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 the normal force do?

Back

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

Front

What is friction?

Back

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

Front

In which direction does friction act when an object is moving up a ramp?

Back

Down the ramp, opposing the motion.

Front

What is tension?

Back

The force exerted by a rope or string when it is pulled tight.

Front

What is weight force?

Back

The force due to gravity acting on an object, directed downward.

Front

What is a spring force?

Back

The force exerted by a compressed or stretched spring, proportional to its displacement.

Front

What is buoyant force?

Back

The upward force exerted by a fluid on an object submerged in it.

Front

What is the difference between static and kinetic friction?

Back

Static friction prevents motion between surfaces at rest, while kinetic friction acts on moving surfaces.

Front

What is the role of a free body diagram in solving physics problems?

Back

It helps identify all the forces acting on an object, making it easier to apply Newton's laws.
