what is normal reaction force?
Don't copy from anywhere give it's own and perfect Answer....
Answers
Answer:
A force acting perpendicular to two surfaces in contact with each other. It is a measure of the force holding the two surfaces together. The larger the normal reaction force, the larger the value of limiting friction. ... Friction, therefore, is increased by increasing the weight.
Explanation:
please mark me as brainliest
Answer:
The normal force is a force of contact. When two surfaces are not in connection, a normal force can not be exerted on one another. For example, consider a table and a container, when they are not in contact not possible to exert normal force on one another. But, when two objects are touching one another, they exert normal force on one another vertical to the contacting surface. Here normal denotes to perpendicular.
