Question

2 types of force with examples explain
​

Answer 1

The two types of forces are

• Contact force
• Non - contact force

Examples of contact forces include:

• Reaction force. An object at rest on a surface experiences reaction force . ...
• Tension. An object that is being stretched experiences a tension force. ...
• Friction. Two objects sliding past each other experience friction forces. ...
• Air resistance.

Examples of Non-Contact Force:

• An apple falling down from a tree is one of the best examples of non-contact force.
• Iron pins attracted in the presence of a magnet bar without any physical contact.
• Falling of raindrops on earth is also an example of non-contact force.

Answer 2

Answer:

Gravitational Force and applied force

Gravitational force is an attractive force that can be defined by Newton’s law of gravity which states that ‘gravitational forces between two bodies are directly proportional to the product of their masses and inversely proportional to the square of the distance between them’. It is a force exerted by large bodies such as planets and stars.

Example: water droplets falling down

applied force --When you push a table across the room, you apply a force that acts when it comes in contact with another object. This is ‘applied force’;

i.e. a force that is applied to a person or object.
