The resistance that one surface/object encounters when moving over another
What is friction?
An influence that can cause an object to change its velocity
What is force?
A fundamental interaction which causes mutual attraction between all things that have mass
What is gravitational force?
A force acting opposite to the relative motion of any object moving with respect to a surrounding fluid
What is air resistance?
The unit of force in the International System of Units
What is the newton?
The force of friction on an object that is not moving
What is static friction?
The sum of all the forces acting on an object
What is net force?
A net force that acts on an object to keep it moving along a circular path
What is centripetal force?
The maximum velocity attainable by an object as it falls through a fluid
What is terminal velocity?
The tendency of objects in motion to stay in motion, and objects at rest to stay at rest, unless a force causes its speed or direction to change
What is inertia?
The opposition of movement between two contact surfaces that slide against each other
What is sliding friction?
A fundamental interaction that confines quarks into protons, neutrons, and other hadron particles
What is a strong nuclear force?
An attraction caused between particles with opposite charges and repulsion between particles with the same charge
What is electromagnetic force?
The motion of an object thrown or projected into the air, subject to only the acceleration of gravity
What is projectile motion?
The amount of matter or substance that makes up an object
What is mass?
The positive resisting motion when a rolling body is on a surface
What is rolling friction?
The force that allows protons to turn into neutrons and vice versa through beta decay
What is a weak nuclear force?
The product of the mass and velocity of an object
What is momentum?
The product of a body's mass and the acceleration due to gravity
What is weight?
The force that opposes a motion that takes place within fluids or in between fluids
What is fluid friction?
The statement that an in isolated system, the total momentum of two or more bodies acting upon each other remains constant unless an external force is applied
What is the law of conservation of momentum?
The universal force of attraction acting between all matter
What is gravity?
