Question Answer
Forcepush or pull that acts on an object
Forces can:cause an object that is not moving to start moving, stop an object that isn't moving, change the way an object is moving, change the shape of an object (squeezing, stretching, etc)
Types of forcesContact forces, action-at-a-distance forces
Contact forcesdirectly puts a force on an object
Types of contact forcesDirect pushes, tension force, friction force, elastic force
Action-at-a-distance forcesputs a force on an object without touching it (indirectly)
Types of action-at-a-distance forcesgravitational force, magnetic force, electrostatic force
Tension forceexperienced by a rope or wire when it is pulled at either end (contact force)
friction forceslow down or stop a moving object because of the surfaces rubbing together (contact force)
elastic forcea spring-like material restoring itself to its normal shape after it has been (contact force) compressed or stretched
gravitational forceacts between objects because they have mass (it can be on any 2 objects) (action-at-a-distance force)
Magnetic forcepushes or pulls on objects that have iron, nickel, or cobalt in them (action-at-a-distance force)
Electrostatic forcepushes or pulls between objects that have extra positive or negative charges on them (action-at-a-distance force)
Massamount of material in object (measured in g/kg and never changes)
weightamount of gravitational force on object (depends on the mass and where you are--how far away from earth you are)
Newtonin metric system, forces are measured in newtons(N)
Newtons are named after:Sir Isaac Newton
Force-metersuse a spring or other elastic device that is pushed or pulled
