Question

3. How can you differentiate between a contact force and and a force at a distance
​

Answer 1

Answer:

Contact force are done by the physical contact between our body and an object. Example, muscular force and frictional force.

Non- Contact force are done from a distance between our body and an object. Example, magnetic force, electrostatic and gravitational force

Answer 2

Explanation:

DIFFERENCE BETWEEN CONTACT FORCE

AND

DISTINCT FORCE (non contact force)

CONTACT FORCE :

Occurs due to physical contact between two forces.

Can be continous or just impulsive(short duration)

More common and occur in day to day life.

Mainly 3 types of contact force.,

*Frictional force

*applied force

*frictional force

Some of the Examples are,

*kicking any substance

*pushing anything

* physically sliding on suface

NON CONTACT FORCES

Occures without the physical contact of between two forces.

More often in microscopic and universal level.

Mainly 4 types

*Gravitational force

*Electromagnetic force

*Strong nuclear forces

*Weak nuclear forces

Some of examples are,

*Gravity between earth and moon

*collusion between electrons

*magnetic forces
