U4 Q2

Front

What is the normal force?

Back

The normal force is the force exerted by a surface that supports the weight of an object resting on it, acting perpendicular to the surface.

Front

What is frictional force?

Back

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

Front

What is applied force?

Back

Applied force is a force that is applied to an object by a person or another object.

Front

What is spring force?

Back

Spring force is the force exerted by a compressed or stretched spring, proportional to the displacement from its equilibrium position.

Front

What is tension?

Back

Tension is the force exerted by ropes, strings, or cables when they are pulled tight.

Front

What is weight force?

Back

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

Front

What is buoyant force?

Back

Buoyant force is 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 thrust?

Back

Thrust is the force that propels an object forward, commonly associated with engines or propellers.

Front

What is elastic force?

Back

Elastic force is the force exerted by an elastic material when it is stretched or compressed, returning to its original shape.

Front

What is the relationship between normal force and weight force?

Back

In a static situation on a horizontal surface, the normal force is equal in magnitude and opposite in direction to the weight force.
