Force, Motion, and Work
25
Frameofreference: Used to describe the motion of an object relative to a reference point
Velocity: Speed of an object in a particular direction
Speed: distance an object travels divided by the time
Displacement: distance from a starting point to an ending point
Acceleration: rate at which velocity changes
Force: a push or a pull
Friction: the force that opposes motion
Staticfriction: the type of friction that exists between stationary objects
Firstlaw: This law of motion states that an object at rest remains at rest while an object in motion remains in motion
Inertia: the tendency of an object to resist motion
Secondlaw: This law of motion states that force is equal to mass times acceleration
Weight: the force on an object due to gravity
Terminalvelocity: the constant velocity of a falling object when the force of air resistance is equal to the pull of gravity
ThirdLaw: This law of motion states that for every action, there is an equal and opposite reaction
Momentum: the product of the mass and the velocity of an object
Work: the product of force times distance; applying a force to move a object in a given direction
Joules: The unit for work and energy
Power: the rate at which work is done
Watts: the unit for power
Lever: this simple machine has 3 classes, depending on the position of the fulcrum
Pulley: this simple machine can either be fixed or movable
Screw: this simple machine is an inclined plane wrapped around a cylinder
Wedge: an axe is an example of this type of simple machine
Rubegoldberg: You completed this project by making a compound machine that completed a simple task
Mechanicaladvantage: a quantity that expresses how much a machine multiplies force or distance
