In Physics Class Carrie Learns That a Force.

Aristotle famously represented a strength as anything that causes an object to undergo “unnatural motion”. Sir Isaac Newton was one of the first scientists to study gravity and strength. Any kind of force is just a push or a pull. It can be described as a push button or pull on an object.

What is Force?

What is Force?

Push or pull of an object is considered a force. Push and pull come from the objects interacting with i another. Terms similar stretch and squeeze can also exist used to denote force.
In Physics, force is defined as:

The push or pull on an object with mass causes information technology to change its velocity.

Strength is an external agent capable of changing a body’s country of rest or motion. Information technology has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force, and the awarding of force is the point where force is practical.

The Force tin exist measured using a bound residue. The SI unit of measurement of strength is Newton(N).

Common symbols: F→, F
SI unit: Newton
In SI base units: kg·m/s2
Other units: dyne, poundal, pound-force, kip, kilo swimming
Derivations from other quantities:  F = thou a
Dimension: LMT-2

What are the Effects of Force?

In physics, motion is divers as the change in position with respect to fourth dimension. In simpler words, motion refers to the movement of a body. Typically, movement tin can either be described as:

  1. Change in speed
  2. Change in direction

The Strength has different effects, and here are some of them.

  • Forcefulness can make a body that is at rest to move.
  • It tin can finish a moving torso or slow it downwardly.
  • It can accelerate the speed of a moving trunk.
  • It can also change the direction of a moving torso along with its shape and size.

Formula for Force

The quantity of force is expressed by the vector product of mass (k) and acceleration (a). The equation or the formula for forcefulness can mathematically be expressed in the grade of:


  • thou = mass
  • a = acceleration

It is articulated in Newton (N) or Kgm/southii.

Acceleration a is given by

= v/t


  • five = velocity
  • t = time taken

So Force can be articulated as:

= mv/t

Inertia formula is termed as
p = mv

which can too exist articulated as

Therefore, Force can be articulated every bit the rate of change of momentum.

= p/t = dp/dt

Force formulas are benign in finding out the strength, mass, acceleration, momentum, velocity in whatever given problem.

Unit of Force

  • In the centimeter gram second arrangement of unit (CGS unit) force is expressed in
  • In the standard international system of unit (SI unit) it is expressed in
    Newton (N).

Types of Force

Strength is a physical cause that can change an object’due south state of motion or dimensions. There are ii types of forces based on their applications:

  1. Contact Forcefulness
  2. Non-Contact Force
