100

the frictional force resists force that is applied to an object

what is static friction

100
the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.

what is terminal velocity


100

a type of physical interaction that occurs between electrically charged particles.

what is electromagnetic force

100

 the Gravitational force with which the Earth attracts the masses towards its center

what is weight

200

the resistance that one surface or object encounters when moving over another.


what is friction

200

states that, within some problem domain, the amount of momentum remains constant

what is law of conservation of momentum

200

 the force that holds protons and neutrons together.

what is strong nuclear force

200

a dimensionless quantity representing the amount of matter in a particle or object

what is mass

300

the friction between layers of a viscous fluid that are moving relative to each other.

what is fluid friction

300

is the motion of an object thrown (projected) into the air when, after the initial force that launches the object,

what is projectile motion

300

a fundamental force of nature that underlies some forms of radioactivity

what is weak nuclear force

300
the quantity of motion of a moving body, measured as a product of its mass and velocity.

what is momentum 

400

the SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second

what is newton

400

the frictional force that occurs when one object rolls on another

what is rolling friction

400

 the combined effect (the sum) of all the pushing and pulling forces actually acting on the object

what is net force

400

a force that attracts any two objects with mass

what is gravitational force

400

a tendency to do nothing or to remain unchanged.


what is inertia

500

a force that is caused by air.

what is air resistance

500

opposes the movement between two contact surfaces that slide against each other

what is sliding friction

500

The push or pull on an object with mass causes it to change its velocity.

what is force

500
a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.

what is centripetal force

500

the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
