What is force?Explain with its types.
Answers
Answer:
what is force?
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).
Types of Force
Force is a physical cause that can change the state of motion or the dimensions of an object. There are two types of forces based on their applications:
- Contact Force
- Non-Contact Force
Forces that act on a body either directly or through a medium are called contact forces.
Examples of contact forces are:
- Muscular Force
- Mechanical Force
- Frictional Force
We can make use of the muscular force of animals like bullocks, horses, and camels to get the activities done. The frictional force is another type of contact force, which acts between a pair of a surface in contact and tends to oppose the motion of one surface over the other.
Non-Contact Force
Forces that act through spaces without making direct contact with the body are called non-contact forces.
Examples of non-contact forces are:
- Gravitational Force
- Electrostatic Force
- Magnetic Force
The force exerted by a magnet on other magnets is called magnetic force. Magnetic force and electrostatic force act on an object from a distance, that’s the reason they are non-contact forces. The strength of gravity is an attractive force that is exerted by the Earth on objects, which make them fall to the land. The weight of a body is the force that is pulled by the earth towards the center.
pls make me as Branilist
Answer:
A force is a push or pull acting upon an object as a result of its interaction with another object. ... Previously in this lesson, a variety of force types were placed into two broad category headings on the basis of whether the force resulted from the contact or non-contact of the two interacting objects.
