Answers
Answer:
Push or pull of an object is considered a force. Push and pull come from the objects interacting with one another. Terms like stretch and squeeze can also be used to denote force.
In Physics, force is defined as:
The push or pull on an object with mass that causes it to change its velocity.
Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force, and the application of force is the point where force is applied.
The Force can be measured using a spring balance. The SI unit of force is Newton(N).
Common symbols: F→, F
SI unit: Newton
In SI base units: kg·m/s2
Other units: dyne, poundal, pound-force, kip, kilopond
Derivations from other quantities: F = m a
Dimension: LMT-2
What are the Effects of Force?
In physics, motion is defined as the change in position with respect to time. In simpler words, motion refers to the movement of a body. Typically, motion can either be described as:
Change in speed
Change in direction
The Force has different effects and here are some of them.
Force can make a body which is at rest to move.
It can stop a moving body or slow it down.
It can accelerate the speed of a moving body.
It can also change the direction of a moving body along with its shape and size.
