Question Answer
forceis a push or a pull that acts on an object.
net forceis the overall force acting on an object after all the forces are combined
newtonis the force that causes a 1-kilogram mass to accelerate at a rate of 1 meter per second each second (1 m/s2).
balanced forcethe net force is zero and there is no change in the objects motion
frictionforce that opposes the motion of an object that touch as they move past each other
static frictionthe friction force that acts on objects that are not moving
sliding frictiona force that opposes the direction of motion of an object as it slides over a surface
rolling frictiona friction force that acts on rolling objects
fluid frictionthe motion of an object through a fluid
air resistancefluid friction acting on an object moving through the air
gravitythe force that acts between any two masses
terminal velocitythe constant velocity of a falling object when the force of air resistance equals the force of gravity
projectile motionthe motion of a falling object after it is given an initial forward velocity
inertiathe tendency of an object to resist change in its motion
massthe measure of the inertia of an object depends on the amount of matter an object contains
accelerationnet force /mass
weightthe force of gravity acting on an object
"Weight Equals"mass x acceleration due to gravity
momentumthe product of an objects mass and its velocity
momentum formulamass x velocity
law of conservation of momentumno net force acts on a system than the total momentum of the system does not change
electromagnetic forceassocitated with charged particles
strong nuclear forcea powerful force of attraction that acts only on the neutons and protons in the nucleus, holding them together
weak nuclear forcean attraction force that only acts over a short range
gravitational forcean attraction force that acts between any two masses
centripetal forcea center directed force that continuously changes the direction of an object to make it move in a circe
