Force is an external cause that can alter the state of the body when applied. Due to force, a moving object comes to rest, or an object at rest starts moving.
Here in this post, we will explore the term "Force" used in Physics. This will definitely help to understand the basics of NEET Physics.Common Terms and Description | |
---|---|
Terms | Description |
Symbol | "F" |
SI Unit | Newton (N) |
Definition | Interaction causing a change in motion |
Type | Vector Quantity |
Magnitude and Direction | Yes |
Newtons's Second Law | ( F = m*a ) |
Common Forces | Gravitational, Electromagnetic, etc. |
Measurement Device | Force Gauge |
Effect on Motion | Acceleration, Deceleration, Rest |
Examples | Pushing a car, Gravity on an object |
Restoring Force | Elastic forces |
Interaction Medium | Can act through a vacuum |
Interaction Range | Can be short-range or long-range |
F = m * a
Where, F - Represents force, measured in newtons (N). It signifies the interaction causing a change in the object's state of motion or shape. M - Stands for mass, measured in kilograms (kg). It quantifies the amount of matter in an object, determining its resistance to acceleration. a - Denotes acceleration, measured in meters per second squared m/s 2 . It signifies the rate at which an object's velocity changes, influenced by the applied force. In a nutshell, the force acting on an object is directly proportional to its mass and the rate at which its motion changes (acceleration).How can an applied force change the shape of an object | ||
Force | Application | Examples |
Compressive Force | Application of force pushing inward | Squeezing a stress ball compresses its shape |
Tensile Force | Application of force pulling outward | Stretching a rubber band elongates its shape |
Shear Force | Application of force pulling outward | Sliding one layer of a deck of cards relative to another |
Torsional Force | Application of twisting or rotational force | Twisting a wet towel to wring out water |
Bending Force | Application of force causing curvature. | Bending a plastic ruler |
