What is a Free-Body Diagram?

Back

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

Front

What are the two main factors that determine the amount of friction between two objects?

Back

Force and roughness between surfaces.

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 frictional force?

Back

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

Front

What is an example of harmful friction?

Back

Engine parts wearing out due to excessive friction.

Front

What is balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is unbalanced force?

Back

Forces that are not equal and opposite, resulting in a change in motion.

Front

What is weight force?

Back

The force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

What is thrust?

Back

The force that propels an object forward, often used in the context of engines or rockets.

Front

What is buoyant force?

Back

The upward force exerted by a fluid that opposes the weight of an object immersed in it.
