Define contact force.
Contact Force is defined as the force that comes into contact with another object.
A force that only functions when two bodies come into physical touch.
Newton's second law of motion was discussed. It claims that applying force to a body of mass ‘m' causes it to accelerate
If the mass of the body is ‘m,' and the acceleration it achieves after being subjected to force is ‘a,' then the force equation is:
F = ma
