Force A push or pull
Newton The SI unit of force. It is to equal the force that would give a mass of one kilogram an acceleration of one meter per second.
Net Force Net Force is the overall force acting on an object.
Unbalanced forces It's when two forces acting on an object are in different size, causing a change in motion.
balanced forces Two forces acting in same directions in an object , and equal in size.
Friction The resistance that one surface or object encounters when moving over another.
Static friction Lacking into movement, action, or change.
Sliding friction Moving along a smooth surface while maintaining continuous contact with it.
Fluid friction A substance that has no fixed shape, liquid.
gravity the force that attracts the body toward the center of Earth.
mass typical large body of matter with no definite shape.
weight mass or quantity of matter contained by it giving it downward force.
free fall The motion of a falling when the only force is acting on its gravity.
air resistance The fluid friction experienced by objects falling through the air.
projectile An object that is thrown.
compression An elastic force that squeezes or pushes molecules in matter together.
tension An elastic force that stretches or pulls on the molecules in matter.
inertia The tendency of an object to resist any change in its object.
momentum The product of an object's mass and velocity.
law of conservation of momentum The rule that in the absence of outside forces the total momentum of objects that interact does not change.
satelite Any object that orbits around another object in space.
centripetal force A force that causes an object to move in a circle.
