strength or energy as an attribute of physical action or movement.
the resistance created by any two objects when sliding against each other
What is sliding friction
the maximum velocity (speed) attainable by an object as it falls through a fluid
what is terminal velocity
the quantity of motion of a moving body, measured as a product of its mass and velocity.
what is momentum
pulls objects with mass toward each other
what is gravitational force
force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second.
What is a newton
is the force resisting the motion when a body rolls on a surface.
What is rolling friction
the motion of an object thrown or projected into the air, subject to only the acceleration of gravity.
what is projectile motion
momentum is neither created nor destroyed, but only changed through the action of forces as described by Newton's laws of motion.
what is the law of conservation of momentum
What is centripetal force
the vector sum of forces acting on a particle or object.
What is net force
the friction between layers of a viscous fluid that are moving relative to each other.
what is fluid friction
a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
what is inertia
The direction of magnetic flux produced by a permanent magnet is always from N-pole to S-pole.
what is electromagnetic force
the resistance that one surface or object encounters when moving over another.
What is friction
the forces that are in opposition to the relative motion of an object as it passes through the air.
what is air resistance
a dimensionless quantity representing the amount of matter in a particle or object.
what is mass
a fundamental interaction that confines quarks into proton, neutron, and other hadron particles.
what is strong nuclear force
a force that keeps an object at rest
What is static friction
the universal force of attraction acting between all matter.
what is gravity
the Gravitational force with which the Earth attracts the masses towards its center.
what is weight
one of the four known fundamental interactions, with the others being electromagnetism, the strong interaction, and gravitation.
what is a weak nuclear force
