Differentiate Between Contact and Non-contact Forces
Force refers to the push and pull which is applied to any object when it meets the other object and this interaction leads to a change of state, which can be either of rest or uniform motion. It is of 2 types:
- Contact forces
- Non-contact forces
The difference between contact and non-contact forces are:
CONTACT FORCES | NON CONTACT FORCES |
Contact force refers to the process in which physical contact is required to move the object. It can be continuous and helps to change the position of the object. | Non-contact force refers to the process in which the object is made to change its position but without any physical contact made by anybody to the object. |
It occurs because of the contact which takes place between 2 different types of objects. | It does not involve any type of contact between the 2 objects. It occurs because of attraction or repulsion which is done between the 2 objects. |
In contact forces, the field is not linked. | In non-contact forces, the field is always linked. |
Examples of contact forces are:
- When we ride a bicycle
- An airplane that is flying through the air.
- When we pass a football to a receiver.
- When we pitch the baseball to the batsman.
- When a skydiver jumps to the ground and opens his parachute while being in the air.
Examples of non-contact forces are:
- An apple after ripening falls from the tree. This is one of the best examples of non-contact forces.
- Electromagnetism is also referred to as an example of non-contact forces.
- During rain, the raindrops when falling to the ground is also termed as a non-contact force.
- When the leaves fall from the tree.
