Explain what is force with examples .
Answers
A force involves an interaction between two or more objects, and it causes a push or pull between the objects.Good examples of opposing force include drag due to interaction with an air mass and the force due to friction between two objects.
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.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
Contact Force
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
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.
Solved Force Examples
Q.1) How much net force is required to accelerate a 1000 kg car at 4.00 m/s2?
Solution:
Given,
a = 4.00 m/s2
m = 1000 kg
Therefore,
F = ma
= 1000 × 4
= 40Examples of contact forces are:
