explain contact force and non contact force?
Answers
Explanation:
A contact force is any force that requires contact to occur. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car up a hill.
A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight.
Answer:
contact force= the force resulting due to the action of muscles is known as the muscular force.
non contact force=the force exerted by a magnet is an example of non contact force.
Explanation:
contact force =can you push or lift a book lying on a table without touching it ? can you lift a bucket of water without holding it? Generally, to apply a force on an object,your body has to be in contact with the object.
non contact force= does the magnet on the rollers begin to move when the other magnet is brought near it? does it always move in the direction of the approaching magnet? it like poles of two magnet repel each other and unlike poles attract each other.attraction or repulsion between objects can also be seen as another form of pull or push.
