free body diagrams

Front

What is a free body diagram?

Back

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

Front

What does the normal force do?

Back

It acts perpendicular to the surface and supports the weight of an object resting on it.

Front

What is weight force?

Back

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

Front

Define frictional force.

Back

The force that opposes the relative motion of two surfaces in contact.

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 that opposes the weight of an object immersed in it.

Front

How does the normal force change on an inclined plane?

Back

The normal force decreases as the angle of inclination increases, calculated as N = mg cos(θ).

Front

What is the relationship between normal force and weight force on a flat surface?

Back

On a flat surface, the normal force is equal to the weight force (N = W).

Front

What factors affect frictional force?

Back

The nature of the surfaces in contact and the normal force acting between them.
