Forces Flashcard

Front

What is the normal force?

Back

The normal force is the support force exerted by a surface perpendicular to the object resting on it.

Front

What is the force of gravity?

Back

The force of gravity is the downward force exerted on an object due to its mass, commonly referred to as weight.

Front

What is the relationship described by Newton's second law?

Back

Newton's second law states that the net force (Fnet) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a), expressed as Fnet = m.a.

Front

What does Newton's first law state?

Back

Newton's first law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is frictional force?

Back

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

Front

What is tension force?

Back

Tension force is the pulling force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

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 air resistance?

Back

Air resistance is a type of frictional force that acts against the motion of an object moving through air.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is equilibrium?

Back

Equilibrium is the state in which the net force acting on an object is zero, resulting in no acceleration.
