Explanation:
about force. We use the word force daily, and force has become a common word rather than a scientific word. So let us first know what a force is.
What is Force?
The push or pull experienced by an object with the mass that causes the velocity is called force. 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.
Formula and SI Unit
The quantity of force is expressed by the product of mass (m) and acceleration (a). Mathematically the equation can be written as
F = ma
Where,
F= Force
m = mass
a = acceleration
When a force acts on an object the objects, the things have different effects of force. So let us know about the impact of force on an object.
Following are the effects of force on an object
Force can set a stationary object in motion:
When force is applied to a stationary object, the object tends to move in the direction in which force is applied. For example, applying force on a stationary tennis ball will make it continue its motion in the direction of applied force.
.
For example, when you pick up a book placed on the table using your hands, you apply muscular force. It is the force that is exerted by the Earth on every object, which is near or on its surface. For example, an apple falling from a tree branch towards the ground is due to gravitational force...
