If the external force on an object is not zero, the objet accelerates in the direction of the net fore. The magnitude of the acceleration is directly proportional to the net force and inversely proportional to the objects mass. . Elevator Rules. Elevators only travel up or down. Elevators speed up to a constant velocity. Elevators always slow down next after reaching a constant velocity. Elevators always slow down to a stop. Elevators always play bad music. The most important chapter of physics EVAR. What is a Force?. A force is a push or a pull. Contact forces:. Boat pulling a water skier. Pushing a car with a dead battery. Noncontact forces:. Gravitational attraction of moon to earth. PES 1000 – Physics in Everyday Life. Weight and Apparent Weight. Stationary weight: How do we sense weight while we stand motionless?. We sense the . pressure from the normal force . between our feet and the ground that is keeping us from falling through it.. Objects have a property called . inertia . which causes them to resist . changes. in their motion (Newton’s1. st. Law or Galileo’s law of inertia). .  . if it is at rest, it stays at rest.  if it is moving, it keeps moving with constant velocity. nd. Law algebraically and in words.. Draw an FBD: An object is at rest on an incline. State the Force statements that arise from the FBD.. A object is at rest on a flat surface. A 12.0 N force is applied East, and a force of friction acts with magnitude 8.0 N. Draw an FBD and determine the acceleration of the 4.00 kg mass..
