1
Q

Define weight Fg

A

Fg is the gravitational force the Earth exerts on any object on or near its surface.

Weight is a vector quantity and is dependent on the local gravitational field strength.

Q

Define normal force FN

A

FN is the perpendicular force exerted by a surface on an object in contact with it.

The normal force acts perpendicular to the contact surface.

Q

Define frictional force Ff

A

Ff is the force that opposes the motion of an object.

Frictional force can vary based on the surfaces in contact and the normal force.

Q

How does the frictional force act in relation to the surface?

A

The frictional force acts parallel to the surface with which the object is in contact.

This characteristic is essential for understanding the mechanics of motion and resistance.
