What is a Free Body Diagram (FBD)?

Back

A graphical representation used to visualize the forces acting on an object. It shows all the external forces acting on the object, represented by arrows.

What is the normal force?

Back

The force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What is the role of frictional force in motion?

Back

Frictional force opposes the relative motion between two surfaces in contact, affecting the acceleration of the object.

Front

What is tension force?

Back

The force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is gravitational force?

Back

The force of attraction between two masses, commonly experienced as the weight of an object due to Earth's gravity.

Front

How do you determine the net force acting on an object?

Back

The net force is the vector sum of all the forces acting on the object. It determines the object's acceleration according to Newton's second law.

What is the condition for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, meaning all forces are balanced.
