No lab tables!
Tendency of an object to resist a change in motion.
Proportional to an object’s mass:
Large mass High Inertia Difficult to move
Small mass Low Inertia Easy to move
“Law of Inertia”
“Every object continues in a state of rest, or a state of motion in a straight line at constant speed, unless acted upon by an unbalanced force.”
Table Cloth Chaos
Force: Push or pull (measured in Newtons [N])
Contact Forces: Forces that exist between surfaces that are touching
Field Forces: Forces that exist between surfaces that are not touching
Example: A skydiver falling at constant velocity with an open parachute (ignore air resistance)
a = 0 m/s2
1. Object is drawn as a dot.
2. Force Vectors (): labeled and pointing in direction of force.
3. Arrows drawn starting from the dot, pointing away.
* 4. Draw acceleration and velocity vectors next to diagram.
Example: Free-body diagram of a
sky-diver with an open parachute
a = 0 m/s2
1. A ball hangs motionlessly from a cord.
2. A ball rests in the palm of a hand.
