Force
Q1: What is Force?
Answer:
To Push Or Pull an object is defined as the force. Force is the interaction between two objects that tend to change the state of the object.
Q2: What is the SI unit of force?
Answer:
The SI unit of Force is Newton. One Newton is defined as the force applied when one kg object accelerates with 1 m/s2
Q3: What force is friction?
Answer:
Friction is a contact force which acts only when two objects are in contact with each other. It is an opposing force i.e. it always opposes the motion of the object.
Q4: What can force do?
Answer:
Force can do various things such as,
- Force can change the direction of the object.
- Force can change the state of rest or motion.
- force can change the speed of the object.
- Force can change the shape and size of the object.
Q5: How many types of forces are there on the basis of interaction?
Answer:
On the basis of interaction between two objects force can be categorised into two categories,
- Contact Force
- Non-Contact Force
Q6: Which is the weakest force in nature?
Answer:
Among all the fundamental forces “Gravitational Force” is the weakest force and is also considered to be the weakest force in nature.
Q7: Is force a scalar quantity?
Answer:
Force is not a scalar quantity. Since it has both direction and magnitude. Therefore, force is a vector quantity.
Q8: An apple falls from a tree, which force is responsible for these phenomenon?
Answer:
Force of gravity is responsible for the fall of the apple. The Force of gravity is the force of attraction between the earth and any object.
Force
Force is defined as an external cause that a body experiences as a result of interacting with another body. Whenever two objects interact, a force is exerted on each object.
In general-term “To Push or Pull an Object” is defined as the force. The force is the interaction experience by the object because of the other object. Generally, force applied to an object changes its state of rest or motion and it also adds acceleration to the object.
