Free body diagrams 2

Front

What is a free-body diagram?

Back

A graphical representation used to visualize the forces acting on an object.

Front

What does it mean when forces are balanced in a free-body diagram?

Back

It means that the net force acting on the object is zero, resulting in no acceleration.

Front

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 weight force?

Back

The force due to gravity acting on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W = mg).

Front

What is frictional force?

Back

The force that opposes the motion of an object in contact with a surface.

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 spring force?

Back

The force exerted by a compressed or stretched spring, described by Hooke's Law (F = -kx).

Front

What is buoyant force?

Back

The upward force exerted by a fluid on an object submerged in it, equal to the weight of the fluid displaced by the object.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest, while kinetic friction acts on an object in motion.
