 # Force Magnitude Tension Elastic Force Gravity Normal Force

• Slides: 14 Force Magnitude Tension Elastic Force Gravity Normal Force Friction Drag 1 Force Magnitude Tension The magnitude of the tension is the same everywhere in the rope. 2 Force Magnitude Name of Force Tension Symbol 3 When does this force occur? If an object that is experiencing the force is pulling but not stretching another object Where does this force occur? On the object that is experiencing the force at the point where the pulling occurs Magnitude Determined using Newton’s Second Law Associated Energy No associated energy Force Magnitude Spring Force 4 Force Magnitude Name of Force Spring Force Symbol When does this force occur? If an object that is experiencing the force is stretching (or compressing) another object Where does this force occur? On the object experiencing the force where it connects to the object that stretches/compresses Magnitude Associated Energy 5 Elastic Potential Energy Force Magnitude Gravity 6 Force Magnitude Name of Force Gravity Symbol or When does this force occur? If there are two massive objects present Where does this force occur? At the center-of-mass of the object receiving the force Magnitude Associated Energy 7 or Gravitational Potential Energy Force Magnitude Gravity (near the earth’s surface) m Mass of the earth Radius of the earth 8 6 x 1024 kg 6. 375 x 106 m Force Magnitude Normal Force N m w 9 Force Magnitude 10 Name of Force Normal Force Symbol or When does this force occur? If an object touches the surface of another object Where does this force occur?
