometimes, force is just defined as a push or pull upon an object resulting from the objectâ€™s interaction with another object. Hence, any reason for force may be a push or a pull. Spring and elastic also are varieties of forces. The instant you push against it, it tends to resist and react or springs back with an identical magnitude.

Push and Pull Examples

Push is defined because the force thatâ€™s chargeable for an object moving from the state of rest.

Examples of push:

1. Pushing the trolley.
2. Pushing of the car when it breaks down.
3. Pushing the table from one place to a different one.

The pull is defined because the force thatâ€™s accountable for an object moving from the state of rest but within the wrong way in comparison to the push.

Examples of pull:

1. Pulling the curtain.
2. Dragging the box.
3. Opening of the door.

What is Pressure?

Force acting upon a certain area and acted upon something perpendicular to its surface. Its unit is Pascal and is represented as Pa. The instrument to measure pressure is called a manometer. The pressure is a scalar quantity which means it does not have direction.

Pressure only acts on the surface or face of the object. Pressure on the object wonâ€™t change the direction of the object.

Difference Between Force and Pressure

Force is that the effect caused by the interaction of two objects which tries to vary the state of the thing. The pressure is that the force working on an object within the perpendicular direction to the surface of the article which ends within the spreading of force over a specific area. Therefore, if force is applied over an outsized area, then pressure is alleged to be below and if the identical force is applied to a tiny area, then the resulting pressure is claimed to be high.

Force Pressure
The push and pull action resulting in acceleration of the object Force acting upon a certain area and acted upon something perpendicular to its surface
Units
Its unit is Newton and is represented by N Its unit is Pascal and is represented as Pa
Instrument to measure
The instrument to measure force is called a dynamometer The instrument to measure pressure is called a manometer
Quantity
Force is a vector quantity which means it also has direction The pressure is a scalar quantity which means it does not have direction
Action
Force can be acted upon on the face, edges, side, or vertices of the object Pressure only acts on the surface or face of the object
Effect on object
The velocity of an object can be changed with the application of force in one direction Pressure on the object wonâ€™t change the direction of the object.
